A lower part of a receiving housing is equipped with an adaptation support element.

Description

Domaine de l'inventionField of the invention

La présente invention a pour objet un support de pistolet pour appareil distributeur monté dans une installation de distribution de carburant de type gaz de pétrole liquéfié (GPL) équipée d'organes de commande du transfert de carburant entre une cuve de stockage et le réservoir de véhicules automobiles.The present invention relates to a nozzle holder for dispensing apparatus mounted in a liquefied petroleum gas (LPG) type fuel distribution system equipped with fuel transfer control members between a storage tank and the vehicle tank. automobiles.

Ces organes de commande comportent essentiellement, outre les conduites nécessaires à l'acheminement du carburant, une pompe à liquide immergée ou non dans la cuve de stockage, un mesureur volumétrique de carburant notamment à pistons permettant de déterminer le volume de carburant délivré à un utilisateur, ainsi qu'un calculateur électronique central.These control members essentially comprise, in addition to the conduits necessary for conveying the fuel, a submerged or non-submerged liquid pump in the storage tank, a volumetric fuel meter in particular with pistons making it possible to determine the volume of fuel delivered to a user. , as well as a central electronic calculator.

Etat de la techniqueState of the art

Les supports de pistolet équipant classiquement les appareils distributeurs de carburant des stations-service comportent :

  • un corps de réception notamment fermé par un couvercle à l'une de ses extrémités ou extrémité arrière et ouvert à son extrémité opposée ou extrémité avant de façon à définir à sa partie interne un logement de réception de l'extrémité libre d'un pistolet distributeur,
  • un embout de montage fixé au corps de réception au niveau de son extrémité avant et muni d'une ouverture pour permettre l'introduction de l'extrémité libre du pistolet distributeur, ainsi que d'une embase externe permettant l'assemblage du support et de l'appareil distributeur, et
  • des moyens de détection sensibles à l'état d'absence ou de présence de l'extrémité libre du pistolet distributeur dans le logement de réception.
The gun supports conventionally equipping the fuel dispensing apparatus of the petrol stations comprise:
  • a receiving body in particular closed by a cover at one of its ends or rear end and open at its opposite end or front end so as to define at its inner part a receiving housing of the free end of a dispensing gun ,
  • a mounting tip attached to the receiving body at its front end and provided with an opening to allow the introduction of the free end of the dispensing gun, and an external base for the assembly of the support and of the dispensing apparatus, and
  • sensing means responsive to the state of absence or presence of the free end of the dispensing gun in the receiving housing.

Ces moyens de détection sont reliés aux organes de commande pour leur transmettre des signaux représentatifs de cet état de façon à leur permettre de commander automatiquement en retour la mise en route ou l'interruption du transfert de carburant.These detection means are connected to the control members to transmit signals representative of this state so as to enable them to automatically control the start or interruption of fuel transfer.

En d'autres termes, les moyens de détection permettent d'actionner les organes de commande dès qu'un utilisateur retire le pistolet de son support de sorte qu'il puisse commencer le remplissage du réservoir de son véhicule en manoeuvrant la poignée équipant ce pistolet, et arrêter la livraison de carburant dès que l'utilisateur replace le pistolet distributeur dans son support.In other words, the detection means can actuate the control members as soon as a user removes the gun from its support so that it can begin filling the tank of his vehicle by manipulating the handle on the gun , and stop the delivery of fuel as soon as the user places the dispensing gun in its holder.

Il est à noter que dans le cadre de cette description, les termes avant, arrière, supérieur, inférieur... se réfèrent au support de pistolet monté sur l'appareil distributeur.It should be noted that in the context of this description, the terms front, rear, upper, lower ... refer to the gun support mounted on the dispensing device.

L'invention concerne exclusivement des appareils distributeurs de GPL, et non des appareils distributeurs de carburants traditionnels de type essence ou diesel.The invention relates exclusively LPG dispensing devices, and not dispensing devices of conventional fuels of gasoline or diesel type.

De tels appareils doivent satisfaire à des normes de sécurité très strictes imposées par la métrologie légale du fait des propriétés spécifiques de ce carburant, et ne peuvent pas avoir des caractéristiques calquées sur celles des appareils distributeurs de carburants traditionnels.Such devices must meet very strict safety standards imposed by legal metrology because of the specific properties of this fuel, and can not have characteristics modeled on those of traditional fuel dispensing devices.

