ABSTRACT:
A fuel injection pumping apparatus comprises piston means slidable in a bore from one end of which extends a fuel outlet for connection to a nozzle. A fuel inlet is connected to the one end of the bore and a valve controls flow through the inlet into the bore. The piston means is actuated by liquid under pressure supplied by a plunger actuated by an engine driven cam located in a cylinder. A two way valve is provided to control flow of liquid from the cylinder either to the bore or to a source of liquid, the valve being controlled by an electrically operated actuator. The actuator is controlled by a control circuit which receives a signal from a transducer associated with the piston means.
