Abstract
There is disclosed a scroll-type machine suited for use as a gaseous fluid compressor. The machine incorporates symmetrical scroll members of substantially one wrap that have modified inner ends to provide continued sealing to a single separation point. The one wrap configuration and modified ends provide a very compact compressor design that enhances manufacturability and yet is able to deliver fluid gas with much greater pressure ratio versatility than conventional multi-wrap scroll compressors. The machine incorporates a discharge valve in the discharge port that allows various pressure ratios to be attained for a variety of end uses.
