ABSTRACT:
A hermetic scroll-type compressor is disclosed including a housing, fixed and orbiting scroll members, a frame member having a thrust surface adjacent the orbiting scroll member back surface, and a crankshaft coupled to the orbiting scroll member. A non-sealing stabilizer ring device is disposed between the frame member and the orbiting scroll member to eliminate the small perturbation wobble remaining after the orbiting scroll member reacts with the oil pool thereby reducing scroll wear-in time. A stabilizer ring is mechanically or positively spring loaded by a wave spring washer to axially force the orbiting scroll member toward the fixed scroll.
