Abstract

The firearm has a firing mechanism containing a selection control (37) arranged to enable a firearm to function in a closed bolt firing mode, an open bolt firing mode, an automatic firing mode or a semi-automatic firing mode. A percussion mechanism activates a firing pin (10) enabling semiautomatic and automatic firing. A slide catch (36) enables a slide (7) to be held in a retracted position. The percussion mechanism obtains a synchronization enabling the firearm to function in a reversible manner in the closed bolt mode or open bolt mode according to the position of the selection control.

Description

L'invention concerne une arme à feu automatique.The invention relates to an automatic firearm.

Dans les armes automatiques de petit calibre, deux types de mécanismes sont adoptés en fonction de l'emploi visé, notamment :

  • les mécanismes de tir à culasse fermée caractérisés par la présence d'une cartouche dans la chambre de munitions avant le début du tir (démarré par pression de la détente), l'ensemble des pièces mobiles se trouvant en position prête au tir et la pression de la détente ne devant plus que libérer le mécanisme de mise à feu et percuter la munition; et,
  • les mécanismes de tir à culasse ouverte caractérisés par l'absence d'une cartouche dans la chambre avant le début du tir (également démarré par pression de la détente), les pièces mobiles étant retenues dans une position arrière et libérées lors de la pression par la pression sur la détente, le mécanisme devant alors alimenter une cartouche dans la chambre et verrouiller celle-ci avant de libérer le mécanisme de mise à feu et percuter la munition.
In small arms, two types of mechanisms are adopted depending on the intended use, including:
  • closed-breech shooting mechanisms characterized by the presence of a cartridge in the ammunition chamber prior to the start of firing (triggered by trigger pressure), all moving parts in ready-to-fire position and pressure the trigger must only release the firing mechanism and hit the ammunition; and,
  • open-head firing mechanisms characterized by the absence of a cartridge in the chamber before the start of firing (also triggered by trigger pressure), the moving parts being held in a rear position and released during the pressure by the pressure on the trigger, the mechanism must then feed a cartridge into the chamber and lock it before releasing the firing mechanism and hit the ammunition.

L'architecture de tir à culasse fermée est utilisée généralement dans les fusils car elle permet d'avoir une arme précise, une probabilité de tir du premier coup élevée, et une bonne résistance aux agressions de l'environnement (sable et poussières, boue).Closed-breech archery is generally used in rifles as it allows for a precise weapon, a high first shot probability, and good resistance to assault. the environment (sand and dust, mud).

Cette architecture présente l'inconvénient majeur de ne pouvoir tirer qu'un nombre de cartouches limité dans un temps donné (régime de tir) car passé ce nombre de cartouches, la chambre et le canon s'échauffent considérablement et, si le tir s'arrête avec une cartouche en chambre, celle-ci s'échauffe au point de s'enflammer spontanément.This architecture has the major disadvantage of being able to shoot a limited number of cartridges in a given time (firing regime) because past this number of cartridges, the chamber and the barrel heat up considerably and, if the shot stop with a cartridge in the room, it heats up to the point of igniting spontaneously.

Cet effet d'auto-inflammation de la poudre dans la cartouche est communément appelé cook-off.This self-ignition effect of the powder in the cartridge is commonly called cook-off.

Pour contrer cet inconvénient majeur, on utilise une architecture de tir à culasse ouverte. Celle-ci est caractérisée par le fait qu'avant le tir, l'ensemble des pièces mobiles est retenu en position arrière et qu'aucune munition ne se trouve présente dans la chambre.To counter this major drawback, we use an open bolt architecture. This is characterized by the fact that before firing, all the moving parts are retained in the rear position and no ammunition is present in the chamber.

Lors de la pression de la détente, cet ensemble est libéré : il alimente dans la chambre une cartouche qui est percutée lors de la fin de course avant du mécanisme.During the pressure of the trigger, this set is released: it feeds into the chamber a cartridge that is struck at the front end of the mechanism.

Ce principe de fonctionnement à culasse ouverte est régulièrement utilisé dans les mitrailleuses car il leur confère une grande capacité de tir sans risquer le problème d'auto-inflammation de la munition.This principle of open-head operation is regularly used in machine guns because it gives them a great shooting capacity without risking the self-ignition problem of the ammunition.

L'inconvénient de ce type d'architecture est la précision qui est moins bonne que dans un fusil à culasse fermée, ainsi qu'une résistance moins bonne à l'encrassement puisque lors des arrêts de tir, le mécanisme est en position arrière et la chambre est ouverte et est exposée à la contamination pas des débris, poussières ou autres pollutions de l'environnement.The disadvantage of this type of architecture is the accuracy which is less good than in a shotgun with a closed yoke, and a lower resistance to fouling since during firing stops, the mechanism is in the rear position and the chamber is open and is exposed to contamination not debris, dust or other environmental pollution.

Certaines armes ont été développées pour pallier à ces défauts. Il s'agit principalement des fusils automatiques FG-42 et la Johnson Machine Gun qui permettaient un tir semi-automatique à culasse fermée et un tir automatique à culasse ouverte. Ces armes n'apportent qu'une réponse incomplète au problème car il subsiste toujours le risque d'auto-inflammation en mode de tir semi-automatique et ces armes restent moins précises et exposées à la pollution de l'environnement dès qu'elles sont utilisées en mode de tir automatique.Some weapons have been developed to overcome these defects. These are mainly the FG-42 automatic rifles and the Johnson Machine Gun which allowed a semi-automatic shot with a closed breech and an automatic shot with an open breech. These weapons provide only an incomplete answer to the problem because there is always the risk of auto-ignition in semi-automatic firing mode and these weapons remain less precise and exposed to environmental pollution as soon as they are used in automatic firing mode.

Le brevet US 3.618.455 décrit une arme à feu qui permet aussi un tir semi-automatique à culasse fermée, mais qui ne permet pas un tir semi-automatique à culasse ouverte.The patent US 3,618,455 describes a firearm that also allows a semi-automatic shot with closed breech, but that does not allow a semi-automatic shot with open breech.

L'invention a pour but d'éviter les inconvénients susdits et porte sur une arme automatique selon la revendication 1 qui comporte en particulier un sélecteur de mode de tir pour changer du mode de tir automatique en mode de tir semi-automatique. L'arme est équipée d'un mécanisme de tir pourvu d'une commande de sélection permettant de faire fonctionner l'arme à feu en mode de tir à culasse fermée ou en mode de tir à culasse ouverte, ceci aussi bien en mode de tir automatique qu'en mode de tir semi-automatique.The invention aims to avoid the aforementioned drawbacks and relates to an automatic weapon according to claim 1 which comprises in particular a firing mode selector for changing the automatic firing mode in semi-automatic firing mode. The weapon is equipped with a firing mechanism provided with a selection command to operate the firearm in closed-breech shooting mode or in open-breech shooting mode, both in shooting mode automatic only in semi-automatic firing mode.

La sélection du mode de tir semi-automatique ou automatique s'effectue par un sélecteur de tir manipulable par l'utilisateur.The semi-automatic or automatic firing mode is selected by a user-selectable fire selector.

La sélection du mode de fonctionnement culasse fermée ou culasse ouverte s'effectue de préférence par un actuateur thermique connecté au canon.Selecting the operating mode cylinder head closed or Open cylinder is preferably made by a thermal actuator connected to the barrel.

Cet actuateur est activé par la chaleur dégagée par le canon et fait passer le mécanisme du mode culasse fermée au mode culasse ouverte avant que le canon n'atteigne la température critique à partir de laquelle il y a risque d'auto-inflammation de la cartouche si celle-ci reste un temps suffisamment long en chambre.This actuator is activated by the heat released by the barrel and moves the closed breech mode mechanism to open breech mode before the barrel reaches the critical temperature from which there is a risk of self-ignition of the cartridge if it stays long enough in the room.

