Abstract
Abstract A fuel separating device adapted to be connected between a carburetor and the intake manifold or integrally built into the intake manifold of an internal-combustion engine for removing excess fuel from the fuel-air mixture provided by the carburetor. The device comprises a housing having upper and lower chambers that are separated by a plate having a plurality of upright tubular members which communicate the upper chamber to the lower chamber. The device has an inlet port communicating the upper chamber to the outlet of the carburetor and an outlet port which communicates the lower chamber to the inlet of the manifold such that a fuel flow passage is provided for directing the fuel-air mixture from the carburetor to the manifold, while excess fuel droplets carried by the mixture are deposited at the bottom of the upper chamber. Means are provided for drawing off the excess fuel and returning it to the fuel supply tank.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
199 words
A fuel separating device adapted to be connected between a carburetor and an intake manifold of an internal-combusion engine for removing excess fuel from the fuel-air mixture provided by said carburetor, said device comprising: a housing having upper and lower chambers; plate means separating said chambers; an inlet port for communicating with said upper chamber and adapted to be connected to the outlet of said carburetor for communicating the fuel-air mixture from said carburetor to said upper chamber; an outlet port communicating with said lower chamber and adapted to be connected to the inlet of said manifold for communicating said fuel-air mixture from said lower chamber to said intake manifold; a plurality of upright tubular members extending through said plate means, one end of each of said tubular members terminating in the upper regions of said upper chamber, the other ends of said tubular members opening into said lower chamber to provide a fluid flow passage for directing said mixture from said carburetor to said manifold while excess fuel droplets carried by said air-fuel mixture drop to the bottom of said upper chamber; and means associated with said upper chamber for drawing off said excess fuel which accumulates therein.
Claim 2
Dependent Claim
199 words
A fuel separating device adapted to be connected between a carburetor and an intake manifold of an internal-combusion engine for removing excess fuel from the fuel-air mixture provided by said carburetor, said device comprising: a housing having upper and lower chambers; plate means separating said chambers; an inlet port for communicating with said upper chamber and adapted to be connected to the outlet of said carburetor for communicating the fuel-air mixture from said carburetor to said upper chamber; an outlet port communicating with said lower chamber and adapted to be connected to the inlet of said manifold for communicating said fuel-air mixture from said lower chamber to said intake manifold; a plurality of upright tubular members extending through said plate means, one end of each of said tubular members terminating in the upper regions of said upper chamber, the other ends of said tubular members opening into said lower chamber to provide a fluid flow passage for directing said mixture from said carburetor to said manifold while excess fuel droplets carried by said air-fuel mixture drop to the bottom of said upper chamber; and means associated with said upper chamber for drawing off said excess fuel which accumulates therein.
Claim 3
Dependent Claim
52 words
The fuel separating device defined in claim 1 further comprising an annular groove formed in the upper surface of said plate means within which said gas droplets accumulate; and a through bore extending through said plate for communicating with said annular groove for drawing said excess gas from said fuel separating device.
Claim 4
Dependent Claim
37 words
The fuel separating device defined in claim 1 wherein said means associated with said upper chamber draws off said excess gas which accumulates therein and communicates said excess gas to the fuel supply for said internal-combustion engine.
Claim 5
Dependent Claim
32 words
The fuel separating device defined in claim 2 wherein said conduit is connected to the fuel supply for said internal-combustion engine such that said excess gas is returned to said fuel supply.
Claim 6
Dependent Claim
37 words
The fuel separating device defined in claim 4 further comprising a pump disposed in said conduit for forcibly drawing said excess gas from within said fuel separating device and returning said excess fuel to said fuel supply.
Claim 7
Dependent Claim
42 words
The fuel separating device defined in claim 5 further comprising a one-way check valve disposed in said conduit between said fuel separating device and said pump to prevent the back flow of said fuel from said pump to said fuel separating device.
Claim 8
Dependent Claim
21 words
The fuel separating device defined in claim 1 wherein said inlet port is disposed in a side wall of said housing.
