Abstract: A supercharger includes a rotor housing defining a pair of cylindrical chambers. A driving shaft bearing is to support a driving rotor shaft for rotation in the rotor housing. A driven shaft bearing is to support a driven rotor shaft for rotation in the rotor housing. An oil sump housing is to enclose a timing gear end of the rotor housing. A shaft seal is disposed between the rotor housing and each respective rotor shaft. The oil sump housing, the rotor housing and driving and driven shaft seals define a closed container for oil to lubricate the driving shaft bearing, the driven shaft bearing, a driving timing gear and a driven timing gear. The oil pools in the closed container and a top surface of the oil is spaced below the timing gears when the driving rotor shaft is in a vertical orientation.

Abstract: A boost system for providing boost pressure to an air intake manifold of an engine includes a supercharger having rotors and a supercharger input shaft, an electric motor/generator, and a planetary gear set. The planetary gear set operates to transfer torque between the supercharger input shaft, the electric motor/generator and a crankshaft of the engine. The boost system can have a compact configuration.
