ABSTRACT:
A fuel injection pump for supplying fuel to an internal combustion engine includes a plunger reciprocable within a bore by cams on a cam ring. Fuel is supplied to the bore by a throttle. A first valve is provided which connects a point intermediate the throttle and the bore with a drain. A second valve is provided to ensure that the pressure applied to the outer end of the plunger is above said drain pressure. When the first valve is opened the pressure acting at the outer end of the plunger will move it inwardly to ensure that it cannot be actuated by the cam.
