Description
La présente invention concerne un dispositif pour la fixation d'un injecteur de carburant sur une culasse de moteur à combustion interne.The present invention relates to a device for fixing a fuel injector on a cylinder head internal combustion engine.
On connaít de tels dispositifs de fixation selon lesquels une partie d'extrémité inférieure de l'injecteur est maintenue en appui, par l'intermédiaire d'une rondelle d'étanchéité non élastique généralement en cuivre, sur une face interne de la culasse perpendiculaire à l'axe longitudinal de l'injecteur par une bride comportant deux bossages opposés en appui respectivement sur deux méplats usinés du corps de l'injecteur.We know such fastening devices according to which a lower end portion of the injector is kept in support, by means of a washer non-elastic sealing generally made of copper, on an internal face of the cylinder head perpendicular to the axis longitudinal of the injector by a flange comprising two opposite bosses supported respectively on two flats machined from the injector body.
Cependant, ces dispositifs connus ne sont pas du tout adaptés pour des injecteurs compacts de petit diamètre, par exemple de 17 mm, sur lesquels il est quasiment impossible d'usiner les deux méplats d'appui de la bride.However, these known devices are not at all suitable for compact small diameter injectors, for example 17 mm, on which it is almost impossible to machine the two flange support flats.
On connaít également un autre dispositif de fixation selon lequel l'injecteur est serré dans la culasse par un écrou central en appui sur un jonc solidaire du corps de l'injecteur. Ce dispositif connu a pour inconvénient qu'il y a un risque de desserrage de l'écrou central à cause de dilatations thermiques différentes de l'injecteur et de la culasse et l'écrou central n'autorise pas de reprise élastique des efforts entre l'injecteur et la culasse lors de telles dilatations. Ainsi, il est nécessaire de serrer l'écrou central à un couple très élevé, mais un tel serrage risque d'écraser la rondelle d'étanchéité entre l'injecteur et la culasse de sorte que cette dernière risque de ne plus assurer sa fonction d'étanchéité.We also know another fixing device that the injector is tightened in the cylinder head by a central nut resting on a rod secured to the body the injector. This known device has the disadvantage that there is a risk of loosening the central nut at because of thermal expansions different from the injector and the cylinder head and the central nut does not allow elastic recovery of forces between the injector and the cylinder head during such expansions. Thus, it is necessary to tighten the central nut to a very high torque, but such tightening may crush the sealing washer between the injector and the cylinder head so that the latter may no longer ensure its sealing function.
Le document WO 87/00246 A montre un dispositif pour la fixation d'un injecteur sur une culasse de moteur à combustion interne. L'injecteur est maintenu engagé partiellement dans un logement cylindrique débouchant de la culasse par une bride s'appuyant, par le biais d'une bague, sur un épaulement. La bride est fixée à la culasse par deux vis. Elle contient deux ressorts à lame opposés tournés vers la culasse qui s'appliquent sur deux zones d'appui diamétralement opposées de l'injecteur.Document WO 87/00246 A shows a device for fixing an injector on a internal combustion engine cylinder head. The injector is kept partially engaged in a cylindrical housing opening from the cylinder head by a flange resting, by through a ring, on a shoulder. The flange is fixed to the cylinder head by two screws. It contains two opposite leaf springs facing the cylinder head which are applied to two diametrically opposite bearing zones of the injector.
Le document EP 0735 267 A (cité au titre de l'article 54(3) CBE) présente un autre dispositif fixant l'injecteur à la culasse au moyen d'une bride et deux vis. La bride prend appui au travers d'un manchon sur un anneau élastique placé dans un évidement au bas de l'injecteur.Document EP 0735 267 A (cited under Article 54 (3) EPC) presents another device fixing the injector to the cylinder head by means of a flange and two screws. The bridle is supported through a sleeve on an elastic ring placed in a recess at the bottom of the injector.
