Abstract
A fuel injection pumping apparatus for supplying fuel to an internal combustion engine includes a cylinder in which is located a fluid pressure operable piston. An outlet extends from one end of the cylinder and a valve controls the flow of fuel to the one of the cylinder from a fuel source. Also provided is an engine driven cam for actuating a plunger reciprocable in a bore. A second valve controls fluid flow from the bore to the other end of the cylinder and the valve is controlled by an electromagnetic actuator. Transducer means responsive to the position of the cam provides signals to control the actuator, the amount of fuel which flows into the one end of the cylinder being represented by the angular movement of the cam.
