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： 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).

摘要： A solenoid-valve-controlled fuel-injection pump for internal combustion engines, in particular diesel engines, has a solenoid valve, whose valve needle separates a high-pressure region from a low-pressure region, i.e. connects the high-pressure region and low-pressure region, in the pump housing, via a valve seat; the injection period being controlled by the opening of the solenoid valve. In addition, a low-pressure compensating piston situated in the low-pressure region is provided in order to compensate for pressure fluctuations in the low-pressure region. The exceptional feature is that the low-pressure compensating piston, which is positioned coaxially to the solenoid-valve needle, takes the form of a component part that is separate from the solenoid-valve needle. This ensures that the solenoid valve is opened unhindered and as rapidly as possible by the opening force exerted on the solenoid-valve needle by the electromagnet.

摘要： A fuel injection pump of the distributor type which has a reciprocatingly driven pump piston that is load-bearing in a rotating distributor shaft which pumps fuel out of a pump work chamber to various fuel injection valves via a distributor opening. To control the duration of high-pressure injection, an electrically actuated valve is provided with a valve member in a valve chamber that communicates with the pump work chamber and from a second valve chamber, communicates with a low-pressure region. To terminate the high-pressure injection, the valve member makes a communication between the two valve chambers, whereupon the outflow of the fuel stream is controlled by disposing a diameter constriction in the connecting line, thus reducing any tendency to cavitation.

摘要： A fuel injection pump for internal combustion engines which has a moving part supported in a housing bore and on its jacket face on one side, has an exit opening that is under high pressure, and whose bearing is improved by virtue of the fact that on the jacket face of the part or in the wall of the housing bore, at least one pressure compensation is provided. The compensation face is connected to a high pressure source, is disposed on a side of the jacket face of the part which side is remote from the exit opening, and is continuously covered by the wall of the housing bore. As a result, a compensation of the pressure action by means of the pressure field prevailing in the region of the exit opening occurs so that an improved, less damage-prone bearing is produced with a greater high pressure tightness of the moving part.

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 magnet coil which is disposed in a cup-shaped housing that has stub for carrying magnetic flux to a magnet armature; the positioning of the magnet coil inside this cup-shaped housing is defined by an insulation spray coating, and the magnet coil has contact terminals which protrude to the outside, having been spray-coated with insulation, through the bottom of the cup-shaped housing. The bottom of the cup-shaped housing also has a third opening, which is likewise filled by material and which offers an opportunity, during the spray-coating, of introducing a rodlike part to support the magnet coil.
