Abstract

L'invention concerne un nouveau moteur à piston rotatif constitué d'un carter de moteur (2) comprenant un espace intérieur (2.1) ainsi qu'au moins une entrée (2.2) et au moins une sortie (2.3), dans lequel un rotor cylindrique (3) pouvant tourner autour d'un axe de rotation (RA) dans un sens de rotation (DR) prédéterminé est reçu sur une surface de roulement (6) cylindrique qui s'étend concentriquement à l'axe de rotation (RA) et qui entoure avec sur une surface d'enveloppe (3.1) du rotor (3) et des nervures latérales (5.3) au moins un cylindre (5) de section transversale torique. Au moins un piston rotatif (4, 4') est disposé sur la surface d'enveloppe (3.1) du rotor (3). Au moins un contre-piston (7, 7') est reçu au moins en partie dans le carter de moteur (2). Ce contre-piston (7, 7') est monté de manière mobile dans le carter de moteur (2) ou le piston rotatif (4, 4') est monté de manière mobile sur le rotor (3) et au moins une entrée (2.3) avec soupape d'entrée (13) et au moins une sortie (2.3) sont associées à chaque contre-piston. Au moins la sortie (2.3) est disposée immédiatement avant le contre-piston (7, 7') dans le sens de rotation (DR) et au moins l'entrée (2.2) est disposée de manière adjacente à celui-ci dans le sens de rotation (DR). Au moins un contre-piston (7, 7') est entraîné par le rotor (3) par l'intermédiaire d'un système de commande mécanique de telle manière que le contre-piston (7, 7') suive à une distance minimale sans contact le contour du piston rotatif (4, 4') distant du rotor (3) lors de son cycle de travail.