En effet, le GPL qui est essentiellement constitué d'un mélange de butane et de propane issu du raffinage du pétrole et du traitement du gaz naturel se distingue par une très faible viscosité et par un caractère inflammable et explosif très marqué.Indeed, LPG which consists essentially of a mixture of butane and propane from petroleum refining and natural gas treatment is distinguished by a very low viscosity and a very flammable and explosive character.

Par suite, les installations de distribution de GPL doivent être conçues de manière à éviter tout risque de fuites pouvant avoir des conséquences très graves.As a result, LPG distribution facilities must be designed to avoid any risk of leaks that could have very serious consequences.

Pour cette raison, il est essentiel d'éviter l'accumulation de vapeurs dans les appareils distributeurs et notamment la formation de surpressions à la partie interne du logement de réception du pistolet distributeur.For this reason, it is essential to avoid the accumulation of vapors in the dispensing devices and in particular the formation of overpressure at the inside of the receiving housing of the dispensing gun.

Il est de surcroît impératif d'exclure à ce niveau tout risque de contact de vapeurs de GPL et d'éléments électroniques de nature à créer des arcs électriques pouvant être sources d'inflammations ou d'explosions extrêmement dangereuses.It is also essential to exclude at this level any risk of contact with LPG vapors and electronic elements likely to create electric arcs that can be sources of ignition or extremely dangerous explosions.

Il est en conséquence impossible de transposer purement et simplement aux appareils distributeurs de GPL les caractéristiques des pistolets et des supports des pistolets des appareils distributeurs de carburants traditionnels.It is therefore impossible to purely and simply transpose to LPG dispensing devices the characteristics of the guns and gun holders of traditional fuel dispensing devices.

Les pistolets distributeurs de GPL et les supports de ces pistolets se distinguent donc obligatoirement par des caractéristiques propres.The LPG dispensing guns and the supports of these guns are therefore necessarily distinguished by their own characteristics.

Les pistolets distributeurs de GPL actuellement proposés sur le marché présentent en général les caractéristiques suivantes :

  • ils ont un embout plus court et plus large que l'embout des pistolets distributeurs de carburants traditionnels, même si ce dernier embout est équipé d'organes de récupération de vapeurs,
  • ils ont un embout droit, alors que l'embout des pistolets distributeurs de carburants traditionnels est coudé,
  • leur poignée n'est pas protégée par une garde, contrairement à la poignée des pistolets distributeurs de carburants traditionnels.
LPG dispensing guns currently on the market generally have the following characteristics:
  • they have a tip shorter and wider than the tip of the traditional fuel dispensing guns, even if the latter nozzle is equipped with vapor recovery organs,
  • they have a straight nozzle, while the tip of the traditional fuel dispensing guns is bent,
  • their handle is not protected by a guard, unlike the handle of traditional fuel dispensing guns.

Les supports de ces pistolets distributeurs de GPL doivent bien entendu présenter des caractéristiques adaptées.The supports of these LPG dispensing guns must of course have suitable characteristics.

Un problème spécifique aux appareils distributeurs de GPL est lié au fait que les fabricants proposent actuellement sur le marché de nombreux types de pistolets distributeurs qui présentent tous, malgré les caractéristiques propres susmentionnées, des formes et des dimensions différentes et auxquels correspondent des supports spécifiques qui ne sont pas interchangeables.A specific problem with LPG dispensing apparatus is that manufacturers currently offer on the market many types of dispensing guns, all of which, despite the aforementioned specific characteristics, have different shapes and sizes and to which specific supports which are not interchangeable.

Par suite, il est nécessaire d'équiper chaque appareil distributeur d'un support spécifique au type de pistolet distributeur choisi.Consequently, it is necessary to equip each dispensing device with a support specific to the type of dispensing gun chosen.

Cette nécessité est de nature à accroître dans une large mesure le coût des supports et de l'installation.This necessity is likely to increase to a large extent the cost of the supports and the installation.

