Abstract
A fuel injection pumping apparatus of the axially slidable rotary distributor type includes a cup shaped member mounted on a drive shaft and a distributor member which as a bore containing pumping plungers. The outward movement of the plungers is controlled by a tapered surface on the interior of the cup shaped member which co-acts with complementary surfaces on cam followers, disposed between the plungers and a surrounding cam ring. The slots in the cup shaped member which accommodate the followers are of helical or like form and the distributor member is driven angularly by tongues which are secured to the distributor member and which locate in the slots. As the distributor member moves axially it is also moved angularly by the action of the helical slots so that the timing of delivery of fuel remains constant.
