ABSTRACT:
A fuel injection pumping apparatus comprises an injection pump including an angularly movable cam ring connected to a piston. Resilient means bias the piston against the action of a fluid pressure which varies in accordance with speed. A cam plate engages an abutment for the resilient means and is adjustable by means of a pivotal lever the setting of which is varied in accordance with the amount of fuel supplied by the apparatus thereby to vary the setting of the cam plate. The fulcrum for the lever is adjustable in accordance with the speed by means of a further piston responsive to said fluid pressure.
