In the following ilfiSCiiQ'ilOfi and in the claims, par 5 will he iilenliiiecl by specific names for convenience of expression but they m are intended to be generic in "their up plicuti'oh'to similar aris 21Sih6 211i1 will permit; In the accompanying (lruwings, there is shown organization of parts which is 95 somewhat conventimulund include an uppm 02' float Chamber l0, hung from u flange ll of a supporting top 12, From another fiungelB is hung-a lower or feed chamber 14 enclosing the float- \"hzimber and pro-tidal 100 with an air vent'l/i. The" flout chamber: is pyoviclelcl with a luel inlet '15) extending through This top 12. The fuel inlet is connec ted to u suitable Source fuel supply positioned below the devicll illustrated as is nu; usual in fuel stoma-oi the character under (lisaussion. pommunihaiion between the flout chamber and the feed chamber is provided by means oi a liquid discharge ou't-- le poi-h 16 poaifsionel l in the bottom of the no float chamber. Th9 hotlom of 'ihe i'ced chambur is provided With an outlet 17 which Y erebly ole-seal b x on Ty 3.1 #1 I r 4 I .e v .ve so. 100ml oi semi valves, eic upon 5;. connecting 2? and the VJu VES me ier unopened u, m clepenclieg upon the (lirection of movement of the stem. The ilout "be? is orcviclecl with flout 28 operthrough e system links 527 so that when the flout is at, or moving to or from its loweimost position both of the valves ciosetl. The links are loosely couuectecl to levers so that the initial upu movement of the float will have no effect on the position of the closed valves but as the fleet approaches the upper limit of its movement, it will react through the levers ancl reel to simultaneously open both oi the valves. lin general it will be understoocl that the construction as thus for deseribed resembles similar devices now lmown encl that the invention primarily resides in the ooiiihinetion of ospiratiug devices of the tyne hereinafter described for actuatj vity it'eerl tanks of the type hereinbefore described.

' Referring particularly to the attachmentat the top of the feed tank there is CllSGlOSRCl positioned on the top 12, or formed therewith, an esplretiiig device 32 which 111- eludes straight bore 33 extending therethrough from end to encl. The bore is (3011 strictesl intermediate lts ends to lorm s Veuturi tube The device is provifiecl with a relatively smell suction vent 35 open-- ing from the tube at 01' adjacent its point 36 of grez'ztest constriction. This vent pro vicles constantly openecl to the up' iier portion of the float chembein When the actuating pressure through. the Venturi tube is 2i gaseous fluul, it is pref emble that this vent be constantly opeueel, but under some conditions, as Where the Water of the cooling system is pusse l through this euturi tube, is suggested constantly t at it be necessaiiy to have some suiti zlisch "g'e e. {l the Venturi tube open to the outside air, if clesired,

may orsney lead to 21- niufitler or to the return pipe of the Water system indicated, diagrammatically by the pipe connection 38.

It 's found that the operation of the device is improved by positioning one or more beyond. the point 36 of 'rezviest cos n, which beffies apparently have the effect of breaking up the "fluid. pressure stream as it 18 passed through the Vcnturi tube. in Figure 1, one such baffle 39 1s member; also to remove the baffle this obtain access to the interior u .o Veiituri tube for the purpose of cleani r some.

- has been found experimentally that the greatest constriction is an improvement over the positioning of the vent beyond this point and for this reason the invention contemplates the positioning of thevent either at the point of greatest constriction as shown in Figure l or in advance of this point as shown in igure 3.

in order to adopt the device to operate with difi'erent pressures, the modified device shown in Figure 3 is'suggested. in this modification thetube 32 may, or may not be constricted, as desired and as governed by other "factors but the effective constriction is proviclecl by utilizing a replaceable nozzle 1-1 screwed into the intake end of the tube 32. charge nozzle ends 42 may be substituted for the nozzle illustrated. This form of replaceehleventuri forming nozzle is of further advantage in that it permits the ready removal of parts which are most likely to become clogged.

operation. it will be understood that the Venturi tube is constantly. connected to some available source of pressure and that the fluid, gaseous in some cases, or as suggeseeel, theliquid from the cooling system, is c nstantly fore-eel through the Vcnturi tube. thorcthrough it is'bi'oken up as is usual with injectors of this type and air is withdrawn from the float chumher through the open vent Assuming that the float is in its lowermost position and that the air inlet and the qliscliarge poi-tare closed, the actionof the uspiruting device will reduce the air pressure condition in the float chamber, thus unbalancingpressures on the luel and permitliin 'luel lobe elevated anddiscbarqeil' through the inlet and into the float charm her. The rising liquid in Yhe float chamber will set upon the Heat to ruise the same and "hus open the discharge portend air inlet.

Nothing more than oiciinai'y cure need; be exercised with i'eien sncs to the construction of the vaivcs for even if some air should leak through the valve controlling the air inie, i-a would meseiy mean u slight oieisy in the operation of she and any deiay due to a siighs leakage would be immaterial. Any avuiiable pressure, such as those suggesteci, acting through the Veninsi tube would be music to conipcnsuie for any such small ieaig, Again siicuici tiiere be a slight leak- .sg'e tiicougln she fuei controlling port is would nos materially ufiecfi; iviie opei'eiion of the device unci ,Woui-i merely mean that there was u sii ghs into the feeci oil-ember but this won in no way affect the economic actuation of we device,
