ABSTRACT:
A fuel injection pumping apparatus includes a pair of plungers which are reciprocable within a bore formed in a rotary distributor member. The apparatus is required to provide fuel for a five cylinder engine and surrounding the distributor member is a cam ring which has five equiangularly spaced inwardly extending cam lobes. One of the plungers is engaged by a shoe which mounts a roller for engagement with the cam lobes in turn whilst the other plunger is engaged by a member which mounts a pair of rollers which are spaced by an amount such that they will engage at the same time, an adjacent pair of cam lobes. In this manner both plungers are moved inwardly at the same time five times at each revolution of the distributor member.
