Abstract A scroll-type hermetic compressor is disclosed including within a hermetically sealed housing a fixed scroll member assembly and an orbiting scroll member assembly. Each of the fixed and orbiting scroll member assemblies includes a separately formed involute wrap member, which is interconnected with a plate member by retention of an axial end portion of the wrap member within an involute channel in the plate member, as by a welded joint, a sintered joint, a press fit, or an interference fit. The involute channel extends between the face and back surfaces of the plate member, and the axial end portion of the wrap member is disposed within the channel such that an axial end surface of the wrap member is proximate the back surface of the plate member. 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.
