摘要:
A scroll compressor with two scrolls including respective scroll wraps to form a compression chamber therebetween so that a volume of the compression chamber is decreased to compress a fluid therein by an orbital motion between the scrolls around an axis, has a frame supporting the scrolls thereon, a drawing force generator generating a drawing force urging axially one of the scrolls toward another one thereof, and a contacting force limiter bearing at least a part of the drawing force to prevent the at least a part of the drawing force from being born by a contact between the scrolls, when an axial distance between the scrolls is not more than a predetermined axial distance.
