  • Scroll compressor with improved rotation prevention mechanism
    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.
