Description
La présente invention concerne un injecteur de combustible, notamment pour un moteur à combustion interne.The present invention relates to a fuel injector, in particular for an internal combustion engine.
On connaît, notamment par le document US-A-3 777 984, un injecteur de combustible comprenant un corps sensiblement cylindrique, traversé par un conduit d'injection de combustible sensiblement parallèle à l'axe longitudinal du corps et comportant une entrée latérale de combustible ; le corps contenant successivement, de bas en haut, une aiguille d'injection prolongée d'un poussoir comprenant une tête recevant l'appui d'un ressort de rappel de fermeture précontraint à l'aide d'une vis de réglage, cette vis étant située sous l'entrée latérale de combustible.Is known, in particular from document US-A-3 777 984, a fuel injector comprising a substantially cylindrical body, traversed by a fuel injection conduit substantially parallel to the longitudinal axis of the body and comprising a lateral fuel inlet ; the body successively containing, from bottom to top, an injection needle extended from a pusher comprising a head receiving the support of a closing return spring prestressed using an adjusting screw, this screw being located under the side fuel inlet.
Mais dans ce type d'injecteur, l'entrée latérale de combustible n'est pas située dans la moitié inférieure du corps de sorte qu'il faut prévoir un conduit d'injection traversant pratiquement le corps sur toute sa longueur et ceci augmente inutilement le volume de combustible entre la sortie de la pompe d'injection et l'aiguille.However, in this type of injector, the lateral fuel inlet is not located in the lower half of the body, so that an injection pipe must pass through practically the entire length of the body, and this unnecessarily increases the volume of fuel between the injection pump outlet and the needle.
D'autre part, la vis de réglage est accessible par - une fente mais il faut prévoir un puits d'accès à cette fente et la manoeuvre de la vis manque alors de sûreté et de précision.On the other hand, the adjusting screw is accessible by - a slot but it is necessary to provide a well for access to this slot and the operation of the screw then lacks safety and precision.
La présente invention a pour but de remédier à ces inconvénients en plaçant l'entrée latérale de combustible dans la moitié inférieure du corps, et en incorporant un moyen de commande de la vis manoeuvrable de l'extérieur.The object of the present invention is to remedy these drawbacks by placing the lateral fuel inlet in the lower half of the body, and by incorporating a means for controlling the screw which can be operated from the outside.
A cet effet, la présente invention a pour objet un injecteur de combustible, notamment pour un moteur à combustion interne, du type comprenant un corps sensiblement cylindrique traversé par un conduit d'injection sensiblement parallèle à l'axe longitudinal dudit corps et comportant une entrée latérale de combustible, ledit corps contenant successivement, de bas en haut, une aiguille d'injection, un poussoir muni d'une tête, un ressort de rappel prenant appui sur la tête du poussoir une vis de réglage de la précontrainte du ressort située sous l'entrée latérale, caractérisé en ce que l'entrée latérale est située dans la moitié inférieure dudit corps et en ce que la vis de réglage est coaxialement solidaire d'un pignon mené engrenant avec un pignon menant coaxialement solidaire d'une tige de commande montée rotative dans le corps de l'injecteur et s'étendant jusqu'à l'extrémité supérieure de l'injecteur de façon à être manoeuvrable de l'extérieur.To this end, the subject of the present invention is a fuel injector, in particular for an internal combustion engine, of the type comprising a substantially cylindrical body traversed by an injection conduit substantially parallel to the longitudinal axis of said body and comprising an inlet lateral fuel, said body successively containing, from bottom to top, an injection needle, a pusher provided with a head, a return spring bearing on the head of the pusher a screw for adjusting the spring preload located under the side entry, characterized in that the side entry is located in the lower half of said body and in that the adjusting screw is coaxially secured to a driven pinion meshing with a driving pinion coaxially secured to a control rod rotatably mounted in the injector body and extending to the upper end of the injector so as to be operable from the outside.
L'invention sera mieux comprise, et d'autres buts caractéristiques, détails et avantages de celles-ci apparaîtront plus clairement au cours de la description explicative qui va suivre faite en se référant au dessin schématique annexé donné uniquement à titre d'exemple non limitatif dans lequel la figure unique est une coupe axiale de l'injecteur selon un mode de réalisation spécifique actuellement préféré de l'invention, avec un arrachement partiel montrant le dispositif d'amenée de combustible.The invention will be better understood, and other characteristic aims, details and advantages of these will appear more clearly during the explanatory description which follows, made with reference to the appended schematic drawing given solely by way of nonlimiting example. in which the single figure is an axial section of the injector according to a specific currently preferred embodiment of the invention, with a partial cutaway showing the fuel supply device.
