Patent ID: 8641394

Claim:
A compressor configured to compress a refrigerant and using a lubricating oil, the compressor comprising: a compression mechanism configured to compress the refrigerant; a driving shaft configured to rotate about a vertical rotation axis in order to drive the compression mechanism; a slide bearing supporting the driving shaft to allow the driving shaft to slide therealong; a fixation member with the slide bearing fixed thereon; a circulation path formed in the compressor in order to circulate the lubricating oil therein, the circulation path being a path where the lubricating oil drawn up from a reservoir arranged at a housing of the compressor is returned to the reservoir; a first surface fixed to the driving shaft and intersecting with a line arranged in parallel to the rotation axis; a second surface facially abutted to the first surface; and a recovery space formed in the compressor, the recovery space being configured and arranged to recover the lubricating oil leaking out of bottom ends of sliding surfaces of the slide bearing and the driving shaft, the bottom ends of the slide bearing forming lowermost ends of the slide bearing the recovery space including a first space formed by surfaces when the driving shaft is supported by the slide bearing, the surfaces including a lateral surface of the driving shaft, the lateral surface continuing to the first surface, a bottom surface of the slide bearing, a surface continuing to the second surface, and a surface of the fixation member, the surface of the fixation member being positioned close to the driving shaft, and a second space connecting the first space and the circulation path, the second space being formed by an annular groove and a connection path, the annular groove being opposed to the slide bearing with a wall disposed therebetween, the annular groove extending upwardly from the bottom ends of the slide bearing to an uppermost free end of the slide bearing, the connection path penetrating the wall in order to connect the first space and the second space, and the first surface and the second surface respectively continuing to surfaces forming the recovery space.
