Patent ID: 7104765

Claim:
A hybrid compressor system for selectively transmitting a driving force of a vehicle-driving power source and a driving force of an auxiliary power source to a compressor of a vehicle air conditioning device, comprising: a clutch selectively transmitting the driving force of the vehicle-driving power source directly to the compressor from the vehicle-driving vower source and a one-way clutch selectively transmitting the driving force of the auxiliary power source to the compressor, the one-way clutch being mounted on the auxiliary power source, wherein the one-way clutch includes: an inner ring fixed to an output shaft of the auxiliary power source; an outer ring being concentrically and rotatably disposed on an outer side of the inner ring; and an interrupting means connecting the inner ring and the outer ring such that the driving force of the auxiliary power source is transmitted therebetween, and that the connection is released when a centrifugal force exceeds a predetermined value corresponding to the rotation of the outer ring, and wherein the outer ring is a pulley; and a belt for transmitting the driving force of the auxiliary power source to the compressor is wound around the pulley.
