Abstract
A liquid fuel injection pumping apparatus for supplying fuel to an internal combustion engine includes, a high pressure injection pump, an electrically operated spill valve which when open during a delivery stroke of the injection pump allows fuel to flow to a drain. The apparatus includes a control valve operable to control fuel flow through passage means to the injection pump, the control valve having three positions in the first of which there is unrestricted flow of fuel, in the second of which there is restricted fuel flow and in the third of which fuel flow is prevented. An angularly movable shaft is provided to close the spill valve and the control valve is connected to a shaft. The shafts exterior of the apparatus are connected to mechanisms whereby when the control valve is moved from the first position to the second position the spill valve will be closed thereby to allow the apparatus to supply fuel at a restricted rate.
