ABSTRACT:
A rotary valve for an internal combustion engine comprises an outer stationary support member formed with a hollow interior, an inner valve member housed within the hollow interior, and bearing means supporting the valve member for rotation about an axis at one-half or one-quarter engine speed, depending on the embodiment. The outer support member and the inner rotatable member are formed with port and duct means of various configurations for selectively enabling and preventing the flow of intake and exhaust gases through the valve in accordance with the angular position of the inner rotatable member with respect to the outer support member. Annular and strip seals are mounted between opposing surfaces of the outer support member and the inner rotatable member to prevent leakage of gas therebetween. A portion of the duct means formed in the outer support member serves also as a portion of the combustion chamber. Impeller means is mounted within the portion of the duct means formed within the inner rotatable member for producing a mixing and supercharging effect upon rotation of the inner rotatable member. The relative arrangement of the valve bearings and of collector and distribution pieces facilitates cooling and lubrication.
