Title (EN) FUEL INJECTION PUMP
(FR) POMPE D'INJECTION DE CARBURANT
Abstract:
(EN) A reciprocating plunger fuel injection pump has a plunger (16) slidable in the bore (11) in a pump body (10). The plunger is biased outwardly by a spring (22) and moved inwardly by a cam. During the inward movement a port (13) in the bore is closed to allow pumping to commence. The outermost position of the plunger is determined by the engagement of a step (19) on the plunger with a divided stop plate (24) between which and the body is located a shim (27). The shim and stop plate are held in position by a cup shaped member (25) engaged with the body.
(FR) Une pompe d'injection de carburant à piston effectuant un mouvement alternatif comprend un piston (16) pouvant coulisser dans un passage (11) se trouvant dans un corps de pompe (10). Le piston est sollicité vers l'extérieur par un ressort (22) et tiré vers l'intérieur par une came. Au cours de ce mouvement vers l'intérieur, une ouverture (13) dans le passage est refermée afin de permettre au pompage de commencer. La position la plus externe du piston est déterminée lorsqu'un gradin (19) se trouvant sur le piston entre en contact avec une plaque d'arrêt (24) divisée, une rondelle de calage (27) étant située entre cette plaque d'arrêt et le corps. La rondelle de calage et la plaque d'arrêt sont retenues en position par un élément cupuliforme (25) vissé sur le corps.
