ABSTRACT:
A rotary distributor fuel pumping apparatus has a spill valve which is operable to terminate delivery of fuel by a cam actuated pumping plunger. The spill valve is operable by a first piston and a further piston is provided the extent of movement of which is limited by an adjustable stop. A further plunger is actuated in synchronism with the pumping plunger and supplies liquid to the cylinders containing the pistons. When during the inward movement of the plungers, the movement of the further piston is halted the first piston will move to open the spill valve to terminate delivery of fuel.