Ceci permet d'avoir une arme précise et plus fiable lorsque la température du canon est basse et permet également de tirer des régimes de tirs élevés sans risquer le problème d'auto-inflammation de la cartouche.This makes it possible to have a precise and more reliable weapon when the barrel temperature is low and also makes it possible to shoot high firing regimes without risking the problem of auto-ignition of the cartridge.

Le brevet US 3.618.455 précité comprend un tel actuateur sensible à la température du canon. Cet actuateur comprend un cylindre rempli de mercure et un piston actionné par la dilatation du mercure sous l'effet de la chaleur dégagé par le canon lors d'un tir continué. L'inconvénient de cet actuateur est qu'il est trop peu sensible au voisinage de la température critique de cook-off.The patent US 3,618,455 aforementioned includes such an actuator sensitive to the temperature of the barrel. This actuator comprises a cylinder filled with mercury and a piston actuated by the expansion of the mercury under the effect of heat released by the barrel during a continuous firing. The disadvantage of this actuator is that it is too insensitive to the vicinity of the critical cook-off temperature.

Avantageusement l'arme automatique comporte :

  • un actuateur thermique connecté au canon;
  • un mécanisme de transfert du mouvement de l'actuateur thermique vers une tringle de commande;
  • une tringle de commande;
  • un mécanisme de tir comprenant un chien, une gâchette, appelée gâchette de glissière, et les éléments permettant de synchroniser ces 2 pièces.
Advantageously, the automatic weapon comprises:
  • a thermal actuator connected to the barrel;
  • a mechanism for transferring the movement of the thermal actuator to a control rod;
  • a control rod;
  • a firing mechanism comprising a dog, a trigger, called a slide trigger, and the elements to synchronize these two pieces.

L'invention concerne aussi un mécanisme de tir selon la revendication 20.The invention also relates to a firing mechanism according to claim 20.

L'arme à feu 1 selon l'invention comprend une carcasse 2; un chargeur à munitions 3; un canon 4 avec ; une détente 5 et un sélecteur 6 de tir à trois positions manipulable par l'utilisateur pour choisir entre un mode de tir automatique (repère A) ou semi-automatique, c'est-à-dire coup par coup (repère 1), ou un mode de sécurité (repère S).The firearm 1 according to the invention comprises a carcass 2; an ammunition magazine 3; a cannon 4 with; a trigger 5 and a user-selectable three-position firing selector 6 for choosing between an automatic firing mode (A mark) or semi-automatic firing, that is to say single shot (mark 1), or a security mode (S mark).

L'arme à feu 1 comprend aussi une glissière 7 pouvant coulisser dans la carcasse 2 dans le prolongement du canon 4 entre une position reculée et une position avancée afin de pouvoir charger une cartouche du chargeur 3 dans la chambre à munitions située dans l'annexe 4' du canon 4.The firearm 1 also comprises a slide 7 slidable in the carcass 2 in the extension of the barrel 4 between a retracted position and an advanced position in order to be able to load a cartridge of the charger 3 in the ammunition chamber located in the appendix 4 'of the barrel 4.

La glissière 7 est pourvue d'un ressort récupérateur 8 qui pousse la glissière 7 dans la direction du canon 4.The slide 7 is provided with a recovery spring 8 which pushes the slide 7 in the direction of the barrel 4.

La glissière 7 est pourvue d'un verrou 9 afin de pouvoir verrouiller une cartouche dans la chambre à munitions dans la position avancée de la glissière 7 et d'un percuteur 10 traversant la glissière dont une extrémité dépasse de l'arrière de la glissière 7. Un mécanisme de percussion est prévu pour actionner le percuteur 10.The slide 7 is provided with a latch 9 in order to be able to lock a cartridge in the ammunition chamber in the advanced position of the slide 7 and a striker 10 passing through the slide, one end protruding from the rear of the slide 7 A percussion mechanism is provided for actuating the striker 10.

Le sélecteur de tir 6 et la détente 5 font partie d'un mécanisme de tir 11 qui est représenté en éclaté dans la figure 4 et qui est relié au moyen d'un système de transfert 12 à un actuateur thermique 13 qui, comme représenté dans les figures 5 et 6, est connecté mécaniquement par une bague de connexion 14 au canon 4 et permet le passage du fonctionnement du mode « culasse fermée » vers le mode « culasse ouverte » quand la température du canon 4 atteint ou dépasse une température prédéterminée et inversement commande la transition du tir à culasse ouverte au tir à culasse fermée quand la température du canon redevient inférieure à une température prédéterminée.The firing selector 6 and the trigger 5 are part of a firing mechanism 11 which is shown exploded in the figure 4 and which is connected by means of a transfer system 12 to a thermal actuator 13 which, as shown in FIGS. figures 5 and 6 , is mechanically connected by a connecting ring 14 to the barrel 4 and allows the passage of the operation of the "closed cylinder head" mode to the "open cylinder head" mode when the temperature of the barrel 4 reaches or exceeds a predetermined temperature and conversely controls the transition of the open breech shooting when the barrel temperature falls below a predetermined temperature.

L'actuateur thermique 13 est un actuateur à changement de phase qui, comme représenté dans la figure 7, comprend un cylindre 15 et un piston 16 qui définit une chambre 17 à l'intérieur du cylindre 15, la chambre 17 étant remplie avec une substance qui change de phase à la température prédéterminée susdite, ce changement de phase s'accompagnant d'une variation volumique importante de l'ordre de 10% à 20% et qui, par exemple, passe de l'état solide à l'état liquide et par expansion due au changement de phase génère un mouvement du piston 16 dans le sens de la flèche A dans la figure 7.The thermal actuator 13 is a phase change actuator which, as shown in FIG. figure 7 , comprises a cylinder 15 and a piston 16 which defines a chamber 17 inside the cylinder 15, the chamber 17 being filled with a substance which changes phase at the aforementioned predetermined temperature, this phase change being accompanied by a large volume variation of the order of 10% to 20% and which, for example, passes from the solid state to the liquid state and by expansion due to the phase change generates a movement of the piston 16 in the direction of the arrow A in the figure 7 .

Cette position du piston 16 est transférée au mécanisme de tir 11 via le système de transfert 12 qui comprend un poussoir 18, un levier 19 pouvant basculer autour d'un axe 20 et un poussoir 21 connecté au mécanisme de tir 11 par une tringle de commande 22.This position of the piston 16 is transferred to the firing mechanism 11 via the transfer system 12 which comprises a pusher 18, a lever 19 that can swing about an axis 20 and a pusher 21 connected to the firing mechanism 11 by a control rod 22.

Un ressort de rappel 23 force le piston 16 à rentrer dans le cylindre 15 de l'actuateur thermique 13 lorsque la substance contenue dans la chambre 17 de l'actuateur thermique passe de l'état liquide à l'état solide, ce passage de l'état liquide à l'état solide s'accompagnant d'une contraction volumique importante.A return spring 23 forces the piston 16 to enter the cylinder 15 of the thermal actuator 13 when the substance contained in the chamber 17 of the thermal actuator changes from the liquid state to the solid state, this passage of the liquid state in the solid state accompanied by a large volume contraction.

Le mécanisme de tir 11 comprend un chien 24 qui fait partie du mécanisme de percussion et qui peut pivoter autour d'un axe 25 de la carcasse 2 pour frapper le percuteur 10 sous l'effet d'un ressort 26 qui est armé par le mouvement de recul de la glissière 7 et qui est libéré quand la détente 5 est pressée, pivote autour d'un pivot 27 et entraîne la gâchette de chien 28.The firing mechanism 11 comprises a dog 24 which is part of the percussion mechanism and which can pivot about an axis 25 of the carcass 2 to strike the striker 10 under the effect of a spring 26 which is armed by the movement retreating slide 7 and released when the trigger 5 is pressed, pivots about a pivot 27 and drives the dog trigger 28.

