  • Patent number: 8690556
    Abstract: There is disclosed a rotary compressor which delays a pressure rise on a high pressure chamber side in a cylinder of a rotary compression element to decrease a high pressure load applied to a roller and a rotary shaft, thereby improving performance. In the rotary compressor including a sealed container in which an electromotive element (a driving element) and first and second rotary compression elements driven by a rotary shaft of the electromotive element are included, each of the rotary compression elements being constituted of a cylinder, a roller fitted into an eccentric portion formed on the rotary shaft to eccentrically rotate in the cylinder, and a vane which abuts on the roller to partition the inside of the cylinder into a low pressure chamber side and a high pressure chamber side, the inner diameter of a suction passage formed in each cylinder is 59% or more and 70% or less of the thickness of the cylinder.

  • Patent number: 7850436
    Abstract: A structure and method for fixing an upper cup muffler to an upper bearing portion. The upper bearing portion includes a step portion having an upper, lower and side surfaces. A peripheral edge portion between the upper and side surfaces of the upper bearing portion is declined outwardly to have a slant surface. The upper cup muffler includes a bottom surface and a peripheral side surface lower portion that extends downwardly from the edge portion of the bottom surface. The peripheral side surface lower portion gets across the slant surface of the upper bearing portion and is brought into linear or planar contact with at least one of the outer side surface and the lower surface of the step portion when the bottom surface of the upper cup muffler and the upper surface of the upper bearing portion are fixed to each other.
