Abstract
A dual input fluid pump system for coupling to a transmission or an engine and an electrical motor is disclosed. The system may include a first external gear, vane, internal gear, or gerotor-type pump, a second external gear pump, and connecting shaft. Gears of the second pump include one-way clutch bearings that enable operation of the system in multiple modes including engine-only; motor-only; a combined mode where the engine operates the first pump via the shaft and the motor operates the second pump with an external gear rotating in its pumping direction at a rate greater than the shaft; inlet boost; and a disconnection mode. Also noted is a pump that has a first shaft for coupling the engine to a first external gear and a second shaft for coupling the motor to a second external gear, as well as a one-way clutch bearing that performs in a similar manner.
