Abstract
A scroll compressor that includes a housing and scroll compressor bodies disposed in the housing. A motor is disposed within the housing and operably connected to a drive shaft for driving one of the scroll compressor bodies. The drive shaft is rotationally supported at one end by a crankcase which includes a bearing housing and a bearing. The crankcase includes a plurality of openings or gas passages passing through the crankcase, as well as a plurality of generally cylindrical sections positioned respectively between adjacent openings. The cylindrical sections define contact regions which can engage an inner periphery of the housing when the crankcase is mounted therein.
