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.
