Patent ID: 8763358

Claim:
A rotary type internal combustion engine, comprising: a stator including at least one stator inlet opening intended to admit an operating fluid flow, and at least one stator exhaust opening intended to discharge burnt gases; and a rotor mounted in said stator in a fluid-tight manner and rotatable with respect to said stator around a rotation axis, said rotor having: at least one rotor inlet orifice oriented in an axial direction and intended to face said stator inlet opening in a manner such to receive said operating fluid flow when it is situated at said stator inlet opening, at least one combustion chamber communicating with said at least one rotor inlet orifice, and at least one rotor exhaust duct having a discharge orifice; wherein said at least one rotor exhaust duct leads in a transverse direction from said at least one combustion chamber to a periphery of said rotor to discharge burnt gases through said stator exhaust opening when said rotor exhaust duct is situated at said at least one stator exhaust opening, wherein said at least one rotor inlet orifice, said at least one combustion chamber and said at least one rotor exhaust duct are arranged for always being in fluid communication with each other during the rotation of said rotor without the interposition of valve means situated among them, and wherein said engine also includes seal means arranged for sealing said at least one rotor inlet orifice and the discharge orifice of said at least one rotor exhaust duct when said sealing means face the internal surface of said stator and for clearing said at least one rotor inlet orifice and the discharge orifice of said at least one rotor exhaust duct respectively when said at least one rotor inlet orifice faces said at least one stator inlet opening and, when the discharge orifice of said at least one rotor exhaust duct faces said at least one stator exhaust opening, said seal means surround said at least one rotor inlet orifice and the discharge orifice of said at least one rotor exhaust duct.
