  • Power output corresponds to the same.

  • An additional advantage is that foaming is largely prevented, for example when pumping fuels or oil, which can occur, for example, when controlling a return flow channel.
  • At least the axially displaceable rotor is guided axially and radially in a correspondingly cylindrical control chamber of the machine housing.
  • the displaceable rotor is arranged coaxially with the cylindrical control chamber.
  • the actuating force can be controlled arbitrarily and works with hydraulic, gaseous and / or electrical means. It is essential that the pressures in the work areas counteract forces on the rear of the rotor in order to control the desired axial adjustment of the rotor and thus the leakage current between the work areas.
  • the space delimited by the rear of the rotor is closed in a pressure-tight manner in order to generate the actuating force by means of a liquid or gaseous medium.
  • the medium to be conveyed is used to generate the actuating force.

Abstract

L'invention concerne une machine à piston rotatif pourvue d'un rotor menant (4) et d'un rotor mené (3), dont les axes de rotation forment un angle axial défini et dont les dents s'engrènent les unes dans les autres, un des rotors pouvant être déplacé axialement dans le carter (1, 2) et sollicité par une force de réglage, opposée à la force induite par la pression de travail, et un intervalle de court-circuit est formé entre les dents des rotors par un déplacement approprié du rotor.
