The walls of this venturi serve as baflies to straighten out the flow; of the fuel. thereby preventing it from striking the walls of the air chamber or the conduit 8 until after it has been vaporized by additional air entering the venturis '19 and 7. I consider this an important feature of the invention, for tests have shown that when liquid fuel is per mitted to strike the outer wall of the mixing conduit, it is likely to be carried along in liquid form by the air stream in such a way that vaporization and distribution are not efficiently accomplished.
By the above arrangement, I am enabled to avoid the necessity for mixing air with the fuel in the fuel passageways and nozzles (That's Emulsion or Air Bleeding he's talking about my emphasis) which would cause the delivery of the fuel in slugs and generally inefficient operation of the carburetor, particularly at low speeds.
