Abstract A scroll-type hermetic compressor is disclosed including within a hermetically sealed housing a fixed scroll member assembly, an orbiting scroll member assembly, a frame member, and a crankshaft. The fixed and orbiting scroll member assemblies each include a separately formed involute wrap member interconnected with a plate member by means of a plurality of pin members received within corresponding axial bores in the wrap member and plate member, respectively. The plate member of the fixed scroll member assembly is mounted to the frame member, while the plate member of the orbiting scroll member assembly is mounted to a drive hub member operably coupled to the crankshaft. In one embodiment, the interconnecting pin members fit loosely within the bores in the wrap member such that the wrap member is movable with respect to the plate member, thereby providing radial compliance between the fixed and orbiting scroll member assemblies during compressor operation.
