ABSTRACT:
An internal axis single-rotation machine, wherein an external rotor and an internal rotor are mounted for intermeshing rotation about their own centers of gravity at different angular velocities within a casing and wherein two pairs of radially external sealing corner areas on the internal rotor kinematically describe internal lateral faces which define recesses in the external rotor and wherein internal sealing corner areas on the external rotor kinematically describe external peripheral faces on the internal rotor, the rotors being arranged in cooperating rotative relationship such that a meshing gear-like contact is maintained between the internal lateral faces of the external rotor and the lateral faces of the internal rotor.