But de l'inventionPurpose of the invention

La présente invention a pour objet de remédier à cet inconvénient en proposant un support de pistolet pour appareil distributeur de GPL, à usage universel, c'est-à-dire pouvant être adapté à n'importe quel type de pistolet, ce quelles que soient sa forme et ses dimensions, étant entendu que l'ensemble constitué par un tel support et le pistolet associé doit satisfaire aux impératifs susmentionnés.The object of the present invention is to remedy this drawback by proposing a gun holder for LPG dispensing apparatus, for universal use, that is to say that can be adapted to any type of gun, whatever its shape and its dimensions, it being understood that the assembly constituted by such a support and the associated gun must satisfy the aforementioned requirements.

Exposé et avantages de l'inventionDescription and advantages of the invention

Selon l'invention, un tel support de pistolet est caractérisé en ce que le logement de réception est équipé à sa partie inférieure d'au moins un élément support d'adaptation s'étendant sur la totalité de la longueur du corps de réception.According to the invention, such a gun support is characterized in that the receiving housing is equipped at its lower part with at least one adaptation support member extending over the entire length of the receiving body.

De tels éléments supports d'adaptation ont pour fonction de guider l'extrémité libre du pistolet distributeur au cours de son insertion dans le logement de réception et de permettre son maintien dans ce logement ainsi que le déplacement de l'aimant en position d'arrêt.Such adaptation support elements serve to guide the free end of the dispensing gun during its insertion into the receiving housing and to allow its retention in this housing as well as the displacement of the magnet in the off position. .

Ces éléments supports d'adaptation peuvent avantageusement être réalisés en un matériau plastique.These adaptation support elements may advantageously be made of a plastic material.

On peut toutefois également envisager d'utiliser à cet effet un matériau de classe M0 ou M1 pour l'inflammation.However, it is also possible to envisage using for this purpose a class M0 or M1 material for ignition.

La présence de ces éléments supports d'adaptation permet de diminuer dans une large mesure le coût du support de pistolet conconforme à l'invention dans la mesure où les pièces constitutives de celui-ci qui sont les plus complexes à réaliser peuvent faire l'objet d'une seule et unique production, et où seuls les éléments supports d'adaptation qui sont très simples à réaliser sont spécifiques à chaque type de pistolet.The presence of these adaptation support elements makes it possible to reduce to a large extent the cost of the conconforme gun support. to the invention to the extent that the constituent parts thereof that are the most complex to achieve can be the subject of a single production, and where only the adaptation support elements that are very simple to achieve are specific to each type of gun.

Il est par ailleurs à noter qu'en cas de fuite du pistolet distributeur, le gaz échappé peut entraîner une surpression à la partie arrière du logement de réception, ce qui peut provoquer un risque d'expulsion du pistolet hors de son support.It should also be noted that in the event of a leak of the dispensing gun, the escaped gas may cause an overpressure at the rear part of the receiving housing, which may cause a risk of the gun being expelled from its support.

Selon une caractéristique particulièrement avantageuse de l'invention permettant de remédier à cet inconvénient, l'embout de montage comporte une fine entaille d'évacuation à sa partie interne.According to a particularly advantageous feature of the invention to overcome this drawback, the mounting tip has a thin evacuation notch at its inner part.

Grâce à la présence de cette fine entaille, la totalité du gaz pouvant s'échapper du pistolet distributeur peut librement s'évacuer vers l'extérieur permettant ainsi d'exclure tout risque de surpression au niveau du couvercle du logement de réception ou encore tout risque d'expulsion du pistolet distributeur hors de ce logement.Thanks to the presence of this fine notch, all of the gas that can escape from the dispensing gun can freely escape to the outside thus making it possible to exclude any risk of overpressure at the receiving housing cover or any risk expulsion of the dispensing gun out of this housing.

Il est par ailleurs à noter que les moyens de détection équipant les supports de pistolet des appareils distributeurs de carburant sont en règle générale constitués par des capteurs électroniques montés à la partie interne du logement de réception.It should also be noted that the detection means equipping the gun holders of fuel dispensing devices are generally constituted by electronic sensors mounted to the inner part of the receiving housing.

Or, la présence de tels capteurs peut être source de danger dans le cas d'installations de distribution de GPL.However, the presence of such sensors can be a source of danger in the case of LPG distribution facilities.

En effet, le contact de vapeurs de GPL et d'éléments électroniques peut créer des arcs électriques pouvant entraîner des inflammations ou explosions.In fact, contact with LPG vapors and electronic elements can create arcing that can lead to ignition or explosions.