L'amenée 1 de combustible, notamment pour un moteur à combustion interne, comprend un corps 2, sensiblement cylindrique, traversé par un conduit 15 d'injection de combustible, sensiblement parallèle à l'axe central longitudinal du corps 2, et comportant une entrée latérale 3 de combustible située dans la moitié inférieure du corps 2, sensiblement à mi-hauteur de celui-ci dans l'exemple représenté sur la figure annexée. Le corps 2 contient successivement, de bas en haut, une aiguille d'injection 4 prolongée d'un poussoir allongé 5 comprenant une tête 6 recevant l'appui d'un ressort 7 de rappel de fermeture précontraint à l'aide d'une vis de réglage 8.The fuel supply 1, in particular for an internal combustion engine, comprises a
Le corps 2 de l'injecteur 1 est disposé dans un fourreau 9 logé dans la culasse 10 ; les références 12 représentant les soupapes disposées de part et d'autre de l'injecteur sur leur siège respectif 13. Différents joints 29 sont en outre prévus entre la culasse 10, le fourreau 9 et le corps 2 de l'injecteur.The
L'aiguille d'injection 4, dont l'extrémité conique 18 repose, en position fermée de l'injecteur, sur un siège conique, commande, de façon classique, l'injection de combustible dans la chambre de combustion 16 par l'intermédiaire d'une buse 17 d'injection.The injection needle 4, whose
Le poussoir est suffisamment court, en direction longitudinale, pour que le niveau d'arrivée latérale de combustible soit situé au-dessus de l'extrémité supérieure de l'ensemble constitué par la vis de réglage 8, le ressort 7, le poussoir 5 et l'aiguille 4 d'injection placés en série.The pusher is short enough, in the longitudinal direction, so that the level of lateral fuel inlet is located above the upper end of the assembly constituted by the adjusting screw 8, the spring 7, the
Le poussoir 5 est sensiblement plus court que l'aiguille d'injection 4, la longueur du poussoir représentant par exemple environ un quart de celle de l'aiguille. On peut noter en outre que la longueur et le diamètre du poussoir 5 sont réduits, respectivement, à environ un dixième et à environ la moitié de la longueur et du diamètre d'un poussoir usuel.The
Dans le mode de réalisation représenté, le corps 2 de l'injecteur comprend une partie supérieure 20 où le conduit d'injection 15 est sensiblement parallèle à l'axe central longitudinal du corps 2. Le niveau d'arrivée latérale de combustible est situé sensiblement à mi-hauteur du corps de l'injecteur au-dessus de la vis de réglage 8, et le dispositif d'amenée de combustible comprend un conduit d'arrivée 35 relié par une vis d'assemblage 36 au conduit 15. Le corps 2 de l'injecteur comprend en outre une pièce intercalaire 21 entourant le corps 37 du poussoir 5 et une partie inférieure 23 où le conduit d'injection 15 est oblique et débouche dans une gorge annulaire 24. La pièce intercalaire 21 est percée d'un alésage 22 qui met en communication les deux parties du conduit d'injection situées dans les parties supérieure 20 et inférieure 23 du corps 2 de l'injecteur. La mise en place de la pièce intercalaire 21 est facilitée par un tenon de centrage 27. Les parties supérieure 20 et inférieure 23, ainsi que la pièce intercalaire 21 sont réunies par une pièce 26 enveloppant la partie inférieure 23, la pièce intercalaire 21 ainsi que l'extrémité inférieure de la partie supérieure 20, l'étanchéité à la base de cette pièce 26 étant assurée par un joint torique métallique 28.In the embodiment shown, the
D'autre part, la vis de réglage 8 est coaxialement solidaire d'un pignon mené 30 engrenant avec un pignon menant 31 coaxialement solidaire d'une tige de commande 32, montée rotative dans le corps 2 de l'injecteur 1, et s'étendant jusqu'à l'extrémité supérieure de l'injecteur de façon à être manoeuvrable de l'extérieur. Une goupille de blocage 33 de l'extrémité supérieure de la tige 32 de commande est prévue. Il est également prévu à l'extrémité supérieure du corps 2 de l'injecteur 1 une bride de serrage 34 de l'injecteur dans la culasse. Il est également prévu un canal 38 de retour des fuites de combustible traversant notamment la culasse 10, le fourreau 9 et le corps 2 de l'injecteur et débouchant dans le logement 39 de la tige de commande 32 dans le corps 2 de l'injecteur.On the other hand, the adjusting screw 8 is coaxially secured to a driven pinion 30 meshing with a driving
Le fonctionnement d'un injecteur de ce type est bien connu et sera indiqué brièvement ci-après. A chaque cycle d'actionnement de la pompe d'injection, une certaine quantité de combustible est refoulée sous pression dans le conduit d'injection 15 et pénètre dans la chambre annulaire 24. La pression du combustible engendre d'abord une force de poussée sur l'épaulement 25 de l'aiguille 4 ce qui a pour effet de soulever l'extrémité conique 18 de l'aiguille 4 de son siège 19. Une partie de combustible est alors chassée par la buse d'injection 17 dans la chambre de combustion 16. L'injection se poursuit tant que la pression du combustible s'exerçant sur l'épaulement 25 est suffisante pour vaincre la force du ressort 7 de rappel. Après quoi, l'aiguille est réappliquée sur son siège 19 et l'injection est arrêtée jusqu'au cycle suivant.The operation of an injector of this type is well known and will be briefly indicated below. At each actuation cycle of the injection pump, a certain amount of fuel is discharged under pressure into the
Néanmoins, le fait que le poussoir 5 est de longueur réduite et a donc une masse inerte relativement faible permet d'améliorer l'injection de combustible, et notamment d'éviter les perturbations au rebondissement de l'aiguille d'injection sur son siège qui se produisent avec un poussoir relativement lourd de type usuel.Nevertheless, the fact that the
On peut en outre facilement régler la force de rappel du ressort 7 en manoeuvrant, de l'extérieur, la tige de commande 32 qui commande la vis de réglage 8.One can also easily adjust the return force of the spring 7 by maneuvering, from the outside, the