Le mécanisme de tir 11 est représenté plus en détail dans les figures 8 et 9 qui montrent la situation au repos avec le sélecteur de tir 6 dans la position de mode semi-automatique.The firing mechanism 11 is shown in more detail in the figures 8 and 9 which show the situation at rest with the fire selector 6 in the semi-automatic mode position.

Ces figures montrent que la détente 5 comprend une gâchette de chien 28 supporté par le pivot 27 pour maintenir le chien 24 en position armée tant que la détente 5 n'est pas actionnée et pour libérer le chien 24 quand la détente est pressée.These figures show that the trigger 5 comprises a dog trigger 28 supported by the pivot 27 to hold the dog 24 in the armed position until the trigger 5 is actuated and to release the dog 24 when the trigger is pressed.

A cette fin le chien 24 est pourvu d'un épaulement 29 qui peut coopérer avec la face avant 30 de la gâchette de chien 28 qui est pourvue d'un ressort de rappel 31 qui maintient cette face avant 30 en face de l'épaulement 29.For this purpose the dog 24 is provided with a shoulder 29 which can cooperate with the front face 30 of the dog trigger 28 which is provided with a return spring 31 which maintains this front face 30 opposite the shoulder 29.

La détente 5 est également munie d'une gâchette de coup par coup 32 permettant de bloquer le chien 31 en position armée tant que la détente 5 n'est pas relâchée après un tir.The trigger 5 is also provided with a blow-by-blow trigger 32 for locking the dog 31 in the armed position as the trigger 5 is not released after a shot.

Cette gâchette 32 de coup par coup est supportée par le pivot 27 de la détente et est maintenue en position haute par un ressort de rappel 33. La gâchette 32 est pourvue d'une queue d'accrochage 34 pouvant coopérer avec une queue d'accrochage 35 correspondante du chien 24.This trigger 32 by stroke is supported by the pivot 27 of the trigger and is held in the raised position by a return spring 33. The trigger 32 is provided with a hooking tail 34 which can cooperate with a hanging tail Corresponding to the dog 24.

Le sélecteur de mode de tir 6 permet de choisir le mode automatique ou semi-automatique et est prévu pour activer la gâchette de coup par coup 32 en mode de tir semi-automatique et de désactiver cette gâchette 32 en mode de tir automatique. Pour ce faire, l'axe du sélecteur 6 est profilé de telle manière que dans le mode automatique le mouvement de rotation de la gâchette 32 est bloqué par le sélecteur de tir 6, ce qui empêche l'accrochage de la queue d'accrochage 35 du chien 32 par la queue d'accrochage 34 de la gâchette 32, tandis que dans le mode semi-automatique, la gâchette de coup par coup 32 n'est pas bloquée en rotation et peut pivoter lorsque la détente est pressée pour permettre d'accrocher le chien 24 dans une position armée par l'intermédiaire de la queue d'accrochage 35 du chien 24 et de la queue d'accrochage 34 de la gâchette 32.The fire mode selector 6 makes it possible to choose the automatic or semi-automatic mode and is designed to activate the shot-by-shot trigger 32 in the semi-automatic firing mode and to deactivate this trigger 32 in the automatic firing mode. To do this, the axis of the selector 6 is profiled such that in the automatic mode the rotational movement of the trigger 32 is blocked by the firing selector 6, which prevents the hooking of the attachment tail 35 the dog 32 by the shank 34 of the trigger 32, while in the semi-automatic mode, the trigger shot 32 is not locked in rotation and can pivot when the trigger is pressed to allow to hook the dog 24 in an armed position via the hooking tail 35 of the dog 24 and the catching tail 34 of the trigger 32.

Le mécanisme de tir 11 comprend également une gâchette de glissière 36 et une commande de sélection 37 qui est commandée par l'actuateur thermique 13 via la tige de commande 22 et qui, selon la position de cette commande 37, permet de bloquer la gâchette de glissière 36 dans une position dégagée de la glissière 7 pour un tir à culasse fermée ou permet de libérer la gâchette de glissière 36 pour un tir à culasse ouverte afin de permettre à cette gâchette de glissière 36 d'arrêter et de bloquer le mouvement de la glissière 7 dans une position reculée comme montré dans la figure 8.The firing mechanism 11 also comprises a slide gate 36 and a selection command 37 which is controlled by the thermal actuator 13 via the rod of FIG. control 22 and which, depending on the position of this control 37, makes it possible to lock the slide gate 36 in an unobstructed position of the slideway 7 for a shot with a closed bolt or makes it possible to release the slide trigger 36 for an open breech shotgun to allow this slide trigger 36 to stop and block the movement of the slide 7 in a retracted position as shown in FIG. figure 8 .

La gâchette de glissière 36 se présente sous forme d'une pièce en forme de L et est montée avec une extrémité libre d'une manière pivotante autour d'un axe 38 fixé dans la carcasse 2.The slider trigger 36 is in the form of an L-shaped piece and is mounted with a free end in a pivoting manner about an axis 38 fixed in the carcass 2.

Un ressort de rappel 39 agissant sur le levier de commande 44 maintient la gâchette de glissière 36 en position haute de façon à ce que la gâchette de glissière puisse s'engager avec sa face supérieure dans une encoche 40 réalisée sur la partie arrière de la glissière 7.A return spring 39 acting on the control lever 44 holds the slide trigger 36 in the up position so that the slide trigger can engage with its upper face in a notch 40 made on the rear part of the slide. 7.

La commande de sélection 37 est réalisée sous forme d'un levier pivotant autour d'un axe 41 fixé dans la carcasse 2.The selection control 37 is made in the form of a lever pivoting about an axis 41 fixed in the carcass 2.

Dans la position correspondante au mode de tir à culasse fermée ce levier 37 peut bloquer la gâchette de glissière 36 dans une position dégagée de la glissière 7 en s'appuyant sur une protubérance 42 de la gâchette 36 comme indiqué dans la figure 18, tandis que dans la position correspondante au mode de tir à culasse ouverte comme indiqué dans la figure 8, le levier 37 ne peut pas empêcher le mouvement de la gâchette de glissière 36.In the position corresponding to the closed bolt firing mode, this lever 37 can lock the slide trigger 36 in an open position of the slide 7 by relying on a protrusion 42 of the trigger 36 as indicated in FIG. figure 18 , while in the corresponding position to the open-breech shooting mode as indicated in figure 8 the lever 37 can not prevent the movement of the slide trigger 36.

Un mécanisme de synchronisation 43 est prévu entre le chien 24 et la gâchette de glissière 36 et dans l'exemple représenté, entre la gâchette de coup par coup 32 et la gâchette de glissière 36.A synchronization mechanism 43 is provided between the dog 24 and the slide gate 36 and in the example shown, between the jogger trigger 32 and the slide gate 36.

Ce mécanisme de synchronisation (43) comprend un levier de commande 44 pouvant pivoter autour de l'axe 41 et est muni du ressort de gâchette 39.This synchronization mechanism (43) comprises a control lever 44 pivotable about the axis 41 and is provided with the trigger spring 39.

Une extrémité du levier de commande 44 est reliée avec une extrémité de la gâchette de glissière 36 par une articulation 45.One end of the control lever 44 is connected with one end of the slide gate 36 by a hinge 45.

