Abstract:
A fuel delivery pump for a fuel injection pump for internal combustion engines, comprising a pair of gears (7, 9), that mesh with each other and are driven to rotate in a pump chamber (3) in a housing (1), said gears (7,9) deliver fuel from an intake chamber (13) connected to a storage tank, along a supply conduit (17) that is formed between an end face of the gears (7, 9) and a circumference wall of the pump chamber (3), into a pressure chamber (15) connected to the fuel injection pump, a bypass conduit (25), which is integrated into the housing (1) of the fuel delivery pump and connects the intake chamber (13) to the pressure chamber (15), said bypass conduit is opened by means of a pressure valve (31) disposed in said bypass conduit, the pressure valve (31) is operationally connected to an axially aligned throttle valve (40, 50) that throttles the fuel delivery into the intake chamber (13) as a function of the controlled pressure on the pressure valve (31) via the pressure chamber (15).
