The way it works....instead of the tube squirting gas down the venturi...the tube is redirected upward and the gas hits the underside of the concave "umbrella" disk. The underside of the disk can have channels going from the center of the disk to the outer edge of the disk.
I think the gas would atomize better if the edge of the disk were very thin or razor like.
One type of disk is formed from a mold using Buna-N rubber. Another type of disk is made out of stainless (which I think is a better idea...being able to sharpen the outer edge to razor-like...what the heck do I know lol)

My thoughts.....this really was used by a few people in the 70's....and after almost all cars were equipped with F.I. and ECMs by 1990....the powers that be decided to release the patent figuring no one would be interested in it.
Heck....I could be wrong...maybe.
I know gas vapor in the carb body is a bad thing (vapor lock)...but gas vapor in the manifold...can't see how that would be bad.
Except for a backfire......where the heck did that manifold and carb go?
I thought about posting this info under the "Carburetor" thread...but didn't want to get laughed off the forum.....yet.