L'autre extrémité du levier de commande 44 est pourvue d'un axe de rotation 46 supportant deux cliquets, c'est-à-dire un cliquet de mode semi-automatique 47 et un cliquet de mode automatique 48.The other end of the control lever 44 is provided with an axis of rotation 46 supporting two pawls, that is to say a semi-automatic mode ratchet 47 and an automatic mode ratchet 48.

Un ressort de cliquet 49 fait pivoter le cliquet semi-automatique 47 en direction de la détente et maintien le cliquet automatique 48 avec l'extrémité supérieure en contact avec le sélecteur dé tir 6 qui est profilé de telle manière que, dans la position semi-automatique, l'extrémité inférieure du cliquet 48 est dégagée de la détente 5 comme représenté dans la figure 10, tandis que dans la position automatique, cette extrémité inférieure repose sur une extrémité arrière de la détente 5 comme indiqué dans la figure 16.A pawl spring 49 rotates the semiautomatic pawl 47 in the direction of the detent and maintains the automatic pawl 48 with the upper end in contact with the firing selector 6 which is shaped such that in the half position automatically, the lower end of the pawl 48 is disengaged from the trigger 5 as shown in FIG. figure 10 , while in the automatic position, this lower end rests on a rear end of the trigger 5 as indicated in the figure 16 .

Le cliquet de mode semi-automatique 47 est pourvu d'une saillie 50 qui, quand le cliquet 47 s'appuie sur la détente 5, est située dans le trajet de rotation de la gâchette de coup par coup 32 quand celle-ci est actionnée vers le bas par le mouvement du chien 24 sous l'impulsion d'un cliquet de glissière 51 qui, lors du mouvement de recul de la glissière 7, fait descendre le chien 24 suffisamment loin pour dégager le cliquet semi-automatique 47 de la détente 5 par l'intermédiaire de la gâchette de coup par coup 32.The semi-automatic mode ratchet 47 is provided with a projection 50 which, when the pawl 47 is based on the trigger 5, is located in the path of rotation of the trigger shot by stroke 32 when it is actuated downwards by the movement of the dog 24 under the impulse a slide ratchet 51 which, during the retreating movement of the slide 7, causes the dog 24 to descend sufficiently far to disengage the semi-automatic ratchet 47 of the trigger 5 by means of the blow-by-blow trigger 32 .

Le mécanisme de synchronisation 43 comprend un levier de blocage 52 de la gâchette de chien 28 qui est monté d'une manière rotative sur l'axe 38 et qui est pourvue d'un crochet 53.The synchronization mechanism 43 includes a dog trigger locking lever 52 which is rotatably mounted on the shaft 38 and is provided with a hook 53.

Un ressort de rappel 54 exerce une force sur le levier de blocage 52 en direction de la gâchette de chien 28 et maintient le levier de blocage 52 en contact avec le sélecteur de tir 6 par l'intermédiaire d'un doigt 55.A return spring 54 exerts a force on the locking lever 52 in the direction of the dog trigger 28 and maintains the locking lever 52 in contact with the firing selector 6 via a finger 55.

Le levier de blocage 52 se trouve sous le contrôle du sélecteur de tir 6 qui, dans la position de mode de tir semi-automatique, bloque le levier de blocage 52 en position dégagée de la gâchette de chien 28, et, dans la position de mode de tir automatique, libère la position bloquée du levier de blocage 52 afin de permettre d'accrocher l'extrémité arrière de la gâchette de chien 28 sous l'effet du ressort 54 quand la détente 5 est pressée.The locking lever 52 is under the control of the firing selector 6 which, in the semi-automatic firing mode position, locks the locking lever 52 in the open position of the dog trigger 28, and in the position of automatic firing mode, releases the locked position of the lock lever 52 to allow to hang the rear end of the dog trigger 28 under the effect of the spring 54 when the trigger 5 is pressed.

La commande de sélection 37 mode culasse ouverte/culasse fermée est pourvue d'une dent radiale 56 pouvant s'engager derrière une dent 57 du levier de blocage 52 afin de dégager le levier de blocage 52 de la gâchette de chien 28.The open breech / closed breech selection control 37 is provided with a radial tooth 56 engageable behind a tooth 57 of the locking lever 52 in order to release the locking lever 52 of the dog trigger 28.

Une gâchette de fermeture basculante 58 permet de bloquer le chien 24 dans une position armée par action sur une butée 59 du chien 24 sous l'effet d'un ressort 60.A tilting closure trigger 58 makes it possible to block the dog 24 in an armed position by action on a stop 59 of the dog 24 under the effect of a spring 60.

Cette gâchette de fermeture 58 est maintenue en position de blocage du chien 24 tant que la glissière n'est pas arrivée proche de la fin de course du mouvement de fermeture de la glissière 7 et est libérée par le contact avec une butée de fin de course 61 à la partie arrière de la glissière 7.This closing trigger 58 is held in the blocking position of the dog 24 until the slide has reached the end of the closing movement of the slide 7 and is released by contact with a limit stop. 61 at the rear part of the slide 7.

Le fonctionnement et l'utilisation de l'arme varient selon la sélection du mode de tir automatique ou semi-automatique et selon la position de la commande de sélection mode de tir culasse ouverte ou culasse fermée, commandé par l'actuateur thermique 13 en fonction de la température du canon 4.The operation and use of the weapon vary according to the selection of the automatic or semi-automatic firing mode and according to the position of the selection control firing mode open cylinder head or cylinder head closed, controlled by the thermal actuator 13 in function the temperature of the barrel 4.

On peut distinguer quatre modes d'opération :

  • tir à culasse ouverte / mode de tir semi-automatique ;
  • tir à culasse ouverte / mode de tir automatique ;
  • tir à culasse fermée / mode de tir semi-automatique ;
  • tir à culasse fermée / mode de tir automatique.
There are four modes of operation:
  • open breech shot / semi-automatic firing mode;
  • open breech shot / automatic shooting mode;
  • closed breech shot / semi-automatic firing mode;
  • closed breech shot / automatic shooting mode.

Dans ce qui suit le fonctionnement sera expliqué pour chacun de ces modes d'opération.In what follows the operation will be explained for each of these modes of operation.

"Tir à culasse ouverte", mode de tir semi-automatique"Open breech shot", semi-automatic shooting mode

La situation au repos est représentée dans les figures 8, 9 et 10.The situation at rest is represented in figures 8 , 9 and 10 .

Ce mode de tir est caractérisé par une position du sélecteur de tir 6 sur la position coup par coup et une position de la tringle de commande 22 vers l'avant de l'arme.This mode of fire is characterized by a position of the firing selector 6 on the position shot by blow and a position of the control rod 22 towards the front of the weapon.

La position de la tringle de commande 22 est définie par le mouvement de sortie du piston 16 lorsque l'actuateur thermique 13 se trouve à une température supérieure à la température de changement de phase.The position of the control rod 22 is defined by the output movement of the piston 16 when the thermal actuator 13 is at a temperature above the phase change temperature.

Le mouvement vers l'avant de la tringle de commande 22, illustré par la flèche B, fait pivoter le levier 37 qui libère le levier de blocage 52. Le levier de blocage 52 a une position définie par le ressort 54 et l'action du sélecteur de tir 6 sur l'extrémité 55 ce qui lui interdit de bloquer la gâchette de chien 28.The forward movement of the control rod 22, illustrated by the arrow B, pivots the lever 37 which releases the locking lever 52. The locking lever 52 has a position defined by the spring 54 and the action of the fire selector 6 on the end 55 which prevents him from blocking the dog trigger 28.

Le mouvement vers l'avant de la tringle de commande 22, illustré par la flèche B, fait pivoter le levier 37 qui libère également la gâchette de glissière 36 de sa position abaissée.The forward movement of the control rod 22, illustrated by the arrow B, pivots the lever 37 which also releases the slide trigger 36 from its lowered position.

