Abstract
There is disclosed a scroll-type machine particularly suited for use as a refrigerant compressor and incorporating an improved suspension system for the non-orbiting scroll whereby the latter may be pressure biased for the purpose of augmenting tip sealing. The machine also has a modified wrap tip and end plate profile in order to enhance performance, as well as an improved lubrication system for the drive and a baffle arrangement to provide a directed suction inlet. The machine also has an Oldham coupling utilizing a novel ring element which is non-circular and provides for increased thrust-bearing size, or reduced machine size. There is also disclosed a method of manufacture of a scroll-type machine.
