ABSTRACT:
A fuel injection pumping apparatus for supplying fuel to an internal combustion engine includes a rotary distributor member which is also axially movable to determine the amount of fuel supplied by the apparatus. Fluid under pressure is supplied to the chamber to move the distributor member axially against the action of a spring and valve means is provided to control the pressure. The valve means includes a first member in the form of a spool and a second member in the form of a sleeve. The sleeve is coupled by linkage to the distributor member and the position of the spool is determined by a speed responsive governor. A land on the spool co-operates with a port to control the flow of fluid to the chamber. A groove on the spool and a port register to allow fuel flow to a pumping chamber but move out of register to halt fuel flow if the spool should move with increasing speed without there being a corresponding movement of the distributor member and sleeve to reduce the fuel delivered by the apparatus.
