ABSTRACT:
A fuel injection pumping apparatus for supplying fuel to an internal combustion engine in which there is provided a feed pump which supplies fuel from its outlet to an injection pump by way of a throttle valve. The outlet pressure of the feed pump is controlled by a relief valve which includes a valve element movable by the outlet pressure of the feed pump to spill fuel between the inlet and outlet of the feed pump. The valve element is subjected to a pressure which is generated by a device and which varies in accordance with the square of the speed at which the apparatus is driven. A pair of restrictors are disposed in a flow path between the outlet of the feed pump and the device and a branch conduit applies the pressure intermediate the restrictors to a fluid pressure operable device which controls the operation of the injection pump. One of the aforesaid pair of restrictors is adjustable in accordance with the setting of the throttle valve whereby the pressure of fuel supplied to the fluid pressure operable device will depend upon the amount of fuel supplied to the associated engine.
