Abstract

A fuel injection pump comprises a fluidpressure actuated piston 7, in contact with an injection piston 5. The quantity of fuel supplied to the cylinder 6 is regulated by an electrically actuated valve 3 which is controlled by an electronic device 12 in accordance with an engine condition. As shown the cylinder of the actuating piston 7 is connected in the required sequence to the feed pump 2 and the supply tank 1 by a valve 10 driven by the engine. The cylinder may alternatively be directly connected to the engine cylinder. For multi-cylinder engines a plurality of units may be employed or single units 10, 3, 6 may be used in conjunction with distributors. The intermediate chamber 15 is connected to the tank 1 and also forms a hydraulic stop for the piston 7.
