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 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： In a fuel injection pump of the distributor type, a solenoid valve is provided in the distributor and the valve member of this solenoid valve is supported in an axial bore of the distributor and actuated by a magnet fixed to the housing in order to block the connection between a pump working space of the distributor-type injection pump and a relief space during an intended high-pressure injection phase. Inherent in its construction, a distributor of such a fuel injection pump has a certain axial play in its mounting and this has an effect on the actuating travel of the valve member in the distributor in relation to the fixed electromagnet. In order to avoid changes in the magnetic properties, which can arise due to this axial association, part of the magnetic circuit in the form of a magnet plate is displaceable together with the distributor, with the result that the position of an armature connected firmly to the valve member relative to this part of the magnet core, with which it forms the working air gap, does not change depending on the axial position of the distributor, and the magnetic properties of the solenoid valve are thus maintained irrespective of the axial position of the distributor.

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.
