Abstract
A rotary distributor fuel pumping apparatus includes a cam actuated pumping plunger which delivers fuel to a plurality of outlets in turn during successive inward movements. A spill valve is provided which can be opened when fluid pressure is applied to a piston to spill fuel from the bore. An auxiliary plunger delivers fluid under pressure which can be applied to the piston through a control valve. The control valve includes an annular spring loaded component which is moved by the fluid pressure and an angularly adjustable rod which is surrounded by the component. The rod is provided with a helical groove and the component with a slot and when these are brought into communication fluid under pressure is applied to the piston.
