Abstract
A fuel injection pump assembly in which fuel delivered from individual cam lobe driven pump plungers is controlled by an engine driven drive shaft rotated control valve, the position of which, relative to the spill ports from the plungers, is controlled by means of a hydraulic governor. A separate governor cam lobe is used to also actuate the plungers whereby fluid supplied to the hydraulic governor is at a flow rate proportional to pump speed and therefore, engine speed.
