The valve 11 is provided with a valve stem 12 whiehlextends through a packing gland {1S and rigidly s'ecuredto a diaphragm 14' by means of disc-shaped members 15. Afcover '16 is provided for securing the diaphragm to the valve A and for providinga chamber "17. 7A bleeder valve 18? is disposed in com munication with the chamber 17 for var ting the speed at which the pressure passes rom A float valve is disposed in the tank 3 and consists of a tubular me nber lt) having a re- 'duced end 20 which extends through the bottomiof the tank 3Iand isin communication with the chamberl? by means of atube 21.

]A head 22is secured'to the upperporti'on ol the tubular member 19 and is providedwith avertically extending passageway 23 and a horizontally extending passageway 24 which communicates with the passageway 23. At thelower endofthe passageway23, thejhead 22 is provided with an outwardly extending annular valve portion 25; A valve seat 26 portion 215.77 Openings 27fare provided with in the lower portion of the valve seat 26. i l l 7 A sleeve 287is' slidably disposed upon the tubular memberflg and issecured to the valve 7 seat 26 by means of afstud 29 andan;a d- V justablenut 30. Openings 31 are disposed in the inner walls of the sleeve 28. Thelower end of the'sleeve 28 is providedwith an outwardly extending integral flange 32. A cam 33 which is actuated bya float 34 ispivot- 1 ally mounted at 35- to an "adjustable bracket Es PATENT OFFICE- f adapted to contact with the annular valve 9 36 and is in engagement with the flange 32.

Liquid control receptacles 37 are secured to the supply tubes 8 and 9 Within the tank The receptacles 37 are somewhat cylindrical in shape and are provided with concave upper ends 38, see Figure 2.

From the foregoing description of the various parts of the device, the operation thereof may be. readily understood. The carbonated water indicated at 39 passes from the carbonator to the gas control valve A and into the tank 3 under a certain amount of pressure. A portion of this pressure is maintained in the tank 3, the remainder escaping through a valve 40; When the level of the liquid in the tank 3 moves downwardly, the float 3A is lowered, thus actuating the cam and raising the sleeve 28. By raising the sleeve 28, the valve seat 26 is also raised into engagement with the annular valve 25, thus closing the passageway 23. In this manner, the air pressure in tank 3 is shut off from the upper portion of the diaphragm 14 and the pressure of the carbonated water is suiiicient to fully raise the valve 11 and the valve stem 12 upwardly, thus permitting the water to pass into the compartment 6, Without any substantial reduction of pressure, through the outlet openings 7 and 8 and through the tubes 9 and 10.

As the water passes from the tubes 9 and 10, it passes upwardly into the receptacles 37. The outlets of the receptacles 37 as indicated at Ll, are positioned close to the bottom of the tank 3 and beneath the level of the carbonated water 39 in the tank. Therefore, those portions of the receptacles above the level of the liquid therein form cushions. As the water passes from the tubes 9 and 10 into the receptacles, it strikes the gas cushions in the receptacles, thus checking the flow of the water and directing the same dmvnwardly through the outlet 41 and into the tank If the receptacles 37 were not used in connection with the tubes 9 and 10, the water passing from these tubes would be forced against the top of the tank 3 where it would splash in all directions. This splashing causes agitation of the carbonated water already in the tank, and a very pronounced liberation of gas would take place from the splashing water. This is obviated by the aid of the receptacles 37 and the water is passed into the tank without agitation, due

to the cushioning effect. thereof in the receptacles.

As the carbonated water'flows into the tank 3, the float 34 is raised upwardly, thus permitting the sleeve 28 to move downwardly and remove the valve seat 26 from the annular valve portion 25. In this manner, air pressure in tank 3 is permitted to pass through the openings 31, the passageways 24: and 23, around the valve seat 26, through the open- I ings-27, through the tubularportion 19, the

tube 21, and into the chamber 17. The diaphragm 14 being greatly larger in diameter than the opening 4 permits a movement clownwardly of the valve 11 against the relatively high pressure of the carbonated water with a relatively small amount of air pressure. In this manner, the valve 11 is held closed preventing carbonated water from entering the tank-until the float 34: again moves downwardly. The motion of valve 11 is very rapid in closing and opening, therefore no wiredrawing.

Vith this construction, the carbonated water is permitted to pass smoothly from the carbonator through the valve A when the valve 11 is opened, through the tubes 9 and 10, and into the tank 3 by way of the receptacles 37 without causing agitation of the carbonated water and therefore practically no loss of Hence, a relatively low carbonator pressure is required to get the same number of gas volumes in the finished beverage as was heretofore obtained with a much higher carbonator pressure.

We claim:

A device of the type described comprising a housing having a liquid inlet and a liquid outlet, a valve disposed in said housing and arranged to be moved into engagement with said liquid inlet, a valve stem secured to said valve, a diaphragm secured to said valve stem and carried by said housing, an air compartment disposed in said housing on one side of said diaphragm for receiving air under pressure for closing said valve, means for releasing the air under pressure from said air compartment, whereby a liquid under pres sure may open said valve and pass through said inlet and said outlet, a filling tank, communication between said filling tank and said outlet for receiving the liquid from said out let, and a receptacle disposed in said tank in alignment with the communication with said outlet and extending above the liquid in said tank for cushioning the liquid as the liquid is forced into said tank.
