Abstract
A fuel injection pumping apparatus of the rotary distributor type has a positively reciprocated pumping plunger slidable in a bore in the distributor member which is housed in a body part. The body part has a cylinder housing a piston resiliently biased towards an end wall. A recess in the end of the piston presented to the end wall can be connected to the bore by the plunger at a variable position during the delivery of fuel by the plunger and the cylinder has an enlarged end portion adjacent the end wall. The enlarged portion communicates with the bore during the pumping stroke of the plunger and rapid termination of fuel delivery is obtained when the recess is connected to the bore, due to movement of the piston away from the end wall.
