Method of making a scroll compressor pump cartridge subassembly

Abstract

The crankcase, fixed and orbiting scrolls and Oldham coupling are assembled to make a pump cartridge assembly as a subassembly of a scroll compressor. The pump cartridge assembly is tested to determine whether or not it operates satisfactorily. Upon successful testing, the pump cartridge assembly is installed in the shell of a hermetic compressor.
