  • Patent number: 6983729
    Abstract: A rotary piston machine having a housing defining a prismatic chamber the cross section of which forms an oval of odd order. A rotary piston is guided in the chamber and, in each position, subdivides the chamber into two working chambers. Piston-fixed instantaneous axes of rotation of the rotary piston are defined in a center plane. The rotary piston, in each interval of movement, is rotating with one of opposite nappe sections in an inner wall section about an associated instantaneous axis of rotation and is sliding with the opposite nappe section along the opposite second inner wall section of the chamber and is reaching a stop position there.