La présente invention a également pour objet de proposer un support de pistolet pour appareil distributeur de GPL de nature à remédier à ces inconvénients.Another object of the present invention is to propose a gun support for a LPG distributor device that will remedy these disadvantages.

Selon l'invention, un tel support de pistolet est caractérisé en ce qu'il est équipé de moyens de détection comportant :

  • un capteur sensible aux variations du champ magnétique, relié aux organes de commande et fixé à la périphérie externe du corps de réception, et
  • un aimant monté mobile dans le logement de réception entre d'une part une position de transfert de carburant et d'autre part une position d'arrêt.
According to the invention, such a gun support is characterized in that it is equipped with detection means comprising:
  • a sensor responsive to variations of the magnetic field, connected to the control members and fixed to the outer periphery of the receiving body, and
  • a magnet mounted movably in the receiving housing between a fuel transfer position on the one hand and a stopping position on the other hand.

Selon l'invention, le capteur peut être du type électromécanique ou électronique (effet Hall).According to the invention, the sensor may be of the electromechanical or electronic type (Hall effect).

Cet aimant est automatiquement rappelé en position de transfert de carburant en l'absence de pistolet distributeur dans le logement de réception, c'est-à-dire lorsqu'un utilisateur retire le pistolet distributeur de son support pour remplir le réservoir de son véhicule.This magnet is automatically recalled in the fuel transfer position in the absence of dispensing gun in the receiving housing, that is to say when a user removes the dispensing gun from its support to fill the tank of his vehicle.

L'aimant est en revanche automatiquement déplacé vers la position d'arrêt lorsque l'utilisateur réintroduit le pistolet distributeur dans le logement de réception après avoir achevé le remplissage du réservoir de son véhicule.The magnet is however automatically moved to the stop position when the user re-enters the dispensing gun in the receiving housing after completing the filling of the tank of his vehicle.

Dans cette dernière position, l'aimant est situé à proximité immédiate du capteur dont il n'est séparé que par la paroi périphérique du corps de réception, ce qui permet de commander l'interruption du transfert de carburant suite à la variation du champ magnétique générée par la présence de l'aimant.In this latter position, the magnet is located in the immediate vicinity of the sensor from which it is separated only by the peripheral wall of the receiving body, which makes it possible to control the interruption of the fuel transfer following the variation of the magnetic field. generated by the presence of the magnet.

L'une des caractéristiques essentielles du support de pistolet conforme à l'invention est ainsi liée à l'utilisation d'un capteur sensible aux variations du champ magnétique qui est monté à l'extérieur du corps de réception cylindrique, donc à l'extérieur du logement de réception de sorte qu'il ne puisse pas y avoir de contact entre ce capteur et le carburant.One of the essential characteristics of the gun support according to the invention is thus related to the use of a sensor responsive to variations in the magnetic field which is mounted outside the cylindrical receiving body, therefore outside. receiving housing so that there can be no contact between this sensor and the fuel.

Un tel montage permet ainsi d'éviter les risques d'inflammation et d'explosion dus à la création d'arcs électriques.Such an arrangement thus avoids the risk of ignition and explosion due to the creation of arcing.

De plus, dans cette position, le capteur ne peut pas venir en contact avec le pistolet distributeur, ce qui permet d'exclure tout phénomène électrostatique pouvant être de nature à enflammer le carburant consécutivement à un tel contact.In addition, in this position, the sensor can not come into contact with the dispensing gun, which makes it possible to exclude any electrostatic phenomenon that may be of a nature to ignite the fuel as a result of such contact.

Il est à noter que conformément à l'invention, l'aimant doit être calibré de sorte que le champ magnétique détecté par le capteur ait une intensité entraînant la transmission d'un signal de commande de l'interruption du transfert de carburant lorsque le pistolet est totalement inséré dans le logement de réception.It should be noted that according to the invention, the magnet must be calibrated so that the magnetic field detected by the sensor has an intensity causing the transmission of a control signal of the interruption of the transfer of fuel when the gun is fully inserted into the receiving slot.

Selon une caractéristique préférentielle de l'invention, le corps de réception est équipé à sa partie interne et au niveau de sa génératrice supérieure d'une rainure longitudinale, de préférence traversante, dans laquelle l'aimant vient se loger en position d'arrêt.According to a preferred feature of the invention, the receiving body is equipped at its inner portion and at its upper generatrix with a longitudinal groove, preferably through, in which the magnet is housed in the stop position.

