Describes it as a vertical rotary valve, without drawings, the page was just text, I understand it as a horizontal cylinder above a combustion chamber, that can be used on a 2 or 4 stroke engine, depending on what speed it rotates. The horizontal cylinder is hollow, it is divided, it is not just a hollow bore. The interior of the cylinder is also machined like a port tract on both the intake and exhaust tract. The advantage over most other systems, which are basically hollow cylinders is that a port is machined into the rotating cylinder which allows for a directed, elbowed, low angle port into and out of the cylinder, on both of the sides this would produce very good intake and exhaust port geometry and shape of the combustion chamber and much better flow. It would also allow reflected wave tuning of the intake and exhaust tracts. The rotary valve site said his design has a vertical valve body, text, no illustrations. Now imagination is literally defined as the ability to visualize objects within one's consciousness, in the 'mind's eye', I cannot visualize a cube or sphere, nothing at all (although I dream in sleep); since there are no pictures and I cannot visualize it, I interpret the text as meaning a horizontal rotary valve. The idea of internal bearings seems clever, as does the ceramic coating plus the use of multiple seals, on the shaft and at the port lips entering and exiting the combustion chamber, cooling jackets are provided to control the temperature of the rotary valve barrel, which is divided , intake from exhaust sides, with the intake charge entering one end, the exhaust exiting through the other.
I've either got to invent something or have kids ... so I can leave something good behind for future generations
EDIT - If I have misunderstood riff_raff's patent (very likely) and acidentally come up with something worthy of a new patent ... be sure to PM me. Something new under the sun, is seldom seen even though fully illuminated,
