Abstract: A rotary distributor fuel pumping apparatus for supplying fuel to an internal combustion engine has a pair of pumping plungers housed in a diametrical bore formed in the distributor member. The plungers at a predetermined position during their inward movement open a spill path to terminate delivery of fuel through an outlet. The one plunger defines a plunger bore and the other plunger has an integral piston slidable therein. The piston has a relieved portion adjacent the other plunger which with the wall of the plunger bore forms a flow path from the pumping chamber the flow path communicating with a port at a predetermined position during the inward movement. The pumping chamber is of annular form and is defined between the plungers and the wall of the bore in the distributor member and the piston.

Abstract: A rotary distributor type fuel injection pump has a pair of angularly adjustable stop rings having shaped internal surfaces which can engage with the cam followers of the pump to limit the outward movement of the pump plungers. The stop rings are interconnected by a saddle member and a spring biases the saddle member into engagement with a stop. The stop which may be adjustable determines the normal maximum amount of fuel which can be supplied by the pump. For starting purposes the stop rings are moved to an excess fuel position which is achieved by a pin engaged in a slot in one of the rings. The pin is spring biased to move the one end and hence the other ring to an excess fuel position and is coupled to a fluid pressure operable piston which when the associated engine is started is moved by fluid pressure to move the pin to allow the spring to move the saddle member and stop into engagement with the stop.
