Abstract
A scroll compressor housing has a center shell having an upper end defining an opening, and a top cap covering the opening and secured to the center shell. A crankcase is positioned within the housing. An orbiting scroll has a base plate and a spiral wrap extending axially from the orbiting scroll base plate. A fixed scroll has a base plate and a spiral wrap extending axially from the fixed scroll base plate nested with the spiral wrap of the orbiting scroll. A riser extends axially upwardly from the crankcase to provide a support surface for the fixed scroll. A radially extending flange on the crankcase is supported by an upper edge of the center shell and the fixed scroll is pinned between the top cap and the center shell. A fixed scroll seal sealingly engages the fixed scroll and the top cap to form a muffler chamber. A rabbet on the fixed scroll matingly engages a shoulder on the crankcase in order to fixedly align the fixed scroll and the crankcase.
