Abstract
A scroll compressor having a housing, a fixed scroll and an orbiting scroll nested with each other to provide a pressure continuum of suction, intermediate and high pressure regions between said scrolls during compressor operation, the base of the orbiting scroll being axially slidably mounted on a thrust plate for allowing only axial motion of the orbiting scroll with respect thereto, a coupling device on the housing or fixed scroll and associated with cooperating coupling elements on one or both of the thrust plate or the orbiting scroll for preventing angular motion of the orbiting scroll with respect to the housing or fixed scroll, an axial compliance seal between and contacting the base of the orbiting scroll and the thrust member and defining an axial compliance pressure chamber, and one or more conduits connecting the chamber with one or more pressure regions.
