Abstract
A positive fluid displacement scroll apparatus (compressor or expander) wherein the scroll members run with a small clearance between the wrap side flanks, thus essentially eliminating wearing of the wraps. When efficient radial sealing is attained, very little overall efficiency is sacrificed for the ability to construct low-cost scroll apparatus for a number of uses.
