ABSTRACT:
A liquid fuel pumping apparatus includes a centrifugal weight mechanism 14 which is coupled to a fuel control member through a lever. A spring is provided to oppose the action of the weight mechanism and this is coupled through a lever having an adjustable pivot point, to the lever through a closure member carried about an axially movable member coupled to the weight mechanism. A drilling in the member is supplied with liquid under pressure at a restricted rate. The pressure of liquid acts upon the closure member to urge the closure member relative to the member so as to uncover a groove communicating with the drilling. The pressure of liquid in the drilling is controlled so that it varies in accordance with the square of the speed and in the event that the pressure fails the closure member and the axially movable member will move relative to each other to cause a reduction in the fuel supplied by the apparatus.
