Abstract
Abstract A fuel proportioner having a body in which a cylindrical control element rotates, the control element having a passage therein into which fuel is introduced; the body has a pair of oppositely disposed fuel passages for introducing fuel into the passage of the control element and for removing excess fuel. A second pair of oppositely disposed passages are provided in the body, angularly positioned relative to the fuel passages, for introducing gas into the control element passage and for receiving the fuel and gas discharged therefrom. The control element is axially slidable to vary the quantity of fuel, and in alternate embodiments, the control element has either single or plural diametrically extending fuel passages. In a third embodiment, the passages of each pair are angularly spaced less than 180* , and each pair of body passages are oppositely disposed, the passage in the control element being plural, axially spaced segmentlike passages.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
136 words
A fuel proportioner comprising: a. a hollow body having a cylindrical bore therein, b. liquid fuel inlet passage means extending from the exterior of said body to said bore, c. liquid fuel outlet passage means circumferentially spaced from said fuel inlet passage means extending from said bore to the exterior of said body, d. gas inlet passage means extending from the exterior of said body to said bore, e. outlet passage means circumferentially spaced from said gas inlet passage means extending from said bore to the exterior of said body, and f. a continuously rotating cylindrical control element journaled in said bore, said control element comprising passage means therein for sequentially connecting first said fuel inlet passage means with said fuel outlet passage means and then said gas inlet passage means with said outlet passage means.
Claim 2
Dependent Claim
136 words
A fuel proportioner comprising: a. a hollow body having a cylindrical bore therein, b. liquid fuel inlet passage means extending from the exterior of said body to said bore, c. liquid fuel outlet passage means circumferentially spaced from said fuel inlet passage means extending from said bore to the exterior of said body, d. gas inlet passage means extending from the exterior of said body to said bore, e. outlet passage means circumferentially spaced from said gas inlet passage means extending from said bore to the exterior of said body, and f. a continuously rotating cylindrical control element journaled in said bore, said control element comprising passage means therein for sequentially connecting first said fuel inlet passage means with said fuel outlet passage means and then said gas inlet passage means with said outlet passage means.
Claim 3
Dependent Claim
37 words
The fuel proportioner of claim 1, wherein said fuel passage means are in diametrically opposed relationship and said second-mentioned passage means are in diametrically opposed relationship and said passage means in said control element extending diametrically therethrough.
Claim 4
Dependent Claim
27 words
The fuel proportioner of claim 2, said control element passage means consisting of plural parallel and axially space passages, and means for axially sliding said control element.
Claim 5
Dependent Claim
24 words
The fuel proportioner of claim 1, said fuel passage means being angularly spaced less than 180* , said control element passage means being segmentlike.
Claim 6
Dependent Claim
26 words
The fuel proportioner of claim 4, said control element passage means consisting of plural segmentlike passages axially spaced, and means for axially sliding said control element.
Claim 7
Dependent Claim
50 words
The fuel proportioner of claim 1, wherein said control element comprises two parts having spaced opposed surfaces defining said passage means therein, one said part being axially movable relative to the other part to thereby change the volume of said passage means, and means for sliding said one part axially.
Claim 8
Dependent Claim
26 words
The fuel proportioner of claim 1, wherein said passage means in said body have greater axial extent at said bore than on the exterior surface thereof.
