  • a pressure control valve 28 which is connected to the cap 30 of the pressurized carbon dioxide container 14.
  • the pressure in the container 14 could be as high as, for example, 1800 to 2000 PSI.
  • the pressure regulating valve 28 reduces the pressure flow from the container 14 to a constant 200 PSI.
  • the valve assembly 18 comprises the aforementioned pressure control valve 28, a pressurizing valve 32 having an actuating ball element 34, also a venting valve 36 having its related actuating ball member 38, and a valve actuating means 39.
  • the valve actuating means 39 comprises the aforementioned actuating knob 26 and an actuating cam 40 which is connected to a vertically moveable actuating member 42 (shown only schematically) .
  • the aforementioned actuating knob 26 is fixedly connected to the actuating member 42.
  • the pressure control valve 18 and the pressurizing valve 32 can be considered to comprise a pressurizing and pressure control valve means, while the pressurizing valve 32 and the vent valve 36 can be considered as a pressurizing and venting valve means.
  • the actuating knob 26 is in its lower position so that the cam member 40 is positioned so that it bears only against the venting valve member element 38 so that the valve element 36 is in its venting position.
  • the cam member 40 in its lower position, is not in engagement with the pressurizing valve element 34, so that this pressurizing valve 32 remains closed.
  • the venting valve 36 connects through a line
  • the initiating of the carbonating step is accomplished simply by raising the actuating knob 26 upwardly which in turn raises the actuating member 42 with its cam 40 upwardly.
  • Figure 2B shows the actuating member 42 in an intermediate position where the cam member 40 is moving upwardly to a position where the flat cam surface 60 has depressed both of the valve actuating members 34 and 38.
  • the venting valve 36 remains open (as it was in the position of Figure 2A) , but in addition the pressurizing valve 32 also moves to its open position.
  • the pressurized carbon dioxide in the container 14 first passes through a pressure reduction valve 28 to regulate the pressure at a constant 200 PSI.
  • the pressurized carbon dioxide flows through the line 62 through the pressurizing valve 32 which is now open, thence through the line 64 to pass into the pressurizing opening 66 in the lid and injector assembly 20.
  • the pressurized carbon dioxide moves through the pressurizing opening 66 downwardly through an injection tube 68 which is fixedly connected to the lid and injection assembly 20.
  • the carbon dioxide exits from the tube 68 through a lower end nozzle 70 which is spaced a short distance upwardly from the bottom 72 of the container 16.
  • the nozzle 70 has a single discharge orifice of a relatively small diameter, so that the carbon dioxide is discharged as a very fine gaseous spray.
  • the carbon dioxide bubbles flow upwardly in the water 54 to give the water a somewhat milky appearance.
  • the actuating member 40 When the desired amount of carbon dioxide has been injected into the container 16 which is now at about 200 PSI, the actuating member 40 is moved downwardly. Thus, the cam member 40 will first move downwardly to the position of Figure 2B. At this time, the venting valve 36 opens, by its actuating member 38 being depressed, and when the actuating member continues to be moved further downwardly to the position of Figure 2A, the venting valve 36 remains open, while the pressurizing valve 30 is closed. The result of this is that the carbon dioxide that is in the upper empty container portion 58 and whatever air might remain simply vent out through the passageway 44 and outwardly through the venting valve 36 to atmosphere.
  • the door 22 is opened, and the container 16 (still connected to the lid and injector assembly 20) is removed from the injecting chamber 24.
  • the lid and injector assembly 20 is unscrewed from the container 16.
  • a conventional cap could then be placed over the opening of the container 16 to maintain the water 54 as carbonated.
  • a syrup could first be poured into the container opening and then mixed with the carbonated water 54 by turning the container 16 to an inverted position and back to its upright position several times. The carbonated beverage in the container 16 could then be stored or consumed.
  • one of the objects of the present invention is to provide for the reliable and safe operation of the apparatus 10.
  • an interlock system 74 which is incorporated with the actuating member 42 of the valve assembly 18 and also in the door 22.
  • This interlock system 74 is arranged so that with the door 22 open, the valve actuating member 42 cannot be raised to open the pressurizing valve 32. But when the door 22 is closed, the valve actuating 42 can be raised, and at the same time the door 22 is locked shut until the valve actuating member 42 is lowered.
  • the swing end 78 of the door 22 has a "J" shaped locking and release arm 80 mounted at the swing end.