Cette rainure a plusieurs fonctions dont les principales consistent à permettre de rétracter l'aimant en position d'arrêt pour qu'il n'entrave pas l'introduction de l'extrémité libre du pistolet distributeur dans le logement de réception et à réduire l'épaisseur de la paroi de ce logement, donc la distance séparant l'aimant du capteur dans cette position.This groove has several functions, the main ones consist in allowing to retract the magnet in the off position so that it does not hinder the introduction of the free end of the dispensing gun into the receiving housing and reduce the wall thickness of this housing, therefore the distance separating the magnet from the sensor in this position.

La rainure longitudinale permet parallèlement de recueillir une grande partie du gaz échappé en cas de fuite du pistolet distributeur, diminuant ainsi le risque de surpression à la partie arrière du logement de réception.The longitudinal groove in parallel allows to collect a large part of the escaped gas in case of leakage of the dispensing gun, thus reducing the risk of overpressure at the rear portion of the receiving housing.

Selon une autre caractéristique de l'invention l'entaille d'évacuation est située dans le prolongement de la rainure longitudinale du corps de réception.According to another characteristic of the invention the evacuation notch is located in the extension of the longitudinal groove of the receiving body.

Selon une autre caractéristique de l'invention, l'aimant est logé dans un boîtier se prolongeant par une patte articulée à son extrémité libre autour d'une tige fixée sur le boîtier perpendiculairement à la rainure longitudinale, de part et d'autre de cette rainure.According to another characteristic of the invention, the magnet is housed in a housing extending by a tab articulated at its free end around a rod fixed on the housing perpendicular to the longitudinal groove, on either side of this groove.

L'aimant est ainsi suspendu à la tige autour de laquelle il peut librement pivoter et est automatiquement rappelé en position de transfert de carburant sous l'action de sa gravité en l'absence de contrainte s'exerçant sur lui.The magnet is thus suspended from the rod around which it can freely rotate and is automatically recalled in the fuel transfer position under the action of its gravity in the absence of stress exerted on him.

En revanche, lorsqu'un utilisateur introduit le pistolet distributeur dans le logement de réception, après avoir terminé le remplissage du réservoir de son véhicule, l'extrémité libre de celui-ci repousse l'aimant jusqu'à sa position d'arrêt dans laquelle il est rétracté dans la rainure longitudinale.On the other hand, when a user introduces the dispensing nozzle into the receiving housing, after completing filling of the tank of his vehicle, the free end thereof pushes the magnet back to its stop position in which it is retracted into the longitudinal groove.

Description d'un mode de réalisation de l'inventionDescription of an embodiment of the invention

Selon les figures 1 et 2, le support de pistolet 1 est essentiellement constitué d'un corps de réception cylindrique 2 d'axe horizontal et d'un embout de montage 4.According to Figures 1 and 2 , the gun support 1 essentially consists of a cylindrical receiving body 2 of horizontal axis and a mounting bit 4.

Le corps de réception 2 est fermé à son extrémité arrière par un couvercle 3 fixé au moyen de quatre vis 3a, et est ouvert à son extrémité avant de façon à définir à sa partie interne un logement de réception 2a de l'extrémité libre d'un pistolet distributeur 100 représenté sur les figures 3a à 3d.The receiving body 2 is closed at its rear end by a cover 3 fixed by means of four screws 3a, and is open at its front end so as to define at its inner part a receiving housing 2a of the free end of a dispensing gun 100 represented on the Figures 3a to 3d .

Le corps de réception 2 est muni sur sa périphérie externe et au niveau de son extrémité avant d'un filetage 2b sur lequel est vissé l'embout de montage 4.The receiving body 2 is provided on its outer periphery and at its front end with a thread 2b on which is screwed the mounting end 4.

Cet embout 4 est équipé d'une ouverture circulaire médiane 4a de diamètre correspondant à celui du logement de réception 2a et située dans le prolongement de ce logement pour permettre l'introduction de l'extrémité libre du pistolet distributeur 100 (figures 3a à 3d).This nozzle 4 is equipped with a median circular opening 4a of diameter corresponding to that of the receiving housing 2a and located in the extension of this housing to allow the introduction of the free end of the dispensing gun 100 ( Figures 3a to 3d ).

