Patent ID: 7418887

Claim:
A torque coupling assembly comprising: a rotatable torque coupling case disposed in a torque coupling housing and driven by an input shaft; at least one output shaft operatively connectable to said torque coupling case; a friction clutch for selectively engaging and disengaging said torque coupling case and said at least one output shaft; and an integral accumulator/pump housing located external to said torque coupling housing, said accumulator/pump housing homogeneously formed as a single-piece part for enclosing therein: a fluid pump for generating a pressurized fluid; and a fluid accumulator for selectively storing the pressurized fluid, said fluid accumulator including an accumulator reservoir being in fluid communication with an outlet port of said fluid pump; said accumulator/pump housing defining said accumulator reservoir therewithin; said fluid pump and said fluid accumulator supplying the pressurized fluid to said frictional clutch.
