ABSTRACT:
A fuel injection pumping apparatus includes an injection pump and a delivery valve through which fuel flows from the injection pump to an outlet, the apparatus includes a spill passage and a valve for controlling flow through the passage. The position of the valve is determined by the speed of the associated engine and above a predetermined speed flow can occur through the passage so that no fuel flows past the delivery valve. The valve also enables when the engine speed is below a second predetermined value lower than the first predetermined value, flow to take place through the passage.
