ABSTRACT:
A scroll compressor has a compression mechanism accommodated in a closed container and comprising a stationary scroll and an orbiting scroll. The stationary scroll includes a frame and a separate wrap element secured to the frame or otherwise movable relative to the frame. The orbiting scroll has a wrap element allowed to undergo circular translation with respect to the wrap element of the stationary scroll to compress gas. The wrap element of the stationary scroll is made of a readily machinable abrasion-resistant material to reduce the manufacturing cost of the scroll compressor.
