초록 ▼

An improved rotary valve assembly for use in internal combustion engines involving a two-piece cylinder head accommodating rotary intake valves and rotary exhaust valves mounted on independent shafts, operating at one-quarter speed of the crankshaft rotation with each of the rotary intake valves and rotary exhaust valves having two passageways for the introduction and interruption of fuel/air mixture into the cylinder and the evacuation and interruption of evacuation of the spent gases from the cylinder, respectively, the lubrication of the rotary valve assembly being by a drip feed through a longitudinal conduit in each respective shaft and radial conduits in each respective shaft in registration with the bearing means supporting the shaft within the cylinder head.
