ABSTRACT:
An accumulator/pump housing associated with a motor vehicle hydraulic system that is designed to incorporate a gerotor pump and an accumulator. The accumulator/pump housing comprises a portion of a torque coupling assembly in which a friction clutch selectively engages and disengages a torque coupling case and at least one output shaft. The accumulator/pump housing is located external to a torque coupling housing and at least partially encloses a gerotor pump and a fluid accumulator. The gerotor pump pressurizes the hydraulic fluid and the fluid accumulator selectively stores the pressurized fluid. The hydraulic pump and accumulator supply pressurized fluid to actuate the friction clutch.
