Abstract
A fluid pump system for an engine includes a transmission acting as a first pump and a second pump. In one embodiment, the first pump is a scavenge pump and the second pump is a pressure pump with the transmission being a gear set for altering a drive ratio between a transmission input drive and an input drive of the second pump, thereby allowing additional control of a speed of the second pump in comparison to the engine. The transmission, acting as a scavenge pump, can provide a scavenge pump function to an oil pan of the engine, returning engine oil that is present there from both normal drain back and acceleration/deceleration forces.
