Abstract
A fuel pumping apparatus for supplying fuel to an internal combustion engine has a high pressure pump including a plunger reciprocable in a bore connected to a fuel injection nozzle. Valve means including a valve member and a piston member is provided. The valve member can be moved to a closed position to allow fuel flow to the nozzle and to prevent such flow an electromagnetic valve can be operated to allow displacement of the piston member. Movement of the piston member lowers the pressure of fuel supplied to the nozzle but also moves the valve member to the open position to allow the remaining fuel displaced by the piston to flow to a drain.
