therethrough in accordance with the speed of the engine.
l n g c simple and efficient means for controlling the operation of the air inlet valve to pre-` vent irregularity in its' opening movement and to provide certain vnew and useful feabeing ,had to which, i
tion of the same'on the line :1f-y of Fig. l; and'Fig. 3 is a sectional detail on the line e-c of Fig. l.
' This invention is applicable to any form of .rarbureter having a chamber to which 4' f gasolene is supplied and' taken up by air drawn through the chamber by the suction stroke of an engine, but for convenience of illustration, a construction is 'shown in which a cast metal easing is formed with a bodyl portionl and a laterally extending portion 2 f-form-ing afloat chamber of any desired-construction a to which gasolene is supplied through a, pipe 3 land from which it is conducted into the lower end of the body 1. by `apipe4.
The body .of the carbureter for-nis -an' enlarged air chamber 5 Iand a reduced tubular extension 6 on the body,'forms a-r'niiihg chamber 7 above the air chamber. Theupper -endof the extension 6 is formed with a laterally extending flange -S by means of which the carbureter may beattached to'an engine manifold or other part to deliver explosive charges to an engine cylinder upon the suction stro-ke of its 4Ins-ton. Within the extension 6 at the upper -endof the mixing chamber is the usual throttle -or butterfly This invention relates to improvements inv The object of the inventiomis to provide tures in the construction and arrangement of parts; the invention consisting in the matters hereinafter set forth and more particularly pointed out in the claims, referenceI the accompanying drawing in AFigure 1 is a -vertical sectionyon the line -m of Fig. 2 through a carbureter embody-l ing the invention;- .Fig..2 is ahorizontal secy valve 9 for .controlling the How of the explosive chargesto the engine.
The body 1 is provided with a screw- 'tlira'ded opening in its lower end iiito which isscrewed a hollowcapv 10 formed wi h a `peripheral opening covered by a wire gauze or screenv 11 through which air is drawn into the carbureter. The lower disk orend12 of the cap is formed with an inwardly extending hub portionlthrough which the gasolene supply pipe elextends vertically upward into the'air chamber 5 with a spray nozzle 14 on its upper end adjacent the lower end of the mixing chamber 7. The inner or upper end of the cap 10 Vis formed with an axial air inlet opening 15, rand fitting within this opening is a vacuum valve 1G, having a lower head or disk 17 forming a closure for the opening 15 and provided with an axial opening through which the pipe al extends,
the valvebei'ng adapted'to slide freely upon the pipe. Thevvalve head is also formed with an upwardly .extending peripheral .guide wall 18 upon which is a tubular sleeve 19 havingan inwardly extending-flange 20 at its upper end to engage tlecupperV end of the wall18 of tlie'v`alve when the same is raisedf,` Asiinilar sleeve 21.1 is provided uponf the sleeve 19 and a like sleeve `22 upon the sleeve 21, each of 'the-latterfsleevesbeing also provided with an inwardly extending flange 20`at its upper end'to engage the upper end 'of the adjacent inner sleeve. These concentric sleeves are guided in their vertical movement by ribs 23 which extend radially inward from the wall of the air chamber, and each rib is formed with a shoulder 24 to engage the upper endof the outer sleeve 22l and limit the sleeves and valve in their upward movement. Luge 25 are provided on the upper endv of the cap 10 to extend upward into the chamber v5 at each side of the valve 16, and each of these lugs is formed with a notched inner edge forming stepped seats 26 for the lower ends of the sleeves to support said sleeves at difierent heights.
When in inoperative position, as shown in Fig. 1, the valve 16 rests upon the upper end 0f the hub 13 of the cap with its lower `end within-the air inlet opening 15 which is closed thereby, and the severaljsleeves are supported at graduated heights by the stepped lugs 25.
The air i"niet isl thus closed by the valve, butv upon the suction' stroke of the engine piston, ,said valve will be lifted by the partialvacuum formed in the air chamber and air will be'drawnin .through thescreen of the cap, upward through the opening 'l5 beneath the valve and lower edges of the sleeves into the air chamber. When thus lifted, theupper end of the wall 18v of said valve comes into contact with the flange A20 on the sleeve 19 which sleeve forms a movable weighted stop wili'always be stoppedat a certain height for the valve to its inertia beyond the point to which the suction alone would vliftit. When given free'nlimited movement, the operation of thieva'lve is therefore irregular, but by placifriprl the weighted stop in its path, the valve when actuated by-a given vacuum' and will not rise higher until the suction increases suliicientl-y to overcome the added weight of the sleeve 19 when said sleeve will be lifted by the valve: Further .increase in the speed of the engme and consequent increased, .vacuum will lift the valve and sleeve 19 until the upper end of said sleeve comes into contact with the flange on the sleeve 21.
`This`fsleeve 21 thus. becomes a Weighted movable stop to arrest the upward move- ,ment of the valve until the vacuum increases sufficiently to lift the valve and both. of the sleeves, and the sleeve 22 serves in a like manner, as a third movable stop. The valve is thus arrested -in its upward movement at three different points, preventingany perceptible variation in its operation due to inertia or inability to respond quickly tothe l lapidvariations 1n the vacuum. Ifa very light valve is'used in order to obviate the difficulty arising from inertia, it will open too freely and will not have sufficient Weight to cause it Ato fall quickly with the variations in the vacuum, but by providing the stop members Whi :h are lpicked up by the valve at diiierent points in its upward movement,
the valve is ,weighted in proportion`to' the efo -. tion',1 novable stops the ing movement of said valve, and a fuel sup'- I'plv member opening into said `chamber what I claim is:-
vacuum and caused to act quickly in its closing movement, at the same time permittmg the use of'a comparatively light valve which wili open quickly in starting.
