Abstract

A liquid fuel pumping apparatus including a shuttle the excursion of which determines the maximum quantity of fuel which can be supplied to an engine, the extent of outward movement of the shuttle being omitted by a stop in the form of a piece having a contoured surface, the stop being mounted in a fluid pressure operable piston. The position of the piston depends upon the speed at which the apparatus is driven. In addition the setting of the piece is determined by axially movable member the axial position of which is determined by a diaphragm to which is applied air under pressure from the inlet manifold of the associated engine.
