ABSTRACT:
An improved scroll compressor has an orbiting scroll wrap that is designed to always be at most equal in height to the fixed scroll wrap. The orbiting scroll wrap is preferably designed shorter than the fixed scroll wrap by a distance equal to the manufacturing tolerances on the height of the two scroll wraps added together. In this way, the present invention insures that in no acceptable parts will the height of the orbiting scroll wrap exceed the height of the fixed scroll wrap. In a situation where the height of the orbiting scroll wrap does exceed the height of the fixed scroll wrap, there is a tendency to limit the stable operational envelope of the system. By insuring that the orbiting scroll wrap height is always at most equal to the fixed scroll wrap height, the present invention avoids this limitation on the operational envelope.
