ABSTRACT:
A fuel pumping apparatus of the rotary distributor type includes an accumulator volume into which fuel can be spilled to terminate delivery of fuel by the apparatus. The accumulator is defined by a movable member in the form of a sleeve which is slidable on an extension of the distributor member and has a closed end. The extension defines a seating with which can be engaged by a valve element defined by the sleeve. The extension and sleeve define an annular space connected to the pumping chamber of the apparatus and mechanical means is provided to effect initial movement of the sleeve against the action of a spring to lift the valve element from the seating to allow fuel flow into the accumulator volume.
