ABSTRACT:
A scroll type fluid displacement apparatus, for example a refrigerant compressor, includes reinforcing ribs on the rear side of the base plate of the orbiting scroll element to provide rigidity to the base plate. Central and peripheral thrust bearings behind the base plate provide axial restraint for the orbiting scroll element, and one of the thrust bearings is arranged to maintain the fixed and orbital wrap in predetermined angular relationship. A swirling system for the fluid inlet into the scroll apparatus separates liquid from gas in the incoming fluid before it reaches the involute scroll wraps, and the tip edges of the scroll wraps are preformed so that the tip of each scroll wrap tends to expand under exposure to a differential thermal gradient between its inner and outer region to maintain a uniform tip clearance across its entire diameter under operating conditions.