La présente invention a pour but d'éliminer les inconvénients ci-dessus des dispositifs connus en proposant un dispositif pour la fixation d'un injecteur de carburant sur une culasse de moteur à combustion interne, du type dans lequel l'injecteur est maintenu engagé partiellement dans un logement cylindrique débouchant de la culasse sur une face de celle-ci perpendiculaire à l'injecteur au moyen d'une bridé espacée de cette face et fixée à la culasse par deux vis traversant perpendiculairement cette face, deux bossages opposés de la bride, tournés vers cette face, étant appliqués sur deux zones d'appui au moins diamétralement opposées de l'injecteur et qui est caractérisé en ce que les zones d'appui sont réalisées dans un évidement débouchant sur la périphérie d'une portion cylindrique de l'injecteur et situé au dessus de la face de la culasse et recevant une pièce intermédiaire émergeant partiellement de l'évidement et en ce que chaque bossage de la bride, extérieur à la portion cylindrique de l'injecteur, est appliqué sur une partie émergente de la pièce intermédiaire.The object of the present invention is to eliminate the above disadvantages of devices known in proposing a device for fixing an injector fuel on a combustion engine cylinder head internal, of the type in which the injector is kept partially engaged in a cylindrical housing emerging from the cylinder head on one side thereof perpendicular to the injector by means of a flange spaced from this face and fixed to the cylinder head by two screws perpendicularly crossing this face, two bosses opposite of the flange, facing this face, being applied to two support zones at least diametrically opposite of the injector and which is characterized in that the support zones are made in a recess opening onto the periphery of a cylindrical portion of the injector and located above the face of the cylinder head and receiving an emerging intermediate piece partially of the recess and in that each boss of the flange, outside the cylindrical portion of the injector, is applied to an emerging part of the intermediate piece.
Selon un mode de réalisation de l'invention, l'évidement est une gorge périphérique et les deux zones d'appui sont reliées entre elles pour former une zone d'appui circulaire pour la pièce intermédiaire.According to one embodiment of the invention, the recess is a peripheral groove and the two support zones are interconnected to form a support area circular for the intermediate piece.
De préférence, la pièce intermédiaire est constituée d'un jonc en métal élastique.Preferably, the intermediate piece consists of a elastic metal band.
Selon une variante de réalisation, les deux bossages de la bride sont reliés entre eux en formant une base d'appui circulaire de la bride sur les deux zones d'appui de l'injecteur.According to an alternative embodiment, the two bosses of the flange are connected together forming a base circular support of the flange on the two support zones of the injector.
Avantageusement, une bague est interposée entre le jonc et la bride. Advantageously, a ring is interposed between the rod and the flange.
Selon une variante de réalisation, la bague comprend un chanfrein coopérant avec le jonc.According to an alternative embodiment, the ring comprises a chamfer cooperating with the rod.
Selon un autre mode de réalisation, chaque zone d'appui est réalisée dans un évidement radial constitué d'un trou borgne recevant un ergot d'appui d'un bossage correspondant de la bride.According to another embodiment, each support zone is made in a radial recess consisting of a hole blind receiving lug supporting a boss matching flange.

Le dispositif de fixation conforme à l'invention concilie un encombrement réduit et une bonne reprise élastique des efforts résultant des dilatations thermiques différentes de l'injecteur et de la culasse notamment grâce à l'utilisation des deux vis relativement longues de fixation de la bride, assurant ainsi une bonne tenue avec serrage modéré de l'injecteur et une excellente étanchéité puisque la rondelle d'étanchéité R ne risque plus d'être écrasée lors du serrage de l'injecteur par la bride 3.The fixing device according to the invention reconciles reduced dimensions and good elastic recovery of forces resulting from different thermal expansions injector and cylinder head, in particular thanks to the use of the two relatively long screws of fixing the flange, thus ensuring a good hold with moderate clamping of the injector and excellent sealing since the sealing washer R does not risk more to be crushed when tightening the injector by the flange 3.
