ABSTRACT:
A fuel injection pumping apparatus comprises a rotary distributor member mounting a pumping plunger in a transverse bore. A cam ring is provided to impart inward movement to the plunger as the distributor member rotates and the cam ring is movable angularly in accordance with speed by a fluid pressure operable device. Stop rings are mounted on the opposite sides of the cam ring and these are angularly adjustable to alter the allowed outward movement of the plunger. The stop rings are connected by a bridging member mounting a peg. The peg mounts a lever having a cam surface engageable with a stop member and the lever is movable by means of the cam ring so that the setting of the stop rings varies with speed.
