Abstract
A fuel pumping apparatus of the rotary distributor type has a fluid pressure operable valve which can be opened to terminate delivery of fuel to an associated engine. The operation of the valve is controlled by an axially movable shuttle contained in a cylinder. The shuttle is biased toward one end of the cylinder and is displaced away from the one end of the cylinder by fuel supplied by an auxiliary plunger. The shuttle is angularly movable by an actuating mechanism to vary the extent of movement before operation of the valve. The shuttle is biased to the one end of the cylinder by a shuttle return piston in order to reduce the frictional loads on the actuating mechanism. The cylinder containing the return piston is connected to an accumulator chamber.
