The geared feed pump has a housing (10, 12) in which a pump chamber (14) is formed, in which chamber a rotationally driven pair of gear wheels (16, 18) meshing with one another is disposed, which gear wheels pump a pumping medium out of a suction chamber (44) that communicates with a supply tank, along feed conduits (48), formed between the circumferential surface of the gear wheels (16, 18) and the circumferential walls of the pump chamber (14), into a pressure chamber (46). The geared feed pump has a drive shaft (30), which is connected in a rotationally engaged manner with one of the gear wheels (16) via a coupling member (40) disposed inside the housing (10, 11) in a coupling chamber (41). The coupling chamber (41) has a connection (32, 54, 56) with the pressure chamber (46), so that lubrication of the coupling member (40) is effected by the pumping medium. The geared feed pump is used to pump Diesel fuel from a supply tank to a fuel injection pump of a self-igniting internal combustion engine.
