Abstract
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.
