ABSTRACT:
A fuel injection pump of the rotary distributor type includes a pumping element movable in a bore to displace fuel from the bore to the injection nozzles of an engine in turn. A regulator controls the supply of fuel to the bore and is responsive to the speed of the engine and the setting of a control lever coupled to the accelerator pedal of a vehicle driven by the engine. The pump also includes valve means which is opened when the engine speed is above a predetermined value and the accelerator pedal has been released by the vehicle driver. The valve means when open prevents the supply of fuel to the engine and as the engine speed falls closes at a predetermined speed to restore the supply of fuel.