  • This arm 80 accomplishes two functions. First, it moves a release arm 82 a short distance rearwardly to a release position to permit the upward movement of the valve actuating member 42, so that the release arm 82 is able to pass by a stationary stop member 83 mounted to the housing 12. Also, an end finger 84 of the arm 80 causes the door 22 to be locked in its closed position when the actuating member 42 is raised so that a laterally extending locking finger 86 that is mounted to the actuating member 42 moves upwardly into engagement with the finger 84. Also, when the actuating member 42 is moved upwardly, the interlocking member 86 comes into abutting engagement with the member 83 to limit the upward travel of the actuating member 42.
  • the actuating knob 26 is connected by two or more screw members 88 to a U shaped frame member 90 of the actuating member 42 which in turn is constrained to move against inwardly extending walls 92 of the valve housing 12.
  • Figure 7A the actuating member 42 is in its down position. The door 22 has not been closed. Thus, the retaining and release finger 82 remains in its forward position where its finger portion 94 is immediately below the stop member 83. In this position, the actuating member 42 cannot be raised.
  • FIGs 8A, 8B and 8C show the operation of this interlocking mechanism.
  • the stop members 86 are disengaged from the lips 84 of the two "J" arms 80.
  • the interlocking members 86 are coming into locking engagement, and this engagement is complete in Figure 8C.
  • Another locking mechanism is shown with reference to Figure 8A, 8B and 8C. It can be seen that there is an upper locking arm 95 which is pivotally mounted at 96 to the housing 12. The left end of the arm 95 has a pivot connection at 98 to the upper end of the actuator 42, and the opposite end of the arm 95 has a downwardly extending locking finger 100. This finger 100 reaches through an opening in an upper housing wall portion 102 that defines the upper part of the chamber 24.
  • This assembly 20 comprises a mounting plug 108 which has a pair of side flanges 110 so that this plug 108 can be slid into a receptacle block 112, having a top wall 114 and two side walls 116, with the side walls 116 having two longitudinally extending lips 118 to engage the flanges 110 of the block 108.
  • the pressurizing line 66 and the venting line 46 connect to related fittings 120 and 122, respectively, which in turn lead into male elements 124 and 126 that interfit with related receptacles 128 and 130 in the block 110.
  • the receptacle 128 leads through a line 132 to discharge pressurized carbon dioxide through an opening 134 into the discharge tube 68.
  • the receptacle 130 connects to a passageway 136 which connects to the vent opening 138.
  • the lower part of the plug member 108 is formed with a closure cap portion 140 which is interiorly threaded at 142 so that this can be screwed onto matching threads 144 at the top of the container 16.
  • Figure 12 shows the container 16 in side elevation. It will be noted that an upper portion 142 of the container 16 tapers upwardly in the form of a truncated cone. There are lateral marking lines 144 on the side of the upper container portion 142 to indicate the level to which the water should be poured into the container 16, depending upon the syrup or other additive which is to be added to the water in the container 16 after it has been carbonated.
  • Figure 13 is a rear view of the apparatus 10. There is a rear door 146 through which the pressurized carbon dioxide container can be placed and removed. Also, there are a plurality of plug members 148 mounted to a back wall 150 of the housing 12.
  • FIG. 14 A second embodiment of the present invention is shown in Figure 14. Components of the second embodiment which are similar to the first embodiment will be given like numerical designations, with an "a" suffix distinguishing those of this second embodiment.

  • This second embodiment has (in addition to all of the other components of the first embodiment) a venting orifice member 160 which is connected to the vent line 44a at a location between the vent valve 36a and the lid and injection assembly 20a.
  • a tube 162 is shown connecting the orifice member 160 with the line 44a, and the vent orifice itself is indicated at 164.
  • the effective size of the discharge passageway in the orifice 164 is about the same size as, or moderately smaller than the effective size of the orifice in the injection nozzle 70a. In one arrangement which has been proven to be satisfactory, the diameter of the orifice of the discharge nozzle 70a is 0.020 inches in diameter, while the venting orifice 164 in the vent orifice member 160 is 0.0147 inch in diameter.
  • the size of the vent orifice is somewhat larger and specifically is 0.0160 inch in diameter. In yet another arrangement the orifice sizes are nearly equal, or the vent orifice 64 could actually be made moderately larger.
