INTERNAL COMBUSTION ROTOR ENGINE

A rotor engine, which comprises fourfold working pistons. The pistons forming jointly with a cylinder two ring-shaped compression chambers in the center section of the cylinder. The cylinder defines in one of its sections two combustion chambers. The pistons, being on a power stroke every time, the piston moves one side of the cylinder to the other side. The cylinder has a cylinder head including ports to pilot the intake to an exhaust from the engine by the pistons, compression pipes are also provided and passage means are arranged for a fuel-air mixture from the compression chamber through compression pipes to the top of valves in the cylinder heads. A rotor assembly comprises a left rotor and a right rotor. The rotors have cam-like tracks. At least one cylindrical runner assembly including at least one runner and are placed between the cam-like tracks of the rotors. The rotors include two cylindrical castings on a rotor shaft, such that they are facing each other, yet 90 DEG off set from each other, so that a high lobe of one of the rotors is opposite a low lobe of the other of the rotors, and being in constant contact with the cam-like tracks. A roller pin connects the runners and transmits the power stroke of the engine from the pistons to the runner, and the number of power strokes are available through the use of one cylinder and piston-assembly dependent upon the number of the lobes.
