A compressor is provided for guiding lubricating oil separated from the discharged refrigerant by an oil separator to a radial bearing supporting a drive shaft through an oil supply hole. A rotating member that rotates together with the drive shaft is provided adjacent to the radial bearing on the drive shaft, and lubricating oil is supplied to the radial bearing via a gap between an external surface of the rotating member and an internal surface of a circular hole that supports the rotating member. An oil support groove, which alternately communicates with the oil supply hole and the discharge hole every time the rotating member rotates once, is provided on the external surface of the rotating member, and the lubricating oil flowing in from the oil supply hole is intermittently discharged into a drive chamber via the groove and the discharge hole.

Compressor and method of lubricating the compressor

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.
