Zur Lösung dieser Aufgabe wird erfindungsgemaß ein Drehkolben-Verbrennungsmotor vorgeschlagen, dessen kreisförmig gestalteter Drehkolben zwei um 1800 versetzte Nocken aufweist, die mit den Drehkolben in einem zylindrischen Gehäuse umlaufen und an der Gehäusewand dichtend anliegen; weiterhin ist die Erfindung dadurch gekennzeichnet, daß das zylindrische Gehäuse drei radial in den von Kolben und Gehäuse gebildeten Ringraum einschiebbare und auf dem Drehkolben dichtend aufliegbare Schieber besitzt, die entsprechend dem Um- bzw. Durchlauf der Drehkolbennocken über eine an sich bekannte Nockenwelle ein- und ausgefahren werden. Die von den Drehkolbennocken und Gehäuse schiebern begrenzten Ringräume verändern beim Kolbenumlauf ihren Inhalt und bewirken auf diese eise das Ansaugen, Verdichten und Zünden sowie das Entspannen und Ausschieben der Verbrennungsgase, wobei gemäß der Erfindung jeweils nach einer halben Kolbenumdrehung das verdichtete Gasluftgemisch gezündet und arbeitleistend entspannt wird, so daß, im Gegensatz zu den bekannten Drehkolben-Verbrennungsmotoren mit nur einem Arbeitstakt je Umdrehung, der ;Jirkungsgr8d beim Anmeldungsgegenstand verdoppelt wird. fan kann den iirkungsgrad des Anmeldungsgegenstandes weiter dadurch verbessern, indem mehrere Drehkolben mit entsprechend versetzten Nocken mittengleich nebeneinander auf der 1-totorwelle innerhalb eines Gehäuses angeordnet werden. Ein weiteres merkmal der Erfindung besteht darin, daß auf der rotorwelle noch eine Gasturbine angeordnet ist, in welcher die heißen Auspuffgase nochmals Arbeit leistend entspannt werden und darüber hinaus unter erheblicher Verminderung des Auspuffgeräusches ins Freie gelangen. Schließlich ist als patentbegründender Fortschritt noch hervorzuheben, daß die kreisrunde Gestaltung von Drehkolben und Motorengehäuse wesentlich einfacher zu bearbeiten ist als die unrunden Teile bei den bekannten Drehkolben-Verbrennungsmotoren.According to the invention, a rotary piston internal combustion engine is used to achieve this object proposed, whose circular rotary piston offset two around 1800 Has cams which rotate with the rotary piston in a cylindrical housing and bear against the housing wall in a sealing manner; The invention is further characterized in that that the cylindrical housing three radially formed in the piston and housing Has an annular space which can be pushed in and rests on the rotary piston in a sealing manner, which corresponds to the rotation or passage of the rotary lobe cam over a known per se Camshaft can be retracted and extended. Those of the rotary lobes and housing Slider limited annular spaces change their content and cause the piston to rotate in this way suction, compression and ignition as well as relaxation and pushing out of the combustion gases, according to the invention each after one half Piston rotation ignites the compressed gas-air mixture and relaxes while performing work is, so that, in contrast to the known rotary piston internal combustion engines with only one work cycle per revolution, which doubles Jirkungsgr8d in the subject of the application will. fan can further improve the efficiency of the subject of the application by by placing several rotary pistons with appropriately offset cams next to each other in the middle be arranged on the 1-motor shaft within a housing. Another feature the invention consists in that a gas turbine is arranged on the rotor shaft is, in which the hot exhaust gases are relaxed again while doing work and, moreover, with a considerable reduction in exhaust noise into the open air reach. Finally, as a patent-establishing progress, it should be emphasized that that the circular design of the rotary piston and engine housing is much easier is to be machined than the out-of-round parts in the known rotary piston internal combustion engines.
