ABSTRACT:
A fuel injection pumping apparatus for supplying fuel to an engine is of the rotary distributor type and has an annular cam ring having cam lobes for imparting inward movement to a pumping plunger. The trailing flanks of the cam lobes define metering portions which are less steep than those of known pumps so as to extend the time during which the outward movement of the plunger is controlled by the cam lobes. In addition the apparatus includes a sleeve slidable in the distributor member of the apparatus and this incorporates a shaped recess which communicates with a source of fuel. The bore containing the plunger communicates with an inlet port which can be uncovered to the recess while the plunger is under the contact of the metering portion of the cam lobe. The sides of the recess are not parallel so that the amount of fuel which flows to the bore depends on the setting of the sleeve.
