Abstract:
A compressor includes a closed container housing a compression element driven by the shaft of a motor. The compression element includes a first and second bearings supporting first and second shaft portions, and at least one cylinder having at least one cylinder chamber disposed between the first and second bearings. At least one roller is fitted to the shaft 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 opened to the at least one cylinder chamber and first and second elastic portions provided in first and second opposing surfaces, respectively. A diameter of the second shaft portion is smaller than a diameter of the first shaft portion. A rigidity of the second elastic portion is smaller than a rigidity of the first elastic portion.
