  • Rotary compressor and refrigerating cycle device having bearings containing annular groove/elastic portion arrangement
    Patent number: 10690385
    Abstract: In one embodiment, an annular groove and an elastic portion are formed at an end portion of a main bearing on a side facing a cylinder chamber. An annular groove and an elastic portion is formed at an end portion of the sub-bearing on a side facing the cylinder chamber. A depth of the annular groove of the main bearing is formed larger than that of the sub-bearing. An outer peripheral surface of the elastic portion of the main bearing is formed in a straight shape so that thicknesses of a base portion and a tip portion of the elastic portion are the same. An outer peripheral surface of the elastic portion of the sub-bearing is formed in a tapered shape so that a thicknesses of a base portion of the elastic portion is larger than that of a tip portion of the elastic portion.

  • Horizontal rotary compressor
    Patent number: 7040880
    Abstract: A horizontal rotary compressor is configured such that an electrically powered compressor body is accommodated in a horizontally long hermetic receptacle in which a lubricating oil is accumulatively preserved, an interior of the hermetic receptacle is partitioned by a partition member into an oil storage portion space in which the compressor mechanism portion is positioned and an electric motor side space in which the electric motor portion is positioned, an oil communication portion is provided below the partition member, a gas communication opening is provided in an upper portion of the partition member, and an oil feed passageway is formed of a center opening, an oil guide opening, and oil suction tubing along the rotation axis.
