Abstract (en)
[origin: WO9749916A1] 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) 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, in which there is a channel (26) connecting the suction chamber (13) to the pressure chamber (15) which can be connected to a venting device (28), and upstream and downstream of the venting device (28) there is a pressure valve (33, 38) for a directional flow in the channel (26).
