Abstract

Selon l'invention un boulon mécanique à bout pointeau (53) est monté dans un trou de montage (48) formé dans un espaceur (45) définissant un espace d'injection de carburant (46). Le trou de montage (48) s'ouvre dans la surface de paroi intérieure (51) et la surface de paroi extérieure (49) de l'espaceur (45). Le boulon mécanique à bout pointeau (53) peut être fixé et détaché au travers de l'ouverture sur le côté de surface de paroi extérieure (49) de l'espaceur (45). Un gicleur (58) est disposé dans une partie du trou de montage (48) enfoncée par rapport à la surface de paroi intérieure (51) de l'espaceur (45). Du carburant (37) est alimenté depuis l'extérieur de l'espaceur (45) et introduit dans le trou de montage (48) par l'intermédiaire d'un passage de carburant (57) formé dans le boulon mécanique à bout pointeau (53), ledit carburant étant ainsi injecté à partir d'un trou d'injection ouvert en continu (59) du gicleur (58). Le gicleur (58) est fixé sur un axe (54) du boulon mécanique à bout pointeau (53) par ajustement serré, le trou d'injection (59) étant en communication avec le passage de carburant (57).
