Abstract
A fuel pumping apparatus for supplying fuel to an internal combustion engine comprises a rotary distributor member mounting a pumping plunger slidable in a bore and moved inwardly to discharge fuel from the bore by cam lobes on the internal surface of a cam ring, the cam lobes acting on the plunger through a cam follower. A valve is provided which at a predetermined position during the inward movement of the plunger, is opened to lower the pressure in the bore and thereby to terminate fuel flow through an outlet. The valve is actuated by the cam lobes either from the cam follower or from the plunger.
