Abstract
A fuel injection pumping apparatus includes a piston movable to displace a pumping plunger to deliver fuel through an outlet. Fuel can be supplied to the bore containing the plunger from a pressure source. The piston is moved by liquid under pressure delivered by a cam actuated piston the liquid flowing into the cylinder containing the piston by way of a non-return valve. A spill port is provided to allow surplus liquid to escape from the cylinder. Following movement of the piston by the cam movement of the piston is initiated by closure of a valve. The same valve is utilized to control the return motion of the plunger after the delivery of fuel has stopped.
