ABSTRACT:
A scroll compressor includes scroll compressor bodies with axial tip seals projecting from the respective scroll ribs of fixed and movable scroll compressor bodies. An extended thrust region is provided in surrounding relation to an inner axial tip sealing region to provide for carrying thrust loads in the event that the scroll compressor bodies are forced axially together. Part of the thrust region may carry a tip seal, while another part may be free of a tip seal. This provides for at least a nominal reverse operation capability.
