Abstract (en)
[origin: WO02086305A2] 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).
