Abstract
Abstract A two-stage carbonator for carbonating fluids in a single chamber having a venting system by which the chamber is at least partially vented of pressure to allow entry of fluid from a lowpressure line. The pressurized gas inlet directs the stream of gas tangentially to the liquid outlet through a normally open valve. The gas stream is thus directed into the chamber during discharge and passes adjacent the discharge opening thereby supercharging the exiting fluid, increasing the degree of carbonation.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
18 words
The carbonator of claim 1 wherein the gas stream is directed to one side of the dispensing opening.
Claim 2
Dependent Claim
16 words
The carbonator of claim 2 wherein the gas stream is directed tangentially to the dispensing opening.
Claim 3
Dependent Claim
186 words
A carbonator for carbonating fluids comprising: a pressure vessel mixing chamber, a vent connected to said chamber adapted to vent the interior thereof to the atmosphere, a fluid source connected with said mixing chamber adapted to supply fluid thereto, a relatively high pressure gas source connected to said mixing chamber and adapted to supply pressurized gas thereto, a dispensing opening in said chamber adapted to withdraw fluid from the interior thereof, means for closing the vent, means for shutting off flow of fluid to the mixing chamber, means for shutting off flow of pressurized gas to the mixing chamber, means for stopping withdrawal of fluid from the mixing chamber, means for controlling the vent means and gas means, and means for adding carbonation to fluid being withdrawn from the chamber throughout said dispensing opening, the inlet conduit from the gas souRce terminating in relatively close spaced relation to the dispensing opening, the gas stream from the conduit being directed at the dispensing opening such that the fluid stream from the chamber through the dispensing opening partially intersects the relatively high pressure gas stream from the conduit.
Claim 4
Independent Claim
234 words
A device for adding carbonation to a fluid comprising: a pressure vessel mixing chamber; a vent for said chamber; a fluid supply system for said chamber; a pressurized gas supply system for said chamber; a dispensing system for said chamber; first valve means adapted to open and close said vent; second valve means adapted to open and close said fluid supply system; third valve means adapted to open and close said gas supply system; fourth valve means adapted to open and close said dispensing system; first control means; said first control means responsive to actuation of said fourth valve means; said first control means adapted to override a second control means; said second control means responsive to fluid level in said chamber; said second control means adapted to control said first and third valve means; said second valve means responsive to pressure in said chamber adapted to supply fluid to said chamber in the absence of pressure in said chamber; said first control means effective to continue supply of gas through said gas supply system to said chamber during dispensing of fluid from said chamber through said dispensing system; said dispensing system having a dispensing opening in said chamber; said pressured gas supply system terminating in said chamber adjacent said dispensing opening; and said termination of said gas supply system effective to add carbonation to the fluid being dispensed from said chamber during dispensing.
Claim 5
Independent Claim
148 words
The method of carbonating a fluid in a mixing chamber which comprises: providing a fluid in said chamber, adding a relatively highly pressurized carbonating gas to said chamber until a desired pressure is achieved in said chamber thereby carbonating the fluid in said chamber to a first level of carbonation, terminating the supply of fluid to said chamber, dispensing a portion of said fluid from said chamber through an opening in said chamber, supplying an additional amount of said relatively high pressure gas to said chamber in a gas stream during dispensing of said portion of said fluid, supplying said additional gas adjacent said opening, the gas stream at least partially intersecting with the fluid stream exiting through said opening and dissolving a portion of said additional gas in the fluid being dispensed through said opening thereby raising the carbonation of said dispensing fluid to a second level.
Claim 6
Dependent Claim
17 words
The method of claim 6 wherein said additional amount of gas is supplied tangentially to said opening.
Claim 7
Independent Claim
123 words
A method of adding carbonation to a carbonated fluid which comprises: containing a carbonated fluid in a chamber, providing a dispensing opening in the chamber, withdrawing a portion of the fluid from the chamber through the opening, providing a stream of relatively high pressure carbonating gas within the chamber adjacent the opening during withdrawal of said portion, providing said stream of relatively high pressure carbonating gas at a point in the chamber positioned relative to the opening whereby the exiting stream of relatively high pressure gas intersects with a portion of the fluid flow stream of said carbonated fluid flowing towards and through the said opening during withdrawal, and dissolving a portion of said gas in the fluid being withdrawn through the opening.
Claim 8
Dependent Claim
15 words
The method of claim 8 wherein the gas stream is provided tangentially to said opening.
Claim 9
Dependent Claim
33 words
The method of claim 8 wherein the remainder of the gas in said stream is contained in the chamber to pressurize the chamber to aid in forcing of fluid out of the opening.
Claim 10
Dependent Claim
29 words
The carbonator of claim 4 wherein an adjustable pressure regulator is connected tO said vent effective to retain a selected pressure in said chamber when said vent is opened.
Claim 11
Dependent Claim
46 words
The device of claim 5 wherein an adjustable pressure regulator is connected to said vent effective to selectively retain a desired pressure in said chamber less than the pressure in the said fluid supply system when said first valve means is positioned to open said vent.
