<p>A rotary distributor type fuel pumping apparatus has an annular cam ring 19 having internal cam lobes 20 which impart inward movement to a pumping plunger as the distributor member 11 is rotated. A piston 21 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 24 having a gear tooth profile which is located in a recess 23 in the piston. The member 24 is integrally formed with a mounting 25 having a pair of oppositely extending arms 26 which are individually secured against mutually inclined flats 28 on the periphery of the cam ring. <IMAGE></p> |
