摘要：
A scroll type refrigerant compressor having an aluminum or aluminum alloy housing unit in which a stationary scroll unit having a stationary spiral member and a movable scroll unit having a movable spiral member are encased in such a manner that the movable spiral member moves along a predetermined orbiting path without rotating about an axis thereof, and a reinforcing ferric metal liner fixedly attached to an inner cylindrical face of a cylindrical wall portion of the aluminum or aluminum alloy housing unit so as to prevent the inner cylindrical face of the housing unit from being mechanically cracked by the movable spiral member of the movable scroll unit during the running of the compressor even if the movable scroll unit jams due to entrance of foreign materials between the outer face of the movable spiral member and the inner face of the housing unit.
