Abstract
A fuel pumping apparatus for supplying fuel to an internal combustion engine is of the rotary distribution type in which the outward movement of pumping plungers is determined by stops, the axial position of the distribution member being adjustable to determine in conjunction with the stops the amount of fuel delivered by the apparatus. The plungers are actuated by cam lobes on a cam ring and two types of cam lobe are provided. One type of lobe provides the normal pumping action while the other type of lobe is shaped to provide an initial delivery of fuel by the apparatus in advance of the main quantity of fuel. The initial quantity can be varied by moving the cam ring angularly.