L'embout 4 est en outre équipé sur sa périphérie d'une embase externe 4b qui permet la fixation du support 1 à un appareil distributeur de carburant au moyen de vis non représentées sur les figures.The tip 4 is further equipped on its periphery with an external base 4b which allows the attachment of the support 1 to a fuel dispenser apparatus by means of screws not shown in the figures.

Selon les figures 1 et 2, un plateau 2c est usiné sur la périphérie externe du corps de réception 2 à la partie supérieure de ce corps.According to Figures 1 and 2 a plate 2c is machined on the outer periphery of the receiving body 2 at the upper part of this body.

Un capteur 5 sensible aux variations du champ magnétique est fixé sur le plateau 2c au moyen de deux vis 7.A sensor 5 sensitive to variations in the magnetic field is fixed on the plate 2c by means of two screws 7.

Le capteur 5 est par ailleurs relié au moyen d'un câble 6 à des organes de commande du transfert de carburant entre une cuve de stockage et le réservoir de véhicules automobiles qui ne sont pas représentés sur les figures.The sensor 5 is also connected by means of a cable 6 to control members of the fuel transfer between a storage tank and the tank of motor vehicles which are not shown in the figures.

Le corps de réception 2 est également équipé à sa périphérie interne d'une rainure longitudinale traversante 2d usinée au niveau de sa génératrice supérieure.The receiving body 2 is also equipped at its inner periphery with a longitudinal through groove 2d machined at its upper generatrix.

Cette rainure longitudinale 2d se prolonge vers l'extérieur au niveau de l'embout de montage 4 par une fine entaille d'évacuation 4c non représentée sur les figures 1 et 2 mais visible sur les figures 3a à 3d.This longitudinal groove 2d extends outwardly at the mounting end 4 by a fine evacuation notch 4c not shown on the Figures 1 and 2 but visible on Figures 3a to 3d .

Selon la figure 2, le corps de réception 2 est en outre équipé d'une tige 8 introduite dans des ouvertures traversantes usinées à la partie supérieure de ce corps de part et d'autre de la rainure longitudinale 2d et maintenue par un écrou 8a.According to figure 2 , the receiving body 2 is further equipped with a rod 8 inserted into through openings machined at the upper part of this body on either side of the longitudinal groove 2d and held by a nut 8a.

Cette tige 8 qui s'étend perpendiculairement à la rainure longitudinale 2d constitue un axe de pivotement pour une patte 9a articulée sur celle-ci à l'une de ses extrémités et portant à son extrémité opposée un boîtier 9 dans lequel est logé un aimant 10.This rod 8 which extends perpendicularly to the longitudinal groove 2d constitutes a pivot axis for a tab 9a hinged thereto at one of its ends and carrying at its opposite end a housing 9 in which is housed a magnet 10 .

Le mode de fonctionnement du support 1 sera décrit ci-dessous en se référant aux figures 3a à 3d.The operating mode of medium 1 will be described below with reference to Figures 3a to 3d .

Selon la figure 3a, en l'absence de pistolet distributeur 100 dans le logement de réception 2a du corps de réception 2, l'aimant 10 fait librement saillie à la partie interne de ce logement dans une position de transfert de carburant dans laquelle il est maintenu sous l'action de sa gravité.According to figure 3a , in the absence of a dispensing gun 100 in the receiving housing 2a of the receiving body 2, the magnet 10 is freely protruding from the inner part of this housing in a fuel transfer position in which it is held under the action of its gravity.

Dans cette position, les organes de commande sont en veille de façon à pouvoir déclencher le transfert de carburant si un utilisateur manoeuvre la poignée 101 du pistolet distributeur 100.In this position, the control members are in standby so as to be able to trigger the transfer of fuel if a user maneuvers the handle 101 of the dispensing gun 100.

Selon la figure 3b, lorsque, après avoir achevé le remplissage du réservoir de son véhicule, un utilisateur introduit le pistolet distributeur 100 dans le logement de réception 2a du corps de réception 2, l'extrémité libre de ce pistolet repousse l'aimant 10 ainsi que le boîtier 9 et la patte 9a qui se déplacent ainsi vers l'arrière en rotation autour de la tige 8.According to figure 3b when, after completing the filling of the tank of his vehicle, a user introduces the dispensing gun 100 in the receiving housing 2a of the receiving body 2, the free end of this gun pushes the magnet 10 and the housing 9 and the tab 9a which thus move backwards in rotation around the rod 8.

