ABSTRACT:
A fuel injection pump for supplying fuel to an internal combustion engine includes a pair of pumping plungers which are actuated by cam lobes formed on the internal periphery of an annular cam ring. Roller carrying shoes are interposed between the plungers and the cam lobes and are axially movable. The cam profile varies throughout its axial length so that variation in the axial setting of the shoes varies the amount of fuel supplied by the pump.
