ABSTRACT:
A fuel pumping apparatus has a fixed body in which is defined bores containing pumping plungers. The plungers are moved inwardly by cam lobes on a rotatable cam ring to displace fuel to an associated engine. The cam ring is provided with an annular extension within which is located a drive shaft. The drive shaft is coupled to the extension of the cam ring by means of a tongue and slot connection. The tongue is carried on a push member mounted in the drive shaft and movable by means of a piston and the tongue and slot are arranged so that as the piston moves, relative angular movement will take place between the drive shaft and cam ring.
