Abstract

L'invention concerne le raccordement de deux éléments montés l'un derrière l'autre coaxialement du système d'alimentation en carburant d'un moteur à combustion interne. Le premier élément est, de préférence, une douille réceptrice (3) destinée à loger une conduite de distribution de carburant (1) et comprenant une ouverture de guidage. Le second élément, qui se présente sous la forme d'une soupape de régulation de pression (8) ou d'un réducteur de pression, peut être inséré, par une partie de guidage (19), dans l'ouverture de guidage (18) de la douille réceptrice (3), laquelle comporte, dans une paroi (30), deux ouvertures de maintien (31) en vis-à-vis et alignées l'une par rapport à l'autre et par rapport à un écrou de fixation (37) se trouvant dans la soupape de régulation de pression (8). Un étrier de retenue (32) en forme de grand U s'insère, avec ses branches (34), dans ces ouvertures de maintien et bloque ainsi la douille réceptrice (3) et la soupape de régulation de pression (8) en position l'une par rapport à l'autre, ladite douille et ladite soupape présentant au moins dans la zone où repose l'étrier de retenue (32), des parties en acier inoxydable. Dans une variante, le premier élément peut être une soupape d'injection qui, par une de ses extrémités, est introduite dans un raccord à emmanchement (2) de la conduite de distribution de carburant (1), lequel forme le second élément, et est fixée dans ce raccord au moyen d'une pince de fixation. La soupape d'injection et le raccord à emmanchement (2) présentent, au moins dans la zone de la pince de fixation, des parties en acier inoxydable. Il est prévu, selon l'invention, que l'étrier de retenue (32) et que la pince de fixation soient, respectivement, constitués d'un fil pour ressort et d'un ruban pour ressort en acier inoxydable, cela pour éviter la corrosion due au contact.
