Rotary valving unit for an internal combustion engine

Claim 1

In combination with an internal combustion engine, said engine including an engine block, said engine having a plurality of separate spaced apart chambers located within said block, an inlet port and a separate exhaust port formed within said engine block for each said combustion chamber, a piston movably mounted within each said combustion chamber, gases being adapted to ignite and expand within each said combustion chamber causing said piston to be forcibly moved, the improvement comprising: a valving unit for supplying an ignitable gas mixture through said inlet port and for removing burned gases out through said exhaust port, said valving unit being mounted within a housing, said housing attached to said engine block, an inlet valve rotatably mounted within said housing, an exhaust valve rotatably mounted within said housing, both said inlet valve and said exhaust valve being cylindrical in configuration, said inlet valve having an interior inlet chamber being divided into a plurality of separate chambers with each said separate chamber connecting with a said combustion chamber inlet port through an inlet opening, each said separate chamber terminating just after its respective said inlet opening, said exhaust valve having a single interior exhaust chamber connecting with all said combustion chambers, said exhaust valve having a plurality of exhaust openings with each said exhaust opening connecting with a said exhaust port, both said inlet port and said exhaust port being non-circular in configuration and assuming an irregular shape resembling generally a rectangle to achieve even flow therethrough; drive means interconnecting said exhaust valve and said inlet valve to rotate such in the same direction at the same rotational velocity, said drive means operates in conjunction with the speed of said engine so that the gases are supplied through said inlet ports at the appropriate instance and the exhaust gases are discharged at the appropriate instance through said exhaust ports.
