Abstract:
A rotary internal combustion engine, comprising a cylinder that is divided into an intake-compression chamber, an exhaust-power chamber, and a combustion chamber; a power output shaft transversely extending through said intake-compression chamber and said exhaust-power chamber, a first rotor and a first rotational valve plate being provided in said intake-compression chamber to fixedly mount around said power output shaft, a second rotor and a second rotational valve plate being provided in the exhaust-power chamber to fixedly mount around said power output shaft too, three first blades being separately pivotally connected at one end to vertexes of three angles of said first rotor such that they are equiangularly spaced along an outer periphery of said first rotor with another free end of each said first blades located after said pivotal end of a preceding first blade; three second blades being separately pivotally connected at one end to vertexes of three angles of said second rotor such that they are equiangularly spaced along an outer periphery of said second rotor with another free end of each said second blade located after the pivotal end of a preceding second blade; all said first and second blades having a smoothly curved outer surface, whereby when said first and second rotors rotate, the outer surfaces of these first and second blades successively come into tangent contact with inner surface of a cylinder wall in said intake-compression chamber and said exhaust-power chamber, respectively, under a centrifugal force, such tangent contact of said blade outer surfaces with said cylinder wall allowing said intake-compression chamber and said exhaust-power chamber to be respectively divided into three separated and sealed spaces; said combustion chamber being provided with an intake port to communicate with said intake-compression chamber and an exhaust port to communicate with said exhaust-power chamber; said first and said second rotational valve plates being formed of three first and second valve holes, respectively, said first and said second valve holes being so arranged that when said first and said second valve plates rotate about said power output shaft with one of said first and one of said second valve holes overlapping said intake port and said exhaust port, respectively, compressed air in said intake-compression chamber is admitted into said combustion chamber for combustion and burned and exploded gas in said combustion chamber is admitted into said exhaust-power chamber to rotate said power output shaft, respectively.
