Abstract

L'invention se rapporte à des systèmes à soupapes rotatives. Elle se rapporte de manière générale à un moteur thermique possédant un système à soupape rotative (1), une chambre de combustion (101) définie par un cylindre (102), et un piston (103) disposé à l'intérieur dudit cylindre, ledit système à soupape rotative comprenant un rotor (2A, 2B) de construction cylindrique, situé en position adjacente à la chambre de combustion de manière à permettre l'établissement d'une communication séquentielle et synchronisée entre la chambre de combustion et un collecteur (105, 106), ledit rotor étant caractérisé par au moins trois orifices d'échange coplanaires (11) répartis de manière égale sur la circonférence du rotor, et lesdits orifices d'échange étant interconnectés par l'intermédiaire de passages (12) à extension radiale, à l'intérieur du rotor.
