ABSTRACT:
A fuel pumping apparatus includes a roller which co-operates with cam lobes formed on the internal periphery of the cam ring to effect inward movement of a pumping plunger. The maximum outward movement of the pumping plunger is determined by stop members positioned to engage with the opposite ends of the roller. One of the stop members comprises a continuous ring having a contoured in a surface but the other stop member comprises a plurality of links which are pivotally mounted and the setting of which can be varied to determine the maximum effective outward movement of the plunger and thereby the maximum amount of fuel which can be supplied.