Le cliquet de mode semi-automatique 47 est en appui sur la détente 5 sous l'effet du ressort 49 et le cliquet de mode automatique 48 est dégagé de la détente 5 sous l'effet du ressort 49 et du dégagement présent dans le sélecteur de tir 6.The semi-automatic mode ratchet 47 is supported on the trigger 5 under the effect of the spring 49 and the automatic mode ratchet 48 is disengaged from the trigger 5 under the effect of the spring 49 and the clearance present in the selector. shot 6.

La glissière 7 est maintenue en position arrière par la gâchette de glissière 36 et le chien 24 se trouve maintenu en position armée par la glissière 7.The slide 7 is held in the rear position by the trigger slide 36 and the dog 24 is held in the armed position by the slide 7.

Lors de la pression sur la détente 5, illustrée dans la figure 11 par la flèche C, la face avant 30 de la détente se dégage de l'épaulement 29 du chien 24, le chien 24 étant en appui sur la glissière 7.When pressing the trigger 5, illustrated in the figure 11 by the arrow C, the front face 30 of the trigger disengages from the shoulder 29 of the dog 24, the dog 24 resting on the slide 7.

En même temps, le cliquet de mode semi-automatique 47 est soulevé par l'arrière de la détente 5. Ce cliquet 47 fait basculer le levier de commande 44 autour de l'axe 41 et ce basculement abaisse la gâchette de glissière 36 comme indiquée par flèche D, ce qui a pour effet de libérer la glissière 7 qui entame un mouvement vers l'avant (flèche E) sous l'action du ressort récupérateur 8.At the same time, the semi-automatic mode ratchet 47 is lifted by the rear of the trigger 5. This pawl 47 tilts the control lever 44 about the axis 41 and this tilting lowers the slide trigger 36 as indicated by arrow D, which has the effect of releasing the slide 7 which starts a movement forward (arrow E) under the action of the recovery spring 8.

Lors du mouvement E de la glissière 7 vers l'avant, le verrou 9, logé dans la glissière 7, sort alors une cartouche du chargeur et la place dans la chambre dans l'annexe 4' du canon 4. Pendant ce même mouvement E le chien 24 vient en contact avec la gâchette de fermeture 58.During the movement E of the slide 7 towards the front, the latch 9, housed in the slide 7, then leaves a cartridge of the magazine and places it in the chamber in the annex 4 'of the barrel 4. During this same movement E the dog 24 comes into contact with the closing trigger 58.

En poursuivant son mouvement E vers l'avant, la glissière 7 fait tourner le verrou 9 dans l'annexe 4' de canon 4, puis dans la dernière phase du mouvement E fait pivoter la gâchette de fermeture 58 par son contact avec la butée 61 à l'arrière de la glissière 7 comme représenté dans la figure 12, ce qui libère le chien 24 et permet la percussion de la cartouche présente dans la chambre par le basculement du chien 24 dans le sens de la flèche F sous l'effet du ressort 26.Continuing its forward movement E, the slide 7 rotates the latch 9 in the barrel 4 annex 4 ', then in the last phase of the movement E rotates the closing trigger 58 by its contact with the stop 61 at the back of the slide 7 as shown in the figure 12 , which releases the dog 24 and allows the percussion of the cartridge present in the chamber by the tilting of the dog 24 in the direction of the arrow F under the effect of the spring 26.

Sous l'effet de l'emprunt de gaz au niveau de la frette, la glissière 7 reçoit une impulsion qui génère le mouvement de recul de cette glissière 7, ce qui fait pivoter le chien 24 autour de l'axe 25 dans le sens opposé de la flèche F.Under the effect of the borrowing of gas at the hoop, the slide 7 receives a pulse which generates the recoil movement of this slide 7, which causes the dog 24 to pivot about the axis 25 in the opposite direction arrow F.

Selon l'illustration de la figure 13, lorsque le cliquet de glissière 51 entre en contact avec le chien 24, ce cliquet 51 fait descendre le chien 24 en position basse, le chien 24 heurte la gâchette de coup par coup 32 qui fait à son tour pivoter le cliquet de mode semi-automatique 47 par son contact avec la saillie 50.According to the illustration of the figure 13 when the slide catch 51 contacts the dog 24, the catch 51 moves the dog 24 down, the dog 24 hits the shot trigger 32 which in turn rotates the half-way pawl automatic 47 by its contact with the projection 50.

En pivotant, ce cliquet 47 se dégage de la détente 5, ce qui a pour effet de libérer le levier de commande 44 qui pivote autour de son axe sous l'effet du ressort de gâchette 39 et permet à la gâchette de glissière 36 de remonter dans le sens de la flèche D'.By pivoting, this pawl 47 disengages from the trigger 5, which has the effect of releasing the control lever 44 which pivots about its axis under the effect of the trigger spring 39 and allows the slide trigger 36 to go up in the direction of the arrow D '.

Lorsque la glissière 7 aura été en fin de course dans la carcasse 2 et reviendra à hauteur de la gâchette de glissière 36, elle sera arrêtée par la gâchette 36.When the slide 7 has been end of stroke in the carcass 2 and will return to the height of the slide trigger 36, it will be stopped by the trigger 36.

Le chien 24 reste alors maintenu en position basse par la gâchette de coup par coup 32 dont la queue d'accrochage 34 s'accroche derrière la queue d'accrochage 35 du chien 24, comme illustré par la figure 14, jusqu'à ce que le tireur relâche la pression sur la détente 5. Lorsque le tireur relâche la détente 5, la gâchette de coup par coup 32 est désengagée du chien 24 et le chien 24 est retenu en position armée par son contact avec la glissière 7.The dog 24 then remains kept in the down position by the blow-by-blow trigger 32 whose hooking tail 34 hooks behind the hooking tail 35 of the dog 24, as illustrated by FIG. figure 14 , until the shooter releases the pressure on the trigger 5. When the shooter releases the trigger 5, the trigger shot by blow 32 is disengaged from the dog 24 and the dog 24 is held in the armed position by its contact with the slide 7.

Lorsque le tireur aura relâché la détente 5, le cliquet 47 se remettra en position sur la détente 5 sous l'effet du ressort 49.When the shooter has released the trigger 5, the pawl 47 will be in position on the trigger 5 under the effect of the spring 49.

"Tir à culasse ouverte", mode de tir automatique"Open breech shot", automatic shooting mode

Ce mode de tir est caractérisé par une position du sélecteur de tir 6 sur la position automatique et une position de la tringle de commande 22 vers l'avant de l'arme.This mode of fire is characterized by a position of the firing selector 6 on the automatic position and a position of the control rod 22 towards the front of the weapon.

La situation au repos est illustrée dans les figures 15 et 16.The situation at rest is illustrated in the figures 15 and 16 .

La position de la tringle de commande 22 est définie par le mouvement de sortie A du piston 16 lorsque l'actuateur thermique 13 se trouve à une température supérieure à la température de changement de phase.The position of the control rod 22 is defined by the output movement A of the piston 16 when the thermal actuator 13 is at a temperature above the phase change temperature.

La tringle de commande 22 entraîne le levier de blocage 37 dans le mouvement B, ce qui permet le relèvement D' de la gâchette de glissière 36 et libère également le levier 52.The control rod 22 drives the locking lever 37 in the movement B, which allows the raising D 'of the slide gate 36 and also releases the lever 52.

