ABSTRACT:
A rotary compressor has a vane slot for slidably supporting a planar vane, and a transverse slot for containing a spring cartridge. The spring cartridge can be a two piece molded structure having an internal support pin for a torsion spring designed to exert a biasing force on the slidable vane. The torsion spring has a relatively large number of coil convolutions, that minimize the unit torsional stress on the spring material.
