Abstract:
In a scroll compressor, a center of a turning scroll body is shifted with respect to a drive central axis so that a distance between a gravity center and the drive central axis in a turning scroll becomes smaller than a predetermined allowable value set based on theoretical displacement and mass of the turning scroll. A moment force about the drive central axis acting on the turning scroll is reduced during revolving, and an alternating force acting on an autorotation preventing pin in the turning scroll is reduced to an allowable level.
