摘要： The present invention relates to a high-pressure pump, particularly for delivering fuel for a common rail fuel injection system, having a pump body in which at least one cam drive having a cam shaft is received. The cam shaft is pivotally supported about a cam shaft axis in the pump body and/or in a flange body by at least one bearing arrangement. The bearing arrangement includes a radial bearing bush extending in the direction of the cam shaft axis, and an axial bearing washer, which is integrally formed on the radial bearing bush. The axial bearing washer extends in a radial extension direction of less than 90 degrees relative to the cam shaft axis in the non-installed state. The radial extension direction is directed toward the radial bearing bush and can be brought into an axial bearing plane extending at an angle of 90 degrees to the cam shaft axis in the installed state by elastic deformation of the axial bearing washer.

摘要： A pump unit for the metered delivery of fuel to internal combustion engines. The pump unit comprises a housing which comprises a longitudinal bore. Located in the longitudinal bore is an overflow valve, via which fuel flows back through a channel into a fuel tank. The passage can be opened or closed by a spring-loaded closing element. Fastened to the valve shaft of the overflow valve is a ring fitting. In the longitudinal bore of the housing there is an additional thread section, via which air flows out through vent gaps into a cavity of the ring fitting.

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： The invention relates to a high-pressure pump, especially for delivering fuel for a common rail fuel injection system. The pump includes at least one cam drive having a feeler element which can be set moving in direction of a stroke axis by a cam geometry introduced into the camshaft, the stroke movement being transmittable to a plunger unit. The plunger unit and the feeler element are impinged upon with a force by a compression spring element in the direction of the cam geometry and the plunger unit has at least one contact surface which adjoins the compression spring element. The at least one contact surface and/or the surface of the compression spring element adjoining the same has a friction-reduced surface coating to bring about a torsion decoupling of the compression spring element.

摘要： The invention provides for operation of camshafts, particularly for an injection pump for diesel. A camshaft rotates around a longitudinal axis of a camshaft. The camshaft has at least one cam being in cooperation with a pressure roller driven in a lifting manner. The pressure roller rotates on the peripheral surface of the cam. The upward stroke of the pressure roller is a working stroke during which the pressure roller moves away from the longitudinal axis of the camshaft. During a return stroke the pressure roller moves toward the longitudinal axis of the camshaft. The peripheral surface of the cam has a return stroke section and a working stroke section. The peripheral surface of the return stoke section has a greater friction value than the working stroke section. Thus an operation of camshafts for an injection pump for diesel is provided, securing a rotation of the pressure roller around the circumference of the cam within the whole speed range of the camshaft.

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.

摘要： The invention relates to a high pressure pump (1), which is used in particular as a radial or in-line piston pump for fuel injection systems of air-compressing auto-ignition internal combustion engines, comprising a pump assembly (13) and a drive shall (6) which comprises a cam (9) that is assigned to the pump assembly (13). The pump assembly (13) comprises a roller (25) which rolls with the roller surface (35) thereof on a running surface (10) of the cam (9). A rolling strength of the roller (25) on the roller surface (35) of the roller (25) and a rolling strength (9) of the running surface (10) of the cam (9) are specified as being identical. Under the highly dynamic stress of the cam (9) and the roller (25) during operation, this results in a critical threshold tension for both components (9, 25), which is equally critical for both components (9, 25).
