Rotary type internal combustion engine

摘要

The engine includes a stator including an inlet to admit a compressed gaseous oxidant flow, and an exhaust to discharge burnt gases; and a rotor mounted in the stator in a fluid-tight manner and rotatable with respect to the stator around a rotation axis. The rotor has an inlet orifice oriented in the axial direction and faces the inlet opening in a manner to receive the compressed air flow, a combustion chamber communicating with the inlet orifice, and an exhaust duct which leads in a transverse direction from the combustion chamber to the periphery of the rotor for discharging burnt gases through the exhaust. The inlet, the combustion chamber and the exhaust duct are arranged in fluid communication with each other during the rotor rotation, without the interposition of valve members. Seal members seal the inlet orifice and the exhaust duct when they face the internal surface of the stator.

1. 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, andat 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, andwherein 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.
