Abstract
A distributor type fuel pumping apparatus includes pumping plungers and auxiliary plungers both operated by cams as the distributor member is rotated. The pumping plungers are housed in a bore from which fuel is delivered to outlets in turn. In order to control the start and function of fuel delivery a shuttle is movable axially by the fluid delivered by the auxiliary plungers and is angularly adjustable. A sleeve is mounted about the shuttle and is movable axially in response to engine speed. The shuttle and sleeves define a spill path through which fuel can escape from the bore and which is closed after a first predetermined axial movement of the shuttle and they also define a flow path which is opened after a further predetermined axial movement of the shuttle. Fluid flow through the flow path operates a spill valve to allow spillage of fuel from the bore.
