Abstract (en)

[origin: DE19625565A1] The invention relates to a fuel supply pump for a fuel injection pump for internal combustion engines, with a driven pair of meshing pinions (7, 9) rotating in a pump chamber (3) or other rotary conveying components which feed the fuel from a suction chamber (13) connected to a tank along a supply channel (17) formed between the faces of the pinions (7, 9) and the peripheral wall of the pump chamber (3) to a pressure chamber (15) connected to the fuel injection pump, and with a by-pass channel (25), integrated into a housing (1) of the fuel supply pump and connecting the suction (13) and pressure (15) chambers, which can be controlled by means of a pressure valve (31) fitted therein, where the suction chamber (13) can be closed by a check valve (40) acting against the fuel supply device.
