    摘要： A geared pump, having a housing (18), two gear wheels (14, 16) that are disposed in the housing and mesh with one another, and at least one groove (22) that is embodied in the housing on the pressure side of the geared pump, cavitation damage at high rpm is to be avoided. To that end, it is provided that the groove has a first portion (24), which extends from the pressure side, and in which the bottom of the groove (22) has a slight spacing from the tips of the teeth (20) of the gear wheel, and a second portion (26), which adjoins the first portion and in which the bottom of the groove (22) has a maximum spacing from the tooth tips that is greater than the spacing in the first portion, and the first portion extends over a smaller angular range (&agr;) than the second portion, and the groove extends over a total angular range (&agr;, &bgr;) that is somewhat greater than angular spacing between two teeth (20).

    摘要： A geared feed pump has a housing having a pump chamber in which a rotationally driven pair of gear wheels meshing with one another is disposed for pumping medium out of a suction chamber that communicates with a supply tank, along feed conduits, formed between the circumferential surface of the gear wheels and the circumferential walls of the pump chamber, into a pressure chamber. A drive shaft connected with one of the gear wheels via a coupling member is disposed inside the housing in a coupling chamber. The coupling chamber has a connection with the pressure chamber, so that lubrication of the coupling member is effected by the pumping medium.

    摘要： A fuel injection system having a fuel reservoir, a high-pressure fuel pump by which fuel is pumped into the fuel reservoir as a function of engine operating parameters, a prefeed pump by which fuel is pumped from a fuel tank to the intake side of the high-pressure fuel pump, a fuel metering device for adjusting the fuel quantity pumped into the fuel reservoir by the high-pressure fuel pump, and at least one injector, communicating with the fuel reservoir, for fuel injection to the engine. The metering device is disposed between the fuel tank and the intake side of the prefeed pump. The high-pressure fuel pump has a drive region, which for the sake of its lubrication can be made to communicate with the outlet of the prefeed pump, via a pressure valve that opens towards the drive region.
