Patent ID: 7500463

Claim:
A four-cycle, rotary internal combustion engine with rotating combustion chambers, comprising: two side cover lids; a hollow stator with inner cylindrical surface; and a rotor having a right-prism body of the same height as of said stator and a rhombus-shape base with round angles and convex sides whose big diagonal equals the diameter of the hollow core of said stator; wherein said rotor further comprising: two combustion chambers located on opposite ends of the big diagonal of rhombus-shape base of said rotor; a spark plug being disposed in each of said combustion chambers; a source of high voltage being timely connected to said spark plug during rotation of said rotor to ignite air-fuel mixture within each of said combustion chambers; two radial rectangular grooves being flanking said combustion chambers along a whole height of the rotor; slot openings the height of said rotor, wherein each of said combustion chambers connects to the uppermost part of said radial rectangular grooves via said slot openings; sliding covers having a rectangular body with the same height as of said rotor and being positioned in said radial rectangular grooves flanking said combustion chambers of said rotor; wherein said sliding covers are provided with a means of moving in a radial direction within said radial rectangular grooves of said rotor opening and closing said slot openings of said combustion chambers; and wherein said rotor is positioned in said stator concentrically to said inner cylindrical surface forming the hollow core thereof, and said two side cover lids of said stator.
