Abstract
A fuel injection system for an internal combustion engine provided with a cylinder, a air of fluid pressure operable valve means to control the supply of pressure fluid to and allowing the escape of fluid from one end of the cylinder, with the valves operating at different pressures, a fluid pressure generator supplying the fluid pressure to the valves, an actuating piston in the cylinder, resilient means urging the actuating piston towards one end of the cylinder, with the actuating piston being moved against the action of the resilient means when fluid under pressure is admitted to one end of the cylinder, and a fuel pumping piston arranged to be operated by the actuating piston to displace fuel to an outlet.
