摘要

The machine has an operating chamber (5) provided between rotary pistons (3), where the chamber changes its volume and/or its length during rotation of the rotary pistons. The chamber is fillable with a compressible operating fluid over an inlet (18). Each rotary piston has an outer contour twisted along their axis of rotation in a screw-like manner. The pistons are twisted such that the chamber is closed by contraction of a piston intermediate area.
