Abstract

A fuel injection pump for an internal combustion engine includes a pair of reciprocable pumping plungers which are moved inwardly to effect a pumping stroke by means of rollers carried by shoes engaging the plungers, the rollers engaging cam lobes. A stop is provided which has end portions lying in the path of movement of the shoes and the surfaces of the shoes and end portions of the leaf stop are so shaped that when lateral movement is imparted to the shoes, the extent by which the shoes can move outwardly, will be varied.
