CA 2182742

The machine comprises a cylindrical chamber (2) wherein are mounted two rotors (5 and 8) with an interpenetration configuration and forming with the chamber at least one capsuling wherein prevails a gas mixture according to the phases of a thermodynamic cycle. The rotor (5) is continuously rotationaly driven while the rotor (8) is intermittently rotationaly driven. The rotor (5) actuates a hydraulic pump hydraulicaly connected to a hydraulic motor coupled to the rotor (8). On the hydraulic circuit, between the pump and the hydraulic motor, is provided a valve for the opening of said circuit during the intake and explosion phases in order to prevent the rotation of the rotor (8) and for the closing of said circuit during the compression and exhaust phases in order to rotationaly drive the rotor (8). There is further provided an angular stop mechanism opposing the rotation of the rotor (8) during the explosion and intake.

La machine comprend une chambre cylindrique (2) dans laquelle sont montés en interpénétration deux rotors (5) et (8) formant avec la chambre au moins un capsulisme dans lequel évolue un mélange gazeux selon les phases d'un cycle thermodynamique. Le rotor (5) est animé d'un mouvement de rotation continu tandis que le rotor (8) est animé d'un mouvement de rotation intermittent. Le rotor (5) actionne une pompe hydraulique connectée hydrauliquement à un moteur hydraulique accouplé au rotor (8). Sur le circuit hydraulique entre la pompe et le moteur hydraulique est prévu un clapet assurant l'ouverture dudit circuit pendant les phases d'admission et de détente afin d'interdire la rotation du rotor (8) et sa fermeture pendant les phases de compression et d'échappement afin d'entraîner le rotor (8) en rotation. Est prévu de plus un mécanisme de butée angulaire s'opposant à la rotation du motor (8) pendant la détente et l'admission.
