Compressor and method of lubricating the compressor

Abstract

In a compressor that is configured to guide the lubricating oil separated from the discharged refrigerant by an oil separator to the radial bearing supporting the drive shaft, through an oil supply hole 29, a rotating member 30 that rotates together with said drive shaft is provided adjacent to the radial bearing on the drive shaft. Moreover, an outlet 29a of the oil supply hole 29 opens to the internal surface of a circular hole 31 that supports the rotating member 30. A channel 34 for restricting the flow rate comprises a gap defined between the rotating member 30 and the circular hole 31, and restricts the flow rate discharged front the oil supply hole 29 to the radial bearing, and at the same rime, the rotation of the rotating member 30 sweeps out foreign substances, such as sludge, from the outlet 29a of the oil supply hole 29.
