摘要： The high-pressure pump has at least one pump element which has a pump plunger which is driven in a reciprocating motion and defines a pump working space into which fuel is drawn in from a fuel feed via an inlet valve during the suction stroke of the pump plunger and from which fuel is displaced into a high-pressure region via an outlet valve during the delivery stroke of the pump plunger. The inlet valve and/or the outlet valve has a valve member at least approximately in the shape of a ball which interacts by means of a sealing surface with a valve seat arranged in a valve housing. By means of the valve member, in the open state, when said valve member is lifted with its sealing surface from the valve seat, a first cross section of flow is cleared between the valve member and the valve seat, and downstream of the first cross section of flow, a second cross section of flow is formed between the valve member and the valve housing. In the direction of flow between the first cross section of flow and the second cross section of flow, a third cross section of flow is formed between the valve member and the valve housing, said third cross section of flow being larger than the first cross section of flow and the second cross section of flow.

摘要： A high-pressure pump has at least one pump element including a pump piston defining a work chamber and driven at least indirectly by a drive shaft in a reciprocating motion, counter to the force of a restoring spring. The pump piston is braced on the drive shaft at least indirectly via a sleevelike tappet, and the restoring spring engages at least the pump piston. A support element in the tappet braces the pump piston toward the drive shaft and is braced at least indirectly on the drive shaft. The restoring spring, via a spring plate, engages the pump piston and the tappet. The spring plate is elastically deformable in the direction of motion of the pump piston in such a way that as a result of its elastic deformation, deviations in the position of its contact faces on the pump piston and on the tappet are compensated for.

摘要： A high-pressure pump has at least one pump element, with a pump piston which is guided displaceably in a cylinder bore of a housing part of the high-pressure pump and is driven in a reciprocating motion and defines a pump work chamber in the cylinder bore, into which chamber fuel is aspirated via an inlet valve in the intake stroke of the pump piston. The inlet valve has a pistonlike valve member, which with a sealing face cooperates with a valve seat for controlling the communication of the pump work chamber with the fuel inlet. The valve member is disposed with a head, on which the sealing face is embodied, in the pump work chamber and protrudes out of the pump work chamber with a shaft adjoining the head. The valve seat is formed in the housing part at a transition from the cylinder bore to a bore of smaller diameter adjoining the cylinder bore. With its shaft, the valve member protrudes through the bore into a region of the housing part remote from the pump work chamber, in which region a closing spring is disposed that engages the shaft of the valve member.

摘要： A check valve having a valve housing inserted into a receptacle in which housing a pistonlike valve member is guided longitudinally displaceably and cooperating with a valve seat on the valve housing. The valve member is urged in the closing direction by a prestressed closing spring and in the opening direction by the pressure prevailing in an inlet, and the valve member is inserted into the valve housing from the side of the valve seat. The valve housing is embodied in one piece and is embodied as cup-shaped and has both a bottom and a jacket region that defines a recess. With the open end of its recess, the valve housing points out of the receptacle, and the valve seat is located on the bottom of the valve housing, facing away from the recess. With a shaft, the valve member protrudes through a bore in the bottom into the recess in which the closing spring is located.

摘要： The invention relates to a high-pressure fuel pump for a fuel injection system of an internal combustion engine, having a pump housing and with at least one pump element of a piston which is driven by a cam which interacts with a roller. The free ends of the roller are bounded by two side run-on surfaces which come into contact with mating surfaces during the operation of the high-pressure fuel pump. In order to provide a high-pressure fuel pump which can be produced cost-effectively and has a long service life, the side run-on surfaces are designed as circular ring disc surfaces and, in a central internal region, are released from contact with the mating surfaces.
