ABSTRACT:
A fuel injection pumping apparatus comprises a rotary distributor member which is also axially slidable within a fixed sleeve. The distributor member is provided with a recess which communicates with a bore containing the pumping plungers. The recess is provided with mutually inclined leading and trailing edges which cover and uncover inlet ports and outlet ports as the member rotates. While an inlet port is in communication with the recess fuel is allowed to flow to the bore and when the inlet ports are covered and outlet port is uncovered to the recess fuel flows from the bore to the uncovered outlet port. The fuel quantity is varied by altering the axial position of the distributor member.
