ABSTRACT:
A fuel pumping apparatus for supplying fuel to an internal combustion engine includes an axially movable member urged in one direction against the action of a governor spring by means of a centrifugal weight. A reaction member for the pivot of the weight bears against one member of a dashpot which includes resilient means in the form of a spring acting in opposition to the force exerted by the governor spring. A valve controlled passage including a ball element allows substantially unrestricted flow of liquid into the dashpot chamber when the latter is increased in volume by the action of the spring but a restricted leakage path is provided to control the reduction in volume of the dashpot chamber as the force exerted by the governor spring and the weights increases. The axial setting of the member controls the quantity of fuel which is supplied to an internal combustion engine.
