Abstract
A rotary distributor type fuel pumping apparatus has an annular cam ring having internal cam lobes which impart inward movement to a pumping plunger as the distributor member is rotated. A piston is movable in a cylinder to vary the angular setting of the cam ring and the piston is coupled to the cam ring by means of a member having a gear tooth profile which is located in a recess in the piston. The member is integrally formed with a mounting having a pair of oppositely extending arms which are individually secured against mutually inclined flats on the periphery of the cam ring.
