Rotor engine

A rotor engine having air-compressing components and engine components comprising an air-compressing rotor and an engine rotor which are fitted on a principal shaft generally parallel to one another to thereby provide an axially outer face and an axially inner face of each said rotor;

• a gas shield disk mounted between said air-compressing rotor and said engine rotor to thereby separate said air-compressing rotor from said engine rotor;
• end plates mounted at said axially outer faces of both said air-compressing and engine rotors;
• wherein said air-compressing rotor, said engine rotor, said gas shield disk and said end plates being tightly retained in a chassis, said chassis having an air inlet and compressed air outlet provided therein at positions radial to said air-compressing rotor and a compressed air inlet and an exhaust port provided in said chassis in a region radial to said engine rotor;
• said compressed air outlet of said air compressing rotor being fitted with an exhaust valve to regulate compressed gas out of said compressed air outlet and said compressed air outlet and said compressed air inlet communicating with each other to permit compressed air to flow therebetween into a combustion chamber formed adjacent to said compressed air inlet;
• means for igniting said compressed air in said combustion chamber;
• said air compressing rotor having at least one air intake groove formed along the outer periphery thereof to define a first volume varying chamber formed between said air-compressing rotor and said chassis;
• said engine rotor further having at least one expansion groove formed along the outer periphery thereof to define a second volume varying chamber formed between said engine rotor and said chassis and an auxiliary exhaust groove cut therein adjacent the trailing edge of the expansion groove to assist in exhausting exhaust gas from the combustion chamber and through said exhaust port;
• and spring-biased abutments reciprocally movable in said chassis, each having a respective end thereof in abutting engagement with said outer periphery of said air-compressing rotor and said engine rotor to thereby vary the amount of air contained within said air inlet and exiting said compressed air outlet due to said first volume varying chamber and to vary the amount of compressed air in said combustion chamber and exiting said exhaust port due to said second volume varying chamber.
