Title (EN) FUEL INJECTION PUMP
(FR) POMPE D'INJECTION DE CARBURANT
Abstract:
(EN) A reciprocating plunger fuel injection pump has a plunger (17) slidable in a bore (16) in a body (10). A tubular part (34) surrounds the portion of the plunger projecting from the bore in spaced relationship. Slidable in the tubular part is an annular member (33) which is coupled to the plunger (17) and carries a spring abutment (36). Mounted on the tubular part (34) is an adjustable member (40) having in one example an inturned flange (41) engageable with a step (41A) defined on the annular member (33) to determine a so-called datum position.
(FR) Une pompe d'injection de carburant à piston à mouvement alternatif comprend un piston (17) pouvant coulisser dans un passage (16) se trouvant dans un corps (10). Une pièce tubulaire (34) entoure de manière espacée la partie du piston qui fait saillie à partir du passage. Un élément annulaire (33) pouvant coulisser dans la pièce tubulaire est accouplé au piston (17) et porte un élément de butée (36) de ressort. Un élément réglable (40) monté sur la partie tubulaire (34) présente, selon un exemple, un rebord (41) tourné vers l'intérieur pouvant prendre appui sur un gradin (41A) se trouvant sur l'élément annulaire (33) pour déterminer ce qu'on appelle une position de référence.