  • the overall operation of this second embodiment of Figure 14 is substantially the same as described in the first embodiment, in that the bottle 16a is filled with liquid, and the mounting plug 108 of the lid and injector assembly 20 is connected to the top of the bottle 16 and placed in the injection chamber 24. The door is closed, and the actuating cam member 42a is raised to open the pressurizing valve 32a and cause carbon dioxide to flow through the line 68a and through the orifice of the discharge nozzle 70a. At this time, the vent valve 36a is closed.
  • the pressure regulating valve 28a reduces the pressure of the carbon dioxide flowing from the container 14a to a suitable level, which has been indicated herein as 200 psi. There is possibly an initial
  • the absolute pressure in the line 64a and through the tube 68a would be approximately 205 psi. Accordingly, the initial flow through the orifice in the nozzle 70a would be at its iticLximum, and would remain substantially constant until the absolute pressure level within the container 16a reaches an absolute pressure level possibly in the range of 80 to 110 psi absolute. Then the flow through the orifice of the discharge nozzle 70a will become subsonic, and the flow thereafter will be in accordance with the Bernouli's law and continue to decrease as the pressure level rises further in the liquid container 16a.
  • the volumetric flow of the carbon dioxide out of the orifice of the nozzle 70a is greater than the outflow through the vent orifice 164, so that the pressure inside the container 16a continues to rise.
  • the volumetric flow through the orifice in the nozzle 70a remains constant, while the pressure in the line in the lines 44a and 162 increases so that the flow out the vent orifice 164 increases.
  • the vent valve 36a is closed.
  • the pressure differential across the orifice 70a has dropped to a sufficiently low level and the pressure drop across the vent orifice 164a has risen to a sufficiently high level, so that the volumetric flow through the vent orifice 164 equals (or nearly equals) the volumetric flow through the nozzle 70.
  • this balance of carbon dioxide flow into the container 16a and out the vent orifice 140 is reached when the pressure level in the lines 44a has reached 150 psi gauge pressure, as indicated in the pressure gauge 50a connected to the line 44a.
  • the size of the orifice 164 could be made greater relative to the size of the orifice in the nozzle 70a so that the flow through the orifice 164 would be equal to the flow through the orifice in the nozzle at a lower pressure level in the container, so that the water would be pressurized to a lower level (e.g. 80 to 100 psi) to complete the carbonization process.
  • the actuating cam 42a is lowered to disengage the pressurizing valve 32a (thus closing off further flow of carbon dioxide to the container 16a) and the valve control ball member 38a is engaged to open the vent valve 36a. This causes the pressure in the line 44a and in the container 16a to drop rather quickly.
  • the container 16a is removed from the injection chamber in the apparatus 10a, and the lid and injector assembly 20a is removed from the bottle 16a as in the first embodiment, and the further steps are taken as described with regard to the first embodiment.
  • a third embodiment of the present invention is shown in Figure 15. Components of this third embodiment which are similar to components of the second and first embodiment will be given like numerical designations, with a "b" suffix distinguishing those of the third embodiment.
  • This third embodiment is the same as the second embodiment, except that the vent valve 36a has been eliminated.
  • the actuating cam 40b is moved downwardly to close the pressurizing valve 32b. With the pressurizing valve 32b being closed, the further pressure drop in the container 16b would depend solely on the rate of discharge through the vent orifice 164b.
  • This arrangement of the third embodiment is, from an operational view, less desirable than that of the second embodiment, because of the delay in reducing the pressure within the container 16b. Also, with this arrangement of the third embodiment of Figure 15, when the valve actuating member 42b is lowered to unlock the door, the container 16b would not become immediately depressurized. Accordingly, an alternative interlock mechanism should possibly be provided.
  • a fourth embodiment is shown in Figure 16. Components of this fourth embodiment which are similar to components of the first three embodiments will be given like numerical designations, with a "c" suffix distinguishing those of this fourth embodiment.
  • This fourth embodiment is substantially the same as the second embodiment, and thus in addition to the components of the first embodiment, also comprises the vent orifice member 160c, a connecting tube 162c, and the vent orifice 164c.
  • a pressure relief valve 166 connecting to the line 162c, so as to be in parallel with the vent orifice 164c.
  • This pressure relief valve 166c operates, as its name implies, to provide pressure relief in the event of an overpressure in the line 162c.
