ABSTRACT:
A fuel pumping apparatus for supplying fuel to a multi-cylinder internal combustion engine includes a high pressure pump which supplies fuel in timed relationship with the engine. The fuel is distributed to fuel outlets in turn by means of an axially movable distributor member which has a groove connected to the high pressure pump and which can register with ports connected to the fuel outlets respectively. The distributor member is actuated by a lever means mounting rollers which engage cam profiles on a cup-shaped cam. The cam profiles are arranged such that the groove dwells at each port during the time fuel flows through the groove and port.
