Specification of Letters Batent.
Application led April 26 1910. Serial No. 557,765. l' v Patented Nov. 29, 19:10.
To all whom it may concern:
Be it known that I, BENJAMIN REBoUnG, civil engineer, citizen ofFrance, residingat Denain, Nord, in the Republic of France, havev invented new and useful Improvements in Carbureters, of which the following is a specification.
This invention relates to a carbureter of the general t e described in my pending application ggerial vNumber 474,210 iled J an. 26, 1909) and more particularly to the device by means of which the expansible annular part is actuated so as to vary the sectional area of the passage through the restricted portion of the same while operating at the same time the sliding tube con-l trollin the flow ofthe combustible liquid throng the sprayeil tube.
My invention consists in actuating said expansible annulanpart by rotating its mov-- able end which I preferably obtain by means of a rack meshing with teeth provided on the outer periphery of said movable end, the
rack being actuated either by means .of ay piston, a speed regulator or by hand.
By the particular arran ement of the strips forming the expansiblre part, the rotation of the movable end of said part has for its effect to move the same axially with regard to the fixed end of said part which results in varying the sectional area of the restricted portion of the same and also the.
number of the orifices in the sprayer tube left free by the outer sliding tube connected to said movable end. `|The above described manner of operating the expansible part has the advantage of necessitating only a small power for operating the expansible part so that the same responds exactly to the actuating means (piston, regulator or hand) wherebythe inflow of'explosive mixture is accurately regulated while the proportion of air and combustible .remains exactly the same. v
In the annexed drawing: Figure 1 is a vertical section through a carbureter ac-v cording to my invention, the rack being connected to a piston operated through the depression caused by the aspiration from the engine, the carburetor bein shown in its normal position ',inwhich t e flow of exy plosive mixture is minimum. Fig. 2 is a section smilar to Fig. 1, the iow of explosive mixture being maximum. Fig. 3 1s a section along the line 3--3, in Fig. 2. Figs.
4 and 5 show the expansible annular part on a larger scale, in elevation and cross section along the line 5 5, Fig. 4,l respectively.
-The combustible liquid contained in the constant level tank 1 1s led to the sprayer 2 consisting of a tube closed at its upper end below which it is provided with a number of small holes situated at various levels. A
constricted part of the sleeve being approximately on a level with the small holes of the sprayer.
` The lower end of the expansible annular I part or sleeve 5 is xed at its lower end to the body 6 of the carbureter and it is held at its upper end between a ring 7 and a nut 8 by which the upper part of the sleeve is guided in the carbureter lbody. The ring 7 i has radially extending arms and a central hub in which the tube 3 is supported. Said 'ring 7 is provided in its outer periphery with teeth 9 and a cylindrical rack 10 which is adapted to slide in the carbureter body meshes. with said teeth. The rack 10 is provided at its end with a piston or diaphragm 11 which is acted upon by a spring 12. The casing 17 of thecarbureter in which said diaphragm is located is divided thereby in two chambers 13, 14, the first of which communicates through an opening 15' ing to the speed which is regulated throu h thevalve 16 the depression caused by t e aspiration oi the cylinder and transmitted through the opening 15 on to the piston 11 e spring 12 as shown in dotted A said rack together with the 5 the sleeve in the direction of the arrow F' 15 ture 1s combustlble and air remains the sam'e as the- '125l When thev de 3 0 while the pro `remains exact ythe same.
permits the atmospheric- .rssure",ofcompressin #the s ring 12 Yan thereby vslidlngv 'l the Arac 10. lhering 7 is then rotated -b upper part of 8) the rotation being assistedby the exlbllity ofthe sleev that the sectional area of the A P throughtheconstricted-part of the sleeve is '10 increased --andfja .greater amount of. air is '-,suc'keddin' 'by the engine. At the same time,
the ring 'a' is lifted with the tube 3 which' opens a greater number of, holes in the sprayer, whereby the flow of explosive mixincreased while the proportion of respective amounts of the same increase with the same ratio and the velocity of air around the sprayer is substantially the same. When the yiovyv of explosive mixture is maximum the parts are in tlregposition shown in full lines in Figs. 2*"a'nd 3. If the depression decreases, the reverse movementstake place under lthe action of the springo1 2. gression caused by the engine increases or ecreases, the rack 10 is then moved in one direction or in the reverse di- `rection, respectively so that the How of the explosive mlxture is accurately regulated ortion of alr and combustible Ha g now described my invention, what I claim as new and desire to secure by Let ters Patent is:
1. A carbureter comprising in combination: a constant level tank, a sprayer having 'orifices situated at var'ous levels, a tube sliding over the sprayer and adapted -to cover It results .tlvlerefroml aspra theu per en o --desdrl` ed and for the purpose setr forth.
- 2. A carbureter comprising in combinapassage for the level ofthe orifices in the spra er, and hav' lmore or less the orifices in the latter, an expansible `annular part y passage for 'the air. approximately on the level of the orifice in th having a constricted e sprayer, and having its lower-end securedl to the carbureter body, and itsnp r end connected to the tube sliding over; er,'and means for rotating sald part, substantially as tion: a constant level tank, a s ra er having orifices -situated at various ivel's,` a tube `sliding over the spra er and adapted to cover more: or less the ori ces in the latter, an expansible annular part having Aa constricted air approximately on the lng its lower end secured to t e carbureter body, tube sliding over the'sprayer, teeth on said upper end, a rack engagin with said teeth,
