ABSTRACT:
A fuel injection pumping apparatus comprises an axially movable distributor member the axial setting of which determines the amount of fuel supplied by the apparatus at each pumping stroke. The distributor member is biassed by a spring in one axial direction and is movable in the opposite direction by varying the fluid pressure in a chamber through a port. The port is formed in a sleeve which is coupled to the distributor member by means of a lever and a rod member is axially movable within the sleeve. The axial position of the rod member can be varied to alter the effective size of the port and the distributor member and sleeve move because of the change in pressure in the space. A new equilibrium position is thus established with the distributor member following the movement of the rod member.