Le levier de blocage 52 n'est plus maintenu dégagé de la gâchette de chien 28 par l'axe du sélecteur de tir 6 ce qui permettra au levier de blocage 52 de basculer autour de son axe 38 sous l'effet du ressort 54, ce qui fait que lorsque la détente 5 sera pressée, le levier de blocage 52 viendra bloquer la gâchette de chien 28 par l'action du crochet 53. Au repos, comme illustré en figure 16, le cliquet de mode semi-automatique 47 est en appui sur la détente 5 sous l'effet du ressort 49 et le cliquet de mode automatique 48 est également en appui sur la détente 5 par son appui sur l'axe du sélecteur de tir 6.The locking lever 52 is no longer kept clear of the dog trigger 28 by the axis of the firing selector 6 which will allow the locking lever 52 to swing about its axis 38 under the effect of the spring 54, which makes that when the trigger 5 is pressed, the locking lever 52 will come to block the dog trigger 28 by the action of the hook 53. At rest, as illustrated in figure 16 , the semi-automatic mode ratchet 47 is resting on the trigger 5 under the effect of the spring 49 and the automatic mode ratchet 48 is also supported on the trigger 5 by its support on the axis of the firing selector 6 .

La glissière 7 est maintenue en position arrière par la gâchette de glissière 36, le chien 24 se trouve maintenu en position armée par son contact sur la glissière 7.The slide 7 is held in the rear position by the slide trigger 36, the dog 24 is held in the armed position by its contact on the slide 7.

Lors de la pression C sur la détente 5 illustrée dans la figure 17, le cliquet de mode automatique 48 est soulevé par l'arrière de la détente 5 et fait basculer le levier de commande 44 autour de l'axe 41 et ce basculement abaisse la gâchette de glissière 36 en direction D, ce qui a pour effet de libérer la glissière 7 qui entame un mouvement E vers l'avant sous l'action du ressort récupérateur 8.At the pressure C on the trigger 5 illustrated in the figure 17 , the automatic mode ratchet 48 is lifted by the rear of the trigger 5 and tilts the control lever 44 about the axis 41 and this tilting lowers the slide trigger 36 in direction D, which has the effect of release the slide 7 which initiates a forward movement E under the action of the recovery spring 8.

La pression C sur la détente 5 dégage la face 30 de la gâchette 28 de la face 29 du chien 24, le chien 24 étant en appui contre la glissière 7, puis venant avec son épaulement 59 contre la gâchette de fermeture 58 lorsque la glissière 7 aura avancé plus avant.The pressure C on the trigger 5 releases the face 30 of the trigger 28 of the face 29 of the dog 24, the dog 24 being in abutment against the slide 7, then coming with its shoulder 59 against the closing trigger 58 when the slide 7 will have advanced further.

Lors de la pression C sur la détente, le levier 52 vient bloquer la gâchette de chien 28 en position dégagée avec son crochet 53, ce qui permettra au chien 24 de s'abattre, même si la détente 5 est relâchée.During the pressure C on the trigger, the lever 52 comes to block the dog trigger 28 in the open position with its hook 53, which will allow the dog 24 to fall down, even if the trigger 5 is released.

Lorsque la détente 5 sera relâchée, le tir ne s'arrêtera que par l'action de la gâchette de glissière 36 qui bloquera la glissière 7 en position arrière.When the trigger 5 is released, the shooting will only stop by the action of the slide trigger 36 which will block the slide 7 in the rear position.

Afin d'empêcher le fonctionnement en mode semi-automatique, le mouvement de la gâchette de coup par coup 32 ne peut s'effectuer lors de la pression de la détente 5 en raison de la butée de cette gâchette 32 sur le sélecteur de tir 6.In order to prevent the operation in semi-automatic mode, the movement of the shot-by-shot trigger 32 can not take place during the pressure of the trigger 5 because of the stop of this trigger 32 on the firing selector 6 .

Le verrou 9 logé dans la glissière 7 sort alors une cartouche du chargeur 3 et la place dans la chambre. La glissière 7 fait tourner le verrou 9 dans l'annexe 4' de canon 4, puis dans la dernière phase du mouvement, fait pivoter la gâchette de fermeture 58, ce qui libère le chien et permet la percussion de la cartouche.The latch 9 housed in the slide 7 then pulls a cartridge from the magazine 3 and places it in the chamber. The slide 7 rotates the latch 9 in the barrel 4 annex 4 ', then in the last phase of the movement, rotates the closing trigger 58, which releases the dog and allows the percussion of the cartridge.

Sous l'effet de l'emprunt de gaz au niveau de la frette, la glissière 7 reçoit une impulsion qui génère un mouvement vers l'arrière de cette glissière 7, ce qui fait pivoter le chien 24 autour de l'axe 25. Lorsque le cliquet de glissière 51 entre en contact avec le chien 24, ce cliquet 51 fait pivoter le chien 24 en position basse.Under the effect of the gas borrowing at the hoop, the slide 7 receives a pulse which generates a movement towards the rear of this slide 7, which causes the dog 24 to pivot about the axis 25. When the ratchet 51 makes contact with the dog 24, this pawl 51 rotates the dog 24 in the low position.

Comme le cliquet de mode automatique 48 est maintenu en appui sur la détente 5 par son contact avec l'axe du sélecteur de tir 6, le levier de commande 44 ne peut pivoter autour de son axe 41 et maintient la gâchette de glissière 36 en position escamotée tant que la détente 5 reste pressée.As the automatic mode ratchet 48 is held in abutment on the trigger 5 by its contact with the axis of the firing selector 6, the control lever 44 can not pivot about its axis 41 and keeps the slide gate 36 in position retracted while the trigger 5 remains pressed.

Lorsque la glissière 7 aura été en fin de course dans la carcasse 2 et reviendra à hauteur de la gâchette de glissière 36, elle ne pourra pas être arrêtée par cette gâchette 36 et l'arme continuera de tirer jusqu'à ce que le tireur relâche sa pression sur la détente 5.When the slide 7 has been end of stroke in the carcass 2 and will return to the height of the slide trigger 36, it can not be stopped by this trigger 36 and the weapon will continue to fire until the shooter releases its pressure on the trigger 5.

"Tir à culasse fermée", mode de tir semi-automatique"Closed breech shot", semi-automatic shooting mode

Ce mode de tir est caractérisé par une position du sélecteur de tir 6 sur la position « 1 » coup par coup et une position B' de la tringle de commande 22 vers l'arrière de l'arme 1. La situation au repos est montrée dans les figures 18 et 19.This firing mode is characterized by a position of the firing selector 6 on the position "1" shot by shot and a position B 'of the control rod 22 toward the rear of the weapon 1. The situation at rest is shown in the figures 18 and 19 .

La position B' de la tringle de commande 22 est définie par la pression l'effort du ressort 23 qui fait rentrer le piston 16 lorsque l'actuateur thermique 13 se trouve à une température inférieure à la température de changement de phase.The position B 'of the control rod 22 is defined by the pressure force of the spring 23 which retracts the piston 16 when the thermal actuator 13 is at a temperature below the phase change temperature.

Ce ressort 23 fait reculer la tringle de commande 22 par l'intermédiaire du poussoir 21.This spring 23 moves the control rod 22 back by means of the pusher 21.

La tringle de commande 22 dans sa position arrière B' libère le levier de blocage 37 qui s'appuiera sur la protubérance 42 de cette gâchette 36 et bloquera la gâchette 36 par l'action du levier de blocage 37 sur la protubérance 42 lorsque cette gâchette 36 aura pivoté dans le sens D, ce qui interdira le relèvement ultérieur de la gâchette de glissière 36 et ce qui en même temps dégage les cliquets de mode semi-automatique 47 et de mode automatique 48 de la détente 5.The control rod 22 in its rear position B 'releases the locking lever 37 which will rely on the protrusion 42 of this trigger 36 and block the trigger 36 by the action of the locking lever 37 on the protrusion 42 when this trigger 36 will pivot in the direction D, which prohibit the subsequent raising of the slide trigger 36 and at the same time releases the ratchets semi-automatic mode 47 and automatic mode 48 of the trigger 5.

