ABSTRACT:
A pair of rotary valves for an internal combustion engine positioned in a cylinder head over a cylinder block. The rotary valves include a pair of rotatable shafts, and a pair of sleeve supports having ports opening to the cylinder or cylinders of the engine. The pair of rotatable shafts can be either hollow or solid. The hollow intake shaft brings in a fuel mixture to an inlet passage that rotates into alignment with an intake opening in the intake shaft to the piston cylinder. The hollow exhaust shaft allows exhaust of burned gases from the piston chamber through an exhaust opening from the piston cylinder to an exhaust passage in the exhaust shaft and to the atmosphere. The solid rotatable shafts are provided with a diametrical intake channel and a diametrical exhaust channel that aligns with the openings to the piston cylinder and to the fuel mixture and to the atmosphere. Drive and timing gearing between the crankshaft and the intake and exhaust shafts are provided.
