Abstract
Abstract Means are disclosed for an improved carburetor wherein fuel is atomized for carburetion purposes by being pumped through a tube having a plurality of perforations in its periphery. The tube is covered by sleeves which telescope over it; and in reaction to either depression or release of the accelerator, the sleeves will move along the tube to either uncover or cover more or less of the holes, as desired. In this way, a more completely atomized fuel mixture is delivered to the carburetor under high pressure for improved efficiency. Tension means are also provided to return the sleeves to their normal or "idle" position following release of the accelerator.

Claim 1
Independent Claim
128 words
An improved carburetion device for use with an engine having a carburetor, a fuel pump for supplying fuel under high pressure and an accelerator, comprising; (A) a main fuel line (1) connecting to the fuel pump, (2) having a plurality of perforations in its periphery, and (3) passing through the air filled mixing chamber of the carburetor (a) whereby the fuel is forced through said perforations, atomized and mixed with the air; (B) a pair of cylindrical sleeves telescoped over said main fuel line and slidable therealong; (C) means attached to said sleeves for moving them toward and away from each other; and (D) said last mentioned means including springs secured to said sleeves and surrounding said main fuel line for normally urging said sleeves toward each other.

Claim 3
Dependent Claim
197 words
An improved carburetion device for use with an engine having a carburetor, a fuel pump for supplying fuel under high pressure and an accelerator, comprising: (A) a main fuel line (1) connected to the fuel pump, (2) having a plurality of perforations in its periphery, and (3) passing through the air filled mixing bowl of the carburetor (a) whereby the fuel is forced through said perforations, atomized and mixed with the air; (B) a pair of cylindrical sleeves (1) slidingly disposed over said main fuel line in opposed relationship, and (2) at least partially extending into the mixing bowl of the carburetor; (c) an operating linkage interconnecting the accelerator and said sleeves for translating accelerator movement into linear movement of said sleeves away from each other; (D) tension means (1) surrounding each of said sleeves and said main fuel line and secured thereto, and (2) normally urging said sleeves toward each other; (E) collapsible protective members surrounding said sleeves and said tension means; and (F) adjustable stop means (1) secured to the mixing bowl of the carburetor in opposed relationship, and (2) engagable with a part of said linkage as said sleeves are moved toward each other.
