Leakage Loss Flow Control

Abstract

A rotating piston machine includes a driving rotor and a driven rotor, the axes of rotation of the rotors enclosing a particular axial angle. The rotors include gear teeth which mesh with one another. One of the rotors is adjustable axially in the housing and is acted upon by an adjusting force which counteracts the force brought about by the working pressure and a short circuiting gap between the gear teeth of the rotors by virtue of the appropriate displacement of the rotor.
