Abstract
A fuel injection pumping apparatus includes an injection pump for supplying fuel to an engine, feed pump for supplying fuel to the injection pump, and throttle means for controlling the amount of fuel supplied by the feed pump to the injection pump. Intermediate the throttle means and the feed pump is a first orifice, and downstream of this orifice is a tapping to which a control pressure is applied to a device operable to adjust the timing of injection of the injection pump. A valve is provided which includes a variable orifice connected in parallel with said first orifice, the valve being responsive to the outlet pressure of the feed pump to control the effective value of the first orifice.
