PRE-TESTABLE AND REPAIRABLE HERMETIC SCROLL TYPE COMPRESSOR A hermetic type scroll compressor includes a hermetically sealed compressor housing formed by first and second cup shaped casings. The first casing houses a compression mechanism, while the second casing houses a drive mechanism. The compression mechanism includes a fixed scroll affixed to the first cup shaped casing, an orbiting scroll interfitted atan angular and radial offset with the fixed scroll, and a rotation preventing device disposed between the orbiting scroll and the center block. The movement of both the compression and driving mechanisms may be inspected or tested and those mechanisms may be readily disassembled so that component parts thereof may be adjusted or replaced before hermetically securing the first casing to the second casing. Furthermore, each casing is provided with a center block forming, in part, an alignment mechanism for aligning the drive mechanism drive shaft with the orbiting scroll of the compression mechanism. |
