Rotary valve internal combustion engine
A rotary valve internal combustion engine is described which comprises: a cylinder block having a cylindrical recess therein, a cylindrical bore transverse to the cylindrical recess, an exhaust passageway leading from the cylindrical bore, and an intake passageway leading to the cylindrical bore. A cylindrical piston sealably reciprocable in the cylindrical recess wherein the space defined by the piston and the walls of the cylindrical recess forms a combustion chamber. An arcuate passageway in the block between the cylindrical bore and the combustion chamber; a crankshaft connected to the piston; ignition means in communication with the combustion chamber; carburetion means in connection with the intake passageway to provide a fuel-air mixture; a cylindrical valve rotatably received in the cylindrical bore, the cylindrical valve having a hollow cylindrical body, open ends, at least two axially aligned intake ports near one end of the cylindrical body, at least two axially aligned exhaust ports near the opposite end of the cylindrical body, at least four axially aligned arcuate center openings between the exhaust ports and the intake ports, and at least for internal tubes, each tube connecting one of the center openings with one of the intake or exhaust ports; a sprocket wheel extending from one end of the cylindrical valve; and a tooth belt extending between the sprocket wheel and the crankshaft.
