Abstract: A supercharger constructed in accordance to one example of the present disclosure can include a shaft portion connected to a pulley. A pair of supercharger rotors can be arranged for concurrent rotation with respective rotor shafts. A clutch rotor can be mounted to the shaft portion. The clutch rotor can rotate around a longitudinal axis. A clutch armature can be mounted to a drive shaft and unconnected to the shaft portion. The clutch armature can be configured to rotate around the longitudinal axis. The clutch rotor and the clutch armature can selectively cooperate in an engaged position and a disengaged position. In the engaged position, the clutch rotor and the clutch armature rotate together. An electric motor can have an output that provides a rotational input to one of the rotor shafts.

Abstract: A fluid pressure actuator assembly (44) adapted for use with a valve member (42) is disclosed, the actuator being of the type comprising a housing assembly (50), and an axially moveable diaphragm assembly (56). A linkage member (48) is operably associated with said diaphragm assembly and extends axially through a linkage opening (70), and is connected to a valve member (42). A preload member (74) includes a generally annular preload portion (76) between a stop surface (55) and the diaphragm assembly (56), and in engagement with both. The preload portion (76) maintains the diaphragm assembly (56) in a position corresponding to a first position of said valve member (42), in opposition to the force of a biasing means (68).
