The fuel is conveyed from the restricted orifice in the jet member 28 through a cross bore 34 into a vertical bore 35 and from this bore the fuel flows through a cross bore 36 into thenozzle chamber and on up through the nozzle 27 through which it is discharged into the venturi 20. The fuel comes out of this nozzle with some velocity andis discharged into the most. rapidly moving portion of the air stream as it passes through the venturi 20.
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.