  • this pressure relief valve 166 can be provided with an audible signal mechanism (indicated schematically at 168) which is activated when the pressure relief valve 166 moves to its open position.
  • the pressure relief valve 166 opens to cause pressurized flow of carbon dioxide through the valve 166 to activate the audible signal mechanism 168.
  • a fifth embodiment is illustrated in Figure 17.
  • Components of this fifth embodiment which are similar to components previously described herein will be given like numerical designations, with a "d" suffix distinguishing those of the fifth embodiment.
  • a vent orifice member I60d with a connecting tube 162d and the vent orifice 164d.
  • a pressure relief valve 166d As in the fourth embodiment, there is also provided a pressure relief valve 166d.
  • the pressure relief valve 166d is connected in series with the vent orifice member 160d.
  • the vent orifice member I60d discharges the carbon dioxide into the chamber 170 which is defined by an expanded tubular portion 172, having an inlet at which the vent orifice member 160d is positioned, and an outlet at which the pressure relief valve 166d is positioned.
  • the pressure relief valve 166d in series modifies the operation from what is disclosed in the second, third and fourth embodiments.
  • the pressure relief valve 166d would be selected so that it opens to atmospheric pressure at a pressure level between atmospheric pressure and the desired end pressure at which the carbonization of the liquid in the container I6d would stop.
  • the pressure valve 166d could be caused to open at a pressure level of, for example, 75 psi.
  • the effective flow area of the vent orifice 164d would be enlarged slightly relative to the effective flow area of the orifice in the pressurizing valve 70d. This will be explained below relating to the operation of this fifth embodiment.
  • the container 16d has been placed in its operating position, and the valve actuating member 42d has been raised to its position to open the pressurizing valve 32d.
  • the carbon dioxide from the container 14d begins to flow into the container 16d, and as the pressure rises in the container 16d, there is flow of carbon dioxide through the line 44d in the connecting line 162d to cause a certain amount of flow through the vent orifice 164d, into the chamber 170d.
  • the chamber 170d is, in Figure 16, shown much larger than it would actually be, and in an actual operation, the volume of the chamber 170 would be a very small fraction of the volume of the entire container 16, (and actually a small fraction of the volume of the interior chamber of the container that is above the level of the liquid) .
  • the effect of this is that the pressure differential across the vent orifice 164d would not need to be very large to cause a sufficient volumetric flow through the orifice 164d to maintain the pressure within the chamber 170 reasonably close to the pressure level in the container I6d.
  • vent orifice 14d and the volume of the chamber 170 is such that with the vent relief valve 166d closed, the pressure in the chamber 170d rises to 75 psi gauge pressure at such time as the pressure in the container 16b rises to, for example, 80 or 85 psi.
  • the pressure relief valve I66d would open, and provide a flow discharge passage having an effective cross sectional flow area many times greater than that of the orifice 164d.
  • the apparatus of this fifth embodiment of Figure 17 is operating in substantially the same manner as the second embodiment of Figure 14, except that instead of venting the orifice 164 of the second embodiment to atmosphere, the present embodiment vents the orifice 164d to a chamber at an intermediate level between atmospheric and the pressure in the container 16d.

Abstract

L'invention concerne un système de carbonatation de l'eau, utile pour la fabrication d'une boisson gazeuse. Le système comprend un logement destiné à recevoir une bouteille de gaz carbonique sous pression et également pour constituer une chambre destinée à recevoir un récipient d'eau. Une vanne de régulation de la pression maintient la sortie du gaz carbonique sortant du récipient de gaz carbonique à une pression prédéterminée inférieure et dirige le gaz carbonique vers une valve de pressurisation à fonctionnement sélectif qui dirige le gaz carbonique par une buse de sortie dans l'eau du récipient. Le récipient d'eau est fermé par un bouchon monté en communication avec un bloc récepteur, lequel est sélectivement en communication avec la valve de pressurisation et est également sélectivement en communication avec une valve de mise à l'air fonctionnant sélectivement pour évacuer le gaz carbonique sous pression restant après la fin de la carbonatation. Dans plusieurs formes d'exécution, on prévoit également un orifice de mise à l'air pour évacuer d'une manière continue le gaz carbonique du récipient d'eau, à mesure que le gaz carbonique est injecté dans l'eau, afin d'obtenir une carbonatation plus complète.
