A compressor includes a housing, a rotary shaft, a pulley, an electric motor, a pulley one-way clutch, and a motor one-way clutch. The shaft is rotatably supported by the housing. The pulley is operably connected to the shaft and includes a power transmission portion. When power is transmitted from a vehicular engine to the power transmission portion, the pulley is rotated. The electric motor rotates the shaft and includes a rotor, which is operably connected to the shaft. At least part of the electric motor overlaps the power transmission portion in the axial direction of the shaft. The pulley one-way clutch is located between the pulley and the shaft and selectively permits and prevents power transmission between the pulley and the shaft. The motor one-way clutch is located between the rotor and the shaft and selectively permits and prevents power transmission between the rotor and the shaft.

Hybrid power transmission system having first and second clutch mechanisms

A conventional hybrid compressor compresses gas when power is transmitted from a vehicular drive source via a power transmission mechanism and when an electric motor, which is incorporated in the power transmission mechanism, is actuated. A motor wiring component extends from the electric motor to the outside of the power transmission mechanism. The motor wiring is provided with shape maintaining means for maintaining the shape.

Wiring structure of motor in hybrid compressor

A housing of a compressor supports a rotary shaft. The rotary shaft is coupled to a pulley with a pulley one-way clutch and is coupled to a rotor of an electric motor with a motor one-way clutch. The pulley is supported by the housing with a pulley bearing. The electric motor overlaps a power transmission portion in the axial direction of the rotary shaft. At least two of the bearing, the pulley one-way clutch, the motor one-way clutch, and a brush device of the electric motor overlap each other in the axial direction of the rotary shaft. As a result, the size of the compressor is reduced in the axial direction of the rotary shaft.
