ABSTRACT:
A fuel pumping apparatus for supplying fuel to an internal combustion engine includes a plunger reciprocable within a bore having an outlet connected to an injection nozzle. The plunger is reciprocated through a fixed stroke and a valve is provided to close a spill path to start delivery of fuel to the nozzle. A movable piston controlled by an electrically operable valve, is allowed to move to absorb the fuel displaced by the plunger to halt fuel delivery to the nozzle.
