SCROLL COMPRESSOR

摘要

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 (25) and a revolving scroll member (27); a driven crank mechanism (55) for driving the revolving scroll member (27) to revolutionary turn; and a pin-and-ring type self rotation preventing mechanism (33) provided in plural places for preventing self rotation of a revolving scroll member (27), at least one of the self rotation preventing pin (63), the self rotation preventing ring (65) and the self rotation preventing ring hole (27D), which form the pin-and-ring type self rotation preventing mechanism (33), being provided with an orbit correction part (67) 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.
