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 arrangment 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.

A scroll-type machine comprising: (a) a first scroll member having a spiral wrap thereon; (b) a second scroll member having a spiral wrap thereon; (c) support means for mounting said scroll members with said spiral wraps intermeshing with one another, said first scroll member being mounted for non-orbital movement with respect to said support means, and said second scroll member being mounted for orbital movement with respect to said support means and said first scroll member whereby said orbital movement will cause said wraps to define moving fluid pockets communicating between a low pressure and a high pressure; and (d) biasing means for biasing said first scroll member toward said second scroll member, said biasing means comprising means defining a first chamber containing fluid at a first pressure; and means defining a second chamber containing a fluid at a second pressure; said first and second pressures being greater than said low pressure; said first and second chambers being positioned such that said fluid at said first pressure and said fluid at said second pressure cooperate to exert a biasing force on said first scroll member in a direction toward said second scroll member and generally parallel to the axis of said orbital movement to thereby enhance sealing therebetween.
