  • Patent number: 8714950
    Abstract: A scroll compressor is provided that can reliably prevent a situation in which a product whose performance is degraded due to misassembly of a tip seal is shipped. In the scroll compressor, tip seals of different lengths are embedded in tip surfaces of a fixed spiral wrap of a fixed scroll and an orbiting spiral wrap of an orbiting scroll. Among the tip seals, thicknesses of the shorter tip seals are made thicker than thicknesses of the longer tip seals, and depths of seal grooves in which the tip seals are embedded, respectively, are formed to different depths in correspondence with the thicknesses of the respective tip seals.

  • Patent number: 8308461
    Abstract: To provide a scroll compressor capable of reducing a noise occurring in a pin-and-ring type self rotation preventing mechanism and improving compression performance. In a scroll compressor comprising: a fixed scroll member and a revolving scroll member; a driven crank mechanism for driving the revolving scroll member to revolutionary turn; and a pin-and-ring type self rotation preventing mechanism provided in plural places for preventing self rotation of a revolving scroll member, at least one of the self rotation preventing pin, the self rotation preventing ring and the self rotation preventing ring hole, which form the pin-and-ring type self rotation preventing mechanism, is provided with an orbit correction part for reducing a maximum displacement R in a direction of self rotation of the revolving scroll member to smooth a change of an orbit of the revolving scroll member in changing a pin and a ring in a section of prevention of self rotation by means of a corresponding pin and ring part.
