Abstract
A fuel pumping apparatus for supplying fuel to an engine includes a pumping plunger housed in a bore one end of which connects with an outlet and also by way of a valve with a source of fuel under pressure. Also provided is a further plunger housed in a further bore one end of which is connected to an accumulator volume. Cam means is provided to urge the further plunger towards the one end of its bore to compress the fluid in the accumulator and the outward movement of the further plunger under the action of the compressed fluid is transmitted to the pumping plunger to displace fuel through the outlet.
