Abstract
Abstract A distribution rectifier is described to render a uniform gasoline - air mixture for engines normally using a carburetor system and an associated manifold system connected thereto, the distribution rectifier comprising a foraminous cylindrical member having openings at its ends, a foraminous curved member attached along the peripheral edge to said cylindrical member, the curved member having a major orifice coextensive with the opening of said cylindrical member, and a minor orifice defined at the apex thereof, said minor orifice being situated axially within and substantially at the center portion of said cylindrical member.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
147 words
In a carburetor system for internal combustion engines which includes a carburetor for supplying a mixture of fluid fuel and air and an intake manifold, a distribution rectifier situated after said carburetor and in direct contact with the intake manifold, said distribution rectifier comprising a foraminous cylindrical member having an opening at the upstream end thereof, the bottom portion of said foraminous cylindrical member in direct contact with the intake manifold and closing the bottom portion of the downstream end thereof, a foraminous curved member attached along its peripheral edge to said cylindrical member at the upstream end thereof, said curved member having a major orifice coextensive with the opening of the upstream end of said cylindrical member, and a minor orifice defined at the apex of said curved member, said minor orifice being situated axially within and substantially at an intermediate portion of said cylindrical member.
Claim 2
Dependent Claim
147 words
In a carburetor system for internal combustion engines which includes a carburetor for supplying a mixture of fluid fuel and air and an intake manifold, a distribution rectifier situated after said carburetor and in direct contact with the intake manifold, said distribution rectifier comprising a foraminous cylindrical member having an opening at the upstream end thereof, the bottom portion of said foraminous cylindrical member in direct contact with the intake manifold and closing the bottom portion of the downstream end thereof, a foraminous curved member attached along its peripheral edge to said cylindrical member at the upstream end thereof, said curved member having a major orifice coextensive with the opening of the upstream end of said cylindrical member, and a minor orifice defined at the apex of said curved member, said minor orifice being situated axially within and substantially at an intermediate portion of said cylindrical member.
Claim 3
Dependent Claim
35 words
A distribution rectifier as recited in accordance with claim 1 wherein the ratio of areas defined by the major orifice to the area defined by said minor orifice is between about 15:1 to about 10:1.
Claim 4
Dependent Claim
16 words
A distribution rectifier as recited in accordance with claim 2 wherein the ratio is about 12:1.
Claim 5
Dependent Claim
20 words
A distribution rectifier as recited in accordance with claim 1 wherein said rectifier is provided with a plurality of perforations.
Claim 6
Dependent Claim
32 words
A distribution rectifier as recited in accordance with claim 4 wherein the area defined by a single perforation is about one-fourth the area defined by the minor orifice of said curved member.
Claim 7
Dependent Claim
18 words
A distribution rectifier as recited in accordance with claim 1 wherein said rectifier is made of stainless steel.
Claim 8
Dependent Claim
18 words
