ABSTRACT:
A fuel pump includes a member movable angularly to determine three fuel settings when the pump is used to supply fuel to a supercharged internal combustion engine. The member is moved by a fluid pressure operable means which includes a piston connected to the further member by a pin and a sleeve in which the piston is mounted and which itself is slidable within a cylinder. Fluid under pressure can be admitted to the cylinder by way of a valve, the pressure of fluid depending upon the speed at which the apparatus is driven. A spring is provided to bias the piston and sleeve so that the further member assumes a first position. When fluid pressure is applied the sleeve and piston move the further member to a second position after which further movement of the sleeve is halted so that the pressure in the cylinder must rise appreciably before the piston alone can move the further member to its third position.
