摘要： The invention relates to an internal combustion engine comprising a high-pressure fuel pump (10) and a fuel injection valve (12) for a cylinder in the combustion engine. Said high-pressure fuel pump (10) comprises a working chamber (22) and the fuel injection valve (12) comprises an injection valve member (28) which controls at least one injection opening (32) and which can be displaced in the direction of the opening (29) counter to the force of a closing spring (44), whereby the closing spring (44) is supported by a injection valve member (28) and a displaceable accumulator piston (50), which is impinged upon by pressure produced in the working chamber (22) of the pump on the side facing away from the closing spring (44). Said accumulator piston (50) can be displaced counter to the force of the closing spring (44) into the accumulator chamber (54) and the alternative stroke of the piston (50) into the accumulator chamber (54) is limited by a stop (53). The accumulator piston (50) comprises a shaft section (64) having a small diameter arranged in an output position in a connecting bore (56) and a shaft section (63) having a larger diameter arranged outside the connecting bore (56) in the direction of the working chamber (22) of the pump. The shaft section (63) of the accumulator piston having a larger diameter plunges into the connecting bore (56) during the alternating stroke of the accumulator piston (50) when said piston moves into the accumulator chamber (54).

摘要： Soupape de limitation de pression pour un accumulateur haute pression d'un système d'injection de carburant de moteur. Elle comprend : un corps ayant un passage de régulation de pression (131) muni d'un piston (133) soumis à l'action d'un ressort taré (123) entre l'entrée de la soupape (131a) et sa sortie de retour (124) vers le réservoir (1). Le piston (133) s'ouvre vers le réservoir (1) lorsque la pression dans l'accumulateur (5) dépasse la pression de consigne. La soupape comporte en parallèle au passage de régulation (131), un passage d'équilibrage de volume (140, 140A) muni d'un clapet unidirectionnel (144) fermé par la pression dans l'accumulateur (5) et s'ouvrant par la dépression régnant dans l'accumulateur (5), vis-à-vis de l'extérieur.

摘要： The pump has a supporting unit (34) with a hollow cylindrical appendage (52) that is arranged at a pump body, where the appendage has a female thread area (54). The unit is screwed on a cylindrical boss (28) of the body, so that the area does not stand in contact with a male thread area (30) of the boss. The unit is movable with a pump piston (18) in a direction of a longitudinal axis of a cylinder borehole relative to the body.

摘要： The high pressure fuel pump has a pump piston defining a pump operating chamber (22) and driven by the internal combustion engine. the connection between the pump operating chamber and the balancing chamber is controlled by an electrically controlled valve. The fuel injection valve has a member controlling the at least one injection opening, and which is movable against the force of a closure spring into an opening direction. A collector piston (50) is movable into a storage chamber and is restricted by a stop. The piston has a shaft part (62) and a larger-cross-section part. A gap (68) between the shaft part and a connecting hole (56) dampens the piston's lift. The shaft part has a smaller (64) and a larger (63) cross-section part.
