Abstract

A fuel pump for a motor vehicle, wherein a unitary stepped body shell 9 has swell 12 dividing the shell into inlet and outlet chambers, the latter incorporating a diaphragm 21 which provides excess pressure compensation by allowing variations in volume in a closed chamber 22 defined between said diaphragm and the dividing wall. A pumping chamber 11 communicates with the inlet and outlet chambers through valves 15, 16.
