ABSTRACT:
A fuel pumping apparatus for supplying fuel to an engine has a high pressure pump which includes a component movable to determine the maximum amount of fuel which can be supplied to the engine. The component is biased by a spring to a minimum fuel position and to adjust the setting of the component there is provided a three armed lever one arm of which is coupled to the component. The other two arms are coupled to engine operating parameter responsive devices. In the example the device is a piston which is spring loaded and is responsive to the output pressure of a low pressure fuel pump and the device includes a diaphragm which is subjected to the air inlet manifold pressure.
