ABSTRACT:
A high pressure pump for an engine fuel injection system, wherein the pump has a plurality of positive displacement pumping devices that are operating so that their delivery cycles overlap and so that the instantaneous speed of the pumping devices during their delivery strokes is constant so as to minimize pressure variations in the system and avoid the necessity of having the pump being driven in synchronized relationship to the engine output shaft. This permits the use of a variable speed drive so that the pump can be driven at speed ratios depending upon engine demand and/or eliminates the necessity for positive drives to maintain synchronization. A number of embodiments showing different pump configurations are disclosed.
