Abstract
Abstract An inline water carbonator introduces CO2 and fresh water into a conduit leading to a carbonated water dispensing valve each time the valve is opened. The CO2 and water are thoroughly mixed in the conduit as the carbonated water is dispensed through the valve so that the water is charged with CO2 when it is dispensed.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
110 words
A liquid and gas mixing and dispensing system comprising a source of liquid under pressure, a source of gas under pressure, a dispensing valve, means forming a conduit for delivering water and gas from said sources to said valve, said conduit means having an inlet connected with said liquid source and an inlet connected with said gas source, means responsive to opening of said dispenser valve to provide a gas pressure at said conduit liquid inlet less than the pressure of said liquid source, and means to provide an increase in gas pressure at said conduit higher than said liquid source pressure in response to closing of said dispenser valve.
Claim 2
Dependent Claim
110 words
A liquid and gas mixing and dispensing system comprising a source of liquid under pressure, a source of gas under pressure, a dispensing valve, means forming a conduit for delivering water and gas from said sources to said valve, said conduit means having an inlet connected with said liquid source and an inlet connected with said gas source, means responsive to opening of said dispenser valve to provide a gas pressure at said conduit liquid inlet less than the pressure of said liquid source, and means to provide an increase in gas pressure at said conduit higher than said liquid source pressure in response to closing of said dispenser valve.
Claim 3
Dependent Claim
19 words
A liquid and gas mixing and dispensing system as defined in claim 1 in which the liquid is water.
Claim 4
Dependent Claim
19 words
A liquid and gas mixing and dispensing system as defined in claim 1 in which the gas is CO2.
Claim 5
Dependent Claim
24 words
A liquid and gas mixing and dispensing system as defined in claim 1 in which the liquid is water and the gas is CO2.
Claim 6
Dependent Claim
66 words
A liquid and gas mixing carbonating and dispensing system as defined in claim 1 further characterized by means to maintain the pressure of gas at said gas source appreciably higher than the pressure at said liquid source, and pressure reducing means in said conduit means between said inlets for reducing the pressure of gas flowing into said conduit means below the pressure of said liquid source.
Claim 7
Dependent Claim
40 words
A liquid and gas mixing and dispensing system as defined in claim 5 further characterized by said pressure reducing means comprising a restricted orifice in said conduit means between said inlet connected with said gas source and said liquid source.
Claim 8
Dependent Claim
32 words
A liquid and gas mixing and dispensing system as defined in claim 6 further characterized by a check valve between said liquid source and said conduit inlet connected with said liquid source.
Claim 9
Dependent Claim
34 words
A liquid and gas mixing and dispensing system as defined in claim 6 further characterized by a check valve between said source of gas and said conduit inlet connected with said source of gas.
Claim 10
Dependent Claim
33 words
A liquid and gas mixing and dispensing system as defined in claim 1 further characterized by means in said conduit means downstream from said inlets for agitating fluid passing to said dispensing valve.
Claim 11
Dependent Claim
49 words
A liquid and gas mixing and dispensing system as defined in claim 9 further characterized by said means for agitating fluid comprising tubular wall sections having perforations through said wall sections, and means to direct the flow of fluid in alternate directions through the perforations in alternate wall sections.
Claim 12
Dependent Claim
24 words
A liquid and gas mixing and dispensing system as defined in claim 10 in which certain of said tubular segments comprise cylindrical screen material.
Claim 13
Dependent Claim
24 words
A liquid and gas mixing and dispensing system as defined in claim 10 further characterized by one of said tubular wall sections being conical.
Claim 14
Dependent Claim
30 words
A liquid and gas mixing and dispensing system as defined in claim 12 further characterized by said conical section being the first of said wall sections downstream of said inlets.
Claim 15
Dependent Claim
84 words
Apparatus as defined in claim 9 further character-ized by said means in said conduit comprising a series of tubulAr segments extending along the inside said conduit and having a multiplicity of openings through the side walls thereof and arranged with said walls spaced from the inner walls of said conduit, and means forming baffles to direct fluid flowing through said conduit inwardly and then outwardly through the wall openings in alternate sections of said tubular segments at least one of said sections being conical.
Claim 16
Dependent Claim
44 words
A liquid and gas mixing and dispensing system as defined in claim 9 further characterized by said means for agitating fluid comprising a conical member arranged axially in said conduit and comprising a wall having a plurality of apertures through which said fluid passes.
