ABSTRACT OF THE DISCLOSURE The present invention provides a liquid fuel injection pump suited for the sequential delivery of measured charges of liquid fuel under high pressure to an associated engine in timed relationship therewith comprising pump chamber means wherein the charges are pressurized to high pressure, a passage for delivering the fuel to said pump chamber means, a metering valve in said passage for regulating the amount of fuel in said measured charges of fuel, said metering valve comprising a pair of relatively movable members respectively having ports in the adjacent surfaces thereof adapted for registry, means to vary the amount of overlap of said ports in a first direction to control the quantity of fuel in each measured charge of fuel in accordance with the load on the associated engine, and means for controlling the relative movement of said members in a second direction transverse to said first direction to vary the amount of overlap of said ports in said second direction in accordance with the speed of the associated engine whereby the amount of overlap in said second direction increases with increased engine speed thereby to main- tain the quantity of fuel in sequential charges of fuel at a substantially constant level for a given setting of said means.