Le levier 52 est maintenu dégagé de la gâchette de chien 28 par l'action du levier 37 par l'engagement de la dent 56 derrière la dent 57 du levier 52 qui pour cette raison ne pourra pas bloquer la gâchette de chien 28.The lever 52 is kept clear of the dog trigger 28 by the action of the lever 37 by engagement of the tooth 56 behind the tooth 57 of the lever 52 which for this reason can not block the dog trigger 28.

Au repos, la glissière 7 se trouve en position avant sous l'effet du ressort récupérateur 8, le chien 24 se trouve maintenu en position armée par la gâchette de chien 28 par le contact de l'épaulement 29 du chien 24 avec la face avant 30 de la gâchette de chien 28. La gâchette de fermeture 58 est en même temps tenu dégagée de la butée de chien 59 par le contact avec la butée de fin de course de la glissière 7.At rest, the slide 7 is in the forward position under the effect of the recovery spring 8, the dog 24 is held in the armed position by the dog trigger 28 by the contact of the shoulder 29 of the dog 24 with the front face 30 of the dog trigger 28. The closing trigger 58 is at the same time kept clear of the dog stopper 59 by contact with the end stop of the slide 7.

Lors de la pression C sur la détente 5, illustrée à la figure 20, la gâchette de chien 28 se dégage et libère le chien 24, ce qui permet la percussion F de la cartouche par l'impact sur le percuteur 10.At the pressure C on the trigger 5, illustrated in FIG. figure 20 , the dog trigger 28 disengages and releases the dog 24, which allows the percussion F of the cartridge by the impact on the striker 10.

La gâchette de coup par coup 32 se place également en position haute sous l'effet du ressort 33.The trigger shot by blow 32 is also placed in the high position under the effect of the spring 33.

Sous l'effet de l'emprunt de gaz au niveau de la frette, la glissière 7 reçoit une impulsion qui génère le mouvement E' de la glissière 7 vers l'arrière comme illustré dans la figure 21, ce qui fait pivoter le chien 24 autour de l'axe 25 pour armer le ressort de chien 26.Under the effect of the gas borrowing at the hoop, the slide 7 receives a pulse which generates the movement E 'of the slide 7 towards the rear as shown in FIG. figure 21 , which causes the dog 24 to pivot about the axis 25 to arm the dog spring 26.

Lorsque le cliquet de glissière 51 entre en contact avec le chien 24, ce cliquet 51 fait pivoter le chien 24 en position basse et la queue d'accrochage 35 du chien 24 passe sous la queue d'accrochage 34 de la gâchette de coup par coup 32.When the slider ratchet 51 comes into contact with the dog 24, this pawl 51 rotates the dog 24 in the lower position and the hooking tail 35 of the dog 24 passes under the attachment tail 34 of the trigger shot by stroke 32.

Lorsque la glissière 7 aura été en fin de course dans la carcasse, elle effectuera l'alimentation de la cartouche suivante et s'arrêtera en position avant sous l'effet du ressort récupérateur 8, illustré dans la figure 22.When the slide 7 has been end of stroke in the carcass, it will supply the next cartridge and stop in the forward position under the effect of the recovery spring 8, illustrated in the figure 22 .

Le chien 24 reste alors maintenu en positon basse par la gâchette de coup par coup 32 jusqu'à ce que le tireur relâche sa pression sur la détente 5. Lorsque le tireur relâche la détente 5, la gâchette de coup par coup 32 est désengagée du chien 24 et le chien 24 est retenu en position armée par l'appui de la face 30 de la gâchette de chien 28 sur la face 29 du chien 24.The dog 24 then remains kept in low position by the trigger shot by blow 32 until the shooter releases its pressure on the trigger 5. When the shooter releases the trigger 5, the trigger shot by blow 32 is disengaged from the dog 24 and the dog 24 is held in the armed position by the support of the face 30 of the dog trigger 28 on the face 29 of the dog 24.

"'Tir à culasse fermée", mode de tir automatique"'Closed breech shot", automatic shooting mode

Ce mode de tir est caractérisé par une position du sélecteur de tir 6 sur la position automatique et une position B' de la tringle de commande 22 vers l'arrière de l'arme 1. La situation au repos est illustrée dans la figure 23.This firing mode is characterized by a position of the firing selector 6 on the automatic position and a position B 'of the control rod 22 towards the rear of the weapon 1. The situation at rest is illustrated in FIG. figure 23 .

La position B' de la tringle de commande 22 est définie par la pression l'effort du ressort 23 qui fait rentrer le piston 16 lorsque l'actuateur thermique 13 se trouve à une température inférieure à la température de changement de phase.The position B 'of the control rod 22 is defined by the pressure force of the spring 23 which retracts the piston 16 when the thermal actuator 13 is at a temperature below the phase change temperature.

Ce ressort 23 fait reculer la tringle de commande 22 par l'intermédiaire du poussoir 21. La tringle de commande 22, dans sa position arrière B', libère le levier de blocage 37 qui s'appuie contre la gâchette de glissière 36 sous l'effet du ressort 39 et maintient la gâchette de glissière 36 en position basse.This spring 23 moves the control rod 22 back by means of the pusher 21. The control rod 22, in its rear position B 'releases the locking lever 37 which rests against the slide gate 36 under the effect of the spring 39 and keeps the slide gate 36 in the low position.

Ce levier de blocage 37 interdira le relèvement de la gâchette de glissière 36, et, par l'intermédiaire du levier de commande 44, dégage les cliquets de mode semi-automatique 47 et de mode automatique 48 de la détente 5.This locking lever 37 will prohibit the raising of the slide gate 36, and, via the control lever 44, releases the pawls of semi-automatic mode 47 and automatic mode 48 of the trigger 5.

Le levier de blocage 52 est maintenu dégagé de la gâchette de chien 28 par l'action du levier 37 qui s'engage avec sa dent 56 derrière la dent 57 du levier 52 et de ce fait ne pourra pas bloquer la gâchette de chien 28.The locking lever 52 is kept free of the dog trigger 28 by the action of the lever 37 which engages with its tooth 56 behind the tooth 57 of the lever 52 and thus can not block the dog trigger 28.

La glissière 7 se trouve au repos en position avant sous l'effet du ressort récupérateur 8 et maintient la gâchette de fermeture 58 dégagée de la butée de chien 59.The slide 7 is at rest in the forward position under the effect of the recovery spring 8 and keeps the closing trigger 58 released from the dog stopper 59.

Le chien 24 se trouve maintenu en position armée par la gâchette de chien 28.The dog 24 is held in the armed position by the dog trigger 28.

Lors de la pression C sur la détente 5, illustrée dans la figure 24, la gâchette de chien 28 se dégage et libère le chien 24, ce qui permet la percussion de la cartouche.When the pressure C on the trigger 5, illustrated in the figure 24 , the dog trigger 28 disengages and releases the dog 24, which allows the percussion of the cartridge.

La gâchette de coup par coup 32 ne peut pas se placer en position haute en raison de son contact avec le sélecteur de tir 6, ce qui empêchera le tir en mode semi-automatique. Sous l'effet de l'emprunt de gaz au niveau de la frette, la glissière 7 reçoit une impulsion qui génère le mouvement de la glissière 7 vers l'arrière, ce qui fait pivoter le chien 24 autour de l'axe 25.The shot-by-shot trigger 32 can not be placed in the up position because of its contact with the firing selector 6, which will prevent firing in semi-automatic mode. Under the effect of the gas borrowing at the hoop, the slide 7 receives a pulse which generates the movement of the slide 7 towards the rear, which causes the dog 24 to pivot about the axis 25.

