Abstract:
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.