Selon la figure 3c, cette rotation autour de la tige 8 se poursuit et l'aimant 10 pénètre dans la rainure longitudinale 2d.According to figure 3c this rotation around the rod 8 continues and the magnet 10 enters the longitudinal groove 2d.

Selon la figure 3d, lorsque l'extrémité libre du pistolet distributeur 100 parvient en fin de course et est totalement insérée dans le logement de réception 2a, l'aimant 10 est rétracté dans la rainure longitudinale 2d en position d'arrêt.According to figure 3d when the free end of the dispensing gun 100 reaches the end of stroke and is fully inserted into the receiving housing 2a, the magnet 10 is retracted into the longitudinal groove 2d in the off position.

Dans cette position, l'aimant 10 est situé au voisinage immédiat du capteur 5 au-dessous de celui-ci et n'est séparé de ce capteur que par la paroi du corps de réception 2 qui est très mince à ce niveau compte tenu de l'usinage de la rainure longitudinale 2d.In this position, the magnet 10 is located in the immediate vicinity of the sensor 5 below it and is separated from this sensor only by the wall of the receiving body 2 which is very thin at this level given the the machining of the longitudinal groove 2d.

Dans cette position, le capteur 5 est sensible à la présence de l'aimant 10 qui a été calibré en conséquence et transmet alors aux organes de commande via le câble 6 des signaux de nature à mettre ces organes en arrêt pour interrompre tout transfert de carburant entre la cuve de stockage et le pistolet distributeur.In this position, the sensor 5 is sensitive to the presence of the magnet 10 which has been calibrated accordingly and then transmits to the control members via the cable 6 signals of such a nature to put these organs in stop to interrupt any transfer of fuel between the storage tank and the dispensing gun.

A partir de cette position d'arrêt, lorsqu'un nouvel utilisateur veut remplir le réservoir de son véhicule et extrait le pistolet distributeur 100 du logement de réception 2a, l'aimant 10 est automatiquement rappelé vers la position de transfert de carburant représentée sur la figure 3a sous l'action de sa gravité.From this stop position, when a new user wants to fill the tank of his vehicle and extracts the dispensing gun 100 from the receiving housing 2a, the magnet 10 is automatically recalled to the fuel transfer position shown on the figure 3a under the action of its gravity.

Le capteur 5 n'est alors plus sensible à la présence de l'aimant 10 et les organes de commande sont à nouveau mis en veille de façon à pouvoir déclencher le transfert de carburant dès que l'utilisateur actionne la poignée 101 du pistolet distributeur 100.The sensor 5 is then no longer sensitive to the presence of the magnet 10 and the control members are again put on standby so as to trigger the transfer of fuel as soon as the user actuates the handle 101 of the dispensing gun 100 .

Selon les figures 4a et 4b, le logement de réception 4a du corps de réception 2 est équipé à sa partie inférieure d'un élément support d'adaptation 200 s'étendant sur la totalité de sa longueur.According to Figures 4a and 4b , the receiving housing 4a of the receiving body 2 is equipped at its lower part with an adapter support member 200 extending over its entire length.

Le support 1 est ainsi adapté à la réception ou au guidage de l'extrémité libre d'un pistolet distributeur 110 de dimension inférieure au pistolet 100 représenté sur les figures 3a à 3d.The support 1 is thus adapted to receiving or guiding the free end of a smaller dispensing nozzle 110 to the gun 100 shown in FIGS. Figures 3a to 3d .

Selon la figure 5, l'élément support d'adaptation monobloc 200 est remplacé par deux éléments 210 fixés de part et d'autre du logement de réception 2a.According to figure 5 , the one-piece adapter support member 200 is replaced by two elements 210 fixed on either side of the receiving housing 2a.

Les éléments d'adaptation 200, 210 sont dimensionnés selon le type de pistolet (forme et dimensions) destiné à être accueilli dans le corps de réception 2 du support 1.The adaptation elements 200, 210 are sized according to the type of gun (shape and dimensions) intended to be accommodated in the receiving body 2 of the support 1.