Lorsque le cliquet de glissière 51 entre en contact avec le chien 24, ce cliquet 51 fait pivoter le chien 24 en position basse, puis le chien 24 est retenu en position armée par son contact contre la glissière 7.When the slider ratchet 51 comes into contact with the dog 24, this pawl 51 rotates the dog 24 in the lower position, then the dog 24 is held in the armed position by its contact against the slider 7.

Lorsque la glissière 7 aura été en fin de course dans la carcasse elle effectuera l'alimentation de la cartouche suivante et s'arrêtera en position avant sous l'effet du ressort récupérateur 8. Avant d'atteindre sa position avant, la glissière 7 libère le chien 24 qui sera arrêté par la gâchette de fermeture 58, puis la glissière 7 actionne la gâchette de fermeture 58 par le contact avec la butée de fin de course 61, ce qui a pour effet de libérer le chien 24 et de permettre le départ du coup suivant.When the slide 7 has been at the end of the race in the carcass it will supply the next cartridge and stop in the forward position under the effect of the recovery spring 8. Before reaching its forward position, the slide 7 releases the dog 24 which will be stopped by the closing trigger 58, then the slide 7 actuates the closing trigger 58 by contact with the end stop 61, which has the effect of releasing the dog 24 and allowing the departure the next shot.

L'arme continuera donc à tirer jusqu'à ce que le tireur relâche sa pression sur la détente 5 et que par ce fait la gâchette de chien 28 peut revenir en position de repos et peut retenir le chien 24 en position armée.The weapon will therefore continue to fire until the shooter releases its pressure on the trigger 5 and that thereby the dog trigger 28 can return to the rest position and can hold the dog 24 in the armed position.

D'une manière plus générale on peut dire que les modes d'opération décrites ci-avant sont possible grâce aux profil de l'axe du sélecteur de tir et de l'action de la commande de sélection 37 pour passer de mode de tir à culasse ouverte au mode de tir à culasse fermée.More generally, it can be said that the modes of operation described above are possible thanks to the profile of the axis of the firing selector and the action of the selection control 37 to switch from firing mode to open breech with closed breech shot mode.

D'une part, le profil de l'axe du sélecteur de tir 6 est tel que :

  • dans la position de mode de tir semi-automatique ou coup par coup :
    • le cliquet de mode automatique 48 est dégagé de la détente 5;
    • le levier de blocage 52 de la gâchette de chien 28 est dégagé de la gâchette de chien 28;
    • la gâchette de coup par coup 32 n'est pas bloquée en rotation et peut retenir le chien 24 en position armée tant que la détente 5 est pressée; et que,
  • dans la position de mode de tir automatique:
    • le cliquet de mode automatique 48 est en appui sur la détente 5;
    • le levier de blocage 52 de la gâchette de chien 28 peut bloquer la gâchette de chien 28 lorsque la détente 5 est pressée;
    • la gâchette de coup par coup 32 est bloquée en rotation et ne peut pas retenir le chien 24 en position armée.
On the one hand, the profile of the axis of the firing selector 6 is such that:
  • in the semi-automatic or shot-by-shot firing mode position:
    • the automatic mode ratchet 48 is disengaged from the trigger 5;
    • the lock lever 52 of the dog trigger 28 is disengaged from the dog trigger 28;
    • the trigger shot 32 is not locked in rotation and can hold the dog 24 in the armed position as the trigger 5 is pressed; and,
  • in the automatic firing mode position:
    • the automatic mode ratchet 48 is in support on the trigger 5;
    • the lock lever 52 of the dog trigger 28 can lock the dog trigger 28 when the trigger 5 is pressed;
    • the trigger shot 32 is locked in rotation and can not hold the dog 24 in the armed position.

D'autre part, la commande de sélection 37 permet que :

  • dans la position de mode de tir à culasse fermée :
    • la gâchette de glissière 36 est bloquée dans une position dégagée de la glissière;
    • le levier de blocage 52 est dégagé de la gâchette de chien 28 afin de permettre un mouvement libre de la gâchette de chien 28;
  • dans la position de mode de tir à culasse ouverte :
    • la commande de sélection 37 n'empêche pas le mouvement de la gâchette de glissière 36;
    • la commande de sélection 37 n'empêche pas le mouvement du levier de blocage 52 de façon à permettre de bloquer la gâchette de chien 28 lorsque la détente 5 est pressée.
On the other hand, the selection command 37 allows:
  • in the closed-breech shot mode position:
    • the slider trigger 36 is locked in an unobstructed position of the slider;
    • the blocking lever 52 is disengaged from the dog trigger 28 to allow free movement of the dog trigger 28;
  • in the open-breech mode shooting position:
    • the selection control 37 does not prevent the movement of the slide trigger 36;
    • the selection control 37 does not prevent the movement of the locking lever 52 so as to block the dog trigger 28 when the trigger 5 is pressed.

D'une manière générale on peut dire que l'invention concerne une arme qui comprend un mécanisme de percussion pour actionner un percuteur 10 permettant le tir semi-automatique et automatique ; une glissière 7; un mécanisme de gâchette de tir à culasse ouverte ou gâchette de glissière 36 permettant la retenue de la glissière 7 en position arrière ; un mécanisme d'activation de la gâchette de tir à culasse ouverte 36 et un mécanisme de synchronisation 43 entre le mécanisme de cette gâchette 36 et le mécanisme de percussion, l'interaction entre ces mécanismes permettant à l'arme de fonctionner de manière réversible en mode culasse fermée ou en mode culasse ouverte selon la position de la commande de sélection 37.In general, it can be said that the invention relates to a weapon which comprises a percussion mechanism for actuating a firing pin 10 allowing semi-automatic and automatic firing; a slide 7; an open-breech trigger mechanism or slider trigger 36 for retaining the slider 7 in the rear position; an open bolt trigger activation mechanism 36 and a synchronization mechanism 43 between the mechanism of this trigger 36 and the percussion mechanism, the interaction between these mechanisms allowing the weapon to function reversibly in breech mode closed or open breech mode according to the position of the selection command 37.

Il est évident que l'invention n'est nullement limitée à l'exemple décrit ci-avant mais que de nombreuses modifications peuvent être apportées à l'arme et au procédé décrits ci-avant sans sortir du cadre de l'invention.It is obvious that the invention is not limited to the example described above, but that many modifications can be made to the weapon and the method described above without departing from the scope of the invention.

Il n'est pas exclu par exemple de remplacer l'actuateur thermique par un autre type que celui décrit ci-avant ou même de s'abstenir d'un tel actuateur en dotant le système d'une commande manuelle laissant le choix au tireur de passer du mode de tir à culasse fermée au mode de tir à culasse ouverte et inversement. Un système électronique et mécanique mesurant la température de la chambre et actionnant la transition entre mode culasse ouverte ou culasse fermée quand cette température atteint une valeur définie est possible aussi par exemple.It is not excluded, for example, to replace the thermal actuator by a type other than that described above or even to refrain from such an actuator by providing the system with a manual control leaving the choice to the shooter. switch from closed-breech shooting mode to open-breech shooting mode and vice versa. An electronic and mechanical system measuring the temperature of the chamber and Actuating the transition between open cylinder head mode or cylinder head closed when this temperature reaches a defined value is also possible for example.

Le mécanisme de percussion pour actionner le percuteur 10 ne doit pas nécessairement comporter un chien mais peut être réalisé par un percuteur uniquement armé par un ressort et libéré par une gâchette. Le mécanisme de synchronisation sera alors prévu entre le mécanisme de percussion et la gâchette de glissière.The percussion mechanism for actuating the striker 10 need not include a dog but can be achieved by a striker only armed by a spring and released by a trigger. The synchronization mechanism will then be provided between the percussion mechanism and the slide trigger.
