摘要： A fuel injection valve for internal combustion engines, having a valve body with a bore defined on its end toward the combustion chamber by a conical valve seat, with a valve needle disposed longitudinally displaceably in the bore and a sealing face with two sealing portions on its end toward the combustion chamber with the second conical face being disposed on the combustion chamber side of the first conical face. An annular groove extending between the conical faces has an end facing away from the combustion chamber which acts as a sealing edge upon contact of the valve sealing face with the valve seat. Recesses embodied in the valve seat and/or on the valve sealing face hydraulically connect the annular groove with a portion of the second conical face located on the combustion chamber side of the annular groove.

摘要： In a fuel injection valve having a valve body, which contains a movable injector needle, having an actuating part, which supports the injector needle and communicates with a control pressure chamber, and having a compensation chamber, which communicates with a compensation piston, a closing force that counteracts a dynamic opening force should be reliably exerted on the actuating part. To this end, a spring element that exerts a compensating force on the injector needle is disposed between the injector needle and the compensation piston.

摘要： The invention relates to a pump, particularly a high-pressure fuel pump, having a drive shaft, which includes a section that is eccentric to the rotational axis thereof and on which a ring is rotatably supported. The pump has at least one pump piston, which is directly supported on the ring via the piston base thereof, or via a support element and is driven in a stroke movement upon the rotational movement of the drive shaft. The ring has an at least approximately planar contact surface in the region of the support of the piston base or of the support element, and the support surface of the piston base or of the support element on the ring is greater than the cross-sectional surface of the shaft of the pump piston. The extension of the support surface of the piston base or of the support element in the tangential direction to the rotational axis of the drive shaft is greater than the extension thereof in the direction of the rotational axis of the drive shaft.
