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.

A fuel injection pumping apparatus for supplying fuel to an internal combustion engine of the kind comprising a fluid pressure operable piston located within a cylinder, an outlet from one end of the cylinder, first valve means through which fuel can be admitted to said one end of the cylinder, a plunger reciprocable within a bore, an engine driven cam for actuating said plunger, a passage connecting one end of said bore with the other end of said cylinder, second valve means operable to allow fluid under pressure displaced from said bore during inward movement of said plunger by the cam, to flow to said other end of the cylinder thereby to displace the piston and cause fuel flow through the outlet, and means for sensing the relative angular movement of the cam and plunger during the period fuel is allowed to enter said one end of the cylinder, the angular movement of the cam being representative of the axial movement of the piston.
