A scroll compressor is disclosed. The scroll compressor includes a compressor housing; an orbiting scroll member disposed within the housing; a non-orbiting scroll member disposed within the housing, wherein the orbiting scroll member and the non-orbiting scroll member are intermeshed thereby forming a compression chamber within the housing; and an endplate secured to the non-orbiting scroll member. The endplate includes a check valve surface configured to provide a stop for a check valve of the scroll compressor, a radial sealing surface configured to receive a radial seal, an unloading mechanism surface configured to provide a stop for an unloading mechanism, and a pressure chamber for controlling the unloading mechanism, the endplate also including an aperture that fluidly connects the compression chamber and a discharge chamber of the scroll compressor.
