PCT No. PCT/GB93/00717 Sec. 371 Date Aug. 2, 1994 Sec. 102(e) Date Aug. 2, 1994 PCT Filed Apr. 6, 1993 PCT Pub. No. WO93/21438 PCT Pub. Date Oct. 28, 1993.A fuel pumping apparatus of the rotary distributor type has a pumping plunger (14) mounted in a bore (13) in the distributor member and a cam ring (24) operable to move the plunger inwardly in timed relationship with the associated engine. The cam ring is positioned by a fluid pressure operable piston (25) contained within a cylinder (26). The apparatus includes a further piston (31) mounted in a further cylinder connected to the first mentioned cylinder, the further piston being biased by a pre-stressed spring (32). A stop is provided to limit the movement of the further piston against the action of the spring which yields to limit the fuel pressure developed by the plunger during the initial inward movement.
