ABSTRACT:
An internal combustion engine having a head with valve assemblies for controlling flow of intake and exhaust gases to and from piston chambers. A head plate is located between the head and a block having cylinders accommodating pistons. The head plate has openings in communication with the cylinders and valve assemblies. Each valve assembly has a continuous ceramic sleeve having an intake port, and an exhaust port. Rotatably disposed within the sleeve is a rotatable valve body having a valving combustion chamber open to a piston chamber. A spark plug is mounted on each valve body. A first pressure responsive seal mounted on the valving body has a sealing surface engageable with the sleeve. A second pressure responsive face seal is located between the head plate and the rotating valve body. The valving body and first seal are rotatably driven to sequentially align the valving combustion chamber with the intake port and exhaust port during the operation of the engine.
