ABSTRACT:
An orbiting scroll member of a hermetic scroll-type compressor, including a scroll plate, a drive plate, and connecting pins coupling the two plates together in a manner permitting axial separation therebetween. A seal is unattachedly retained intermediate the scroll plate and the drive plate by a groove formed in the scroll plate. The seal extends out of the groove toward the drive plate to slidingly seal thereagainst. The seal defines fixed radially inner and outer portions of the scroll plate that are exposed to oil at discharge pressure and refrigerant at suction pressure, thereby imparting an axial compliance force. In one embodiment, the orbiting scroll plate is permitted to move transversely relative to the drive plate, by virtue of loose-fitting connecting pins, thereby facilitating radial compliance.
