Adjustable segmented rotary twin port valve shaft

Claim 1

In an internal combustion engine, including an oil lubrication system, a cooling system, an improved heat resistant intake and exhaust rotary valve shaft system, for the primary purpose of the introduction, and exiting of gaseous mixtures to be consumed in an adjustable timing sequence within the combustion chamber, driven by the rotation of the crankshaft, wherein the improved heat resistant rotary valve system comprises a machined and lubricated bore having access to both the intake and exhaust manifolds and combustion chambers, an adjustable, segmented, serrated rotary valve shaft rotating within said bore which consists of smaller sections having serrated or notched ends containing both intake and exhaust passages, machined diametrically through the rotary shaft sections, intake and exhaust passages within said sections separated and sealed from each other by conventional annular seal rings, or carbon seals, the exhaust passage having a heat resistant tube or extention protruding into but not communicating fluidly with the interior of the intake passage within the individual segmented, serrated, rotary shaft section of the adjustable rotary shaft, for the function of further atomizing the incoming gaseous mixture, the intake passage converging to and diverging from the segmented shaft centers to form a venturi shaped passage, so as to accelerate the gaseous flow, said segmented sections having serrated or notched ends so as to enable the shaft sections to be adjustable so as to produce various specific valve timing requirements, and also to be easily replaceable or repaired, the adjustable rotary valve sections being held in position in the bore by spring loaded thrust bearings, the shaft being driven by the crankshaft at a ratio of four to one.
