ABSTRACT:
A hermetic scroll-type compressor 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 seal between the thrust surface and the back surface of the orbiting scroll member seals between a radially inner portion of the back surface exposed to discharge pressure and a radially outer portion exposed to suction pressure. The frame member defines an annular oil chamber having a side surface and a bottom surface above which the radially outer portion of the back surface orbits in spaced relationship. The oil chamber contains a sufficient depth of oil between the bottom surface and the back surface, whereby the oil exerts a reaction force on the back surface in response to rotating inclined wobbling motion of the orbiting scroll member.
