摘要:
A compressor includes a closed container, a compression element disposed in the closed container, and a motor disposed in the closed container to drive the compression element via a shaft. The compression element includes a first and second bearings supporting the shaft. At least one cylinder having at least one cylinder chamber is disposed between the first and second bearings, with at least one roller fitted to the shaft disposed in the at least one cylinder chamber. The first bearing is disposed closer to the motor than the second bearing. The first and second bearings have first and second annular grooves formed in first and second opposing surfaces opposed to end faces of the at least one roller. The first and second annular grooves are opened to the at least one cylinder chamber. A width of the second annular groove is larger than a width of the first annular groove.
