Vaporization apparatus for internal combustion engines

Claim 1

Apparatus for the vaporization of a fuel mixture for internal combustion engines, said apparatus being placed below the throttle valve of a conventional carburetor and which comprises a body member provided with a central bore having a frusto-conical outlet section, a cylindrical array of circumferentially spaced bores having frusto-conical outlet sections, and which surround and are of the same length as and are co-axial with said central bore but have a smaller diameter thereby to provide different flow-through speeds, the outlet edges of said smaller diameter bores being tangent to the outlet edge of said central bore, a first supplementary air intake port positioned adjacent the inlet end of one of said smaller diameter bores and tangent to the edge thereof, means controlled automatically in accordance with the amount of depression generated by operation of the throttle valve from one position to another for varying the amount of air passed through said first supplementary air intake port, a second supplementary air intake port positioned adjacent the inlet end of another one of said smaller diameter bores tangent thereto and directly beneath the idling orifice of the carburetor, and means for manually controlling the amount of air passed through said second supplementary air intake port comprising a micrometric prick punch screw for variably closing off the air passage through the port.
