Abstract
A hermetic scroll-type compressor including a housing at discharge pressure, 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 back surface of the orbiting scroll member is exposed to discharge pressure to cause the orbiting scroll member to axially comply with the fixed scroll member. An internal pressure relief valve is connected within the housing to the suction space between the scrolls to compensate for moments of high discharge pressure and relieve orbiting scroll member over loading on the fixed scroll member.
