  • the three-way vent valve 63 is manually operable to control the pressurization or depressurization of the gas chamber 58 of the water tank 52.
  • the three-way vent valve 63 When switched to an open position, the three-way vent valve 63 directs high pressure CO 2 gas into the gas chamber 58 of the water tank 52 which urges the pliable diaphragm 54 against the volume of water contained in the water chamber 56 to increase the pressure of the water to a level within the range of approximately between 195 psi to 200 psi.
  • the three-way vent valve 63 When the operator wishes to refill the tank 52 with water, the three-way vent valve 63 is manually switched to a closed position in which the supply of high pressure CO 2 gas to the tank 52 is shut-off and the high pressure gas contained in the gas chamber 58 of the water tank is vented to the atmosphere to relieve the pressure therein.
  • this gas is first directed to a first vent line 65 which leads to a diffuser 67 which, as is known in the art, gradually diffuses the vented gas into the atmosphere to reduce noise.
  • a diffuser 67 which, as is known in the art, gradually diffuses the vented gas into the atmosphere to reduce noise.
  • the water supply line 60 further is used to transport the pressurized water in two separate directions.

Coupled with a pneumatic signal line 66, the water valve 64 and water level switch 40 are in fluid communication with one another.
  • the water valve 64 When supplied with a pneumatic pressure signal sent from the water level switch 40, the water valve 64 opens, permitting high pressure water supplied by the water tank 52 to pass through the valve and into a carbonator tank supply line 68. In use, the water is transported into the tank 16 through a water inlet check valve 70 that is mounted to the carbonator tank.
  • the water supply line 60 transports high pressure water in a second direction to a water pressure regulator 72.
  • This pressure regulator 72 reduces the pressure of the water supplied from the water tank to approximately 45 psi to 60 psi. From the water pressure regulator 72, the water flows through a flat water supply line 74 and then through the cold plate 48 to be dispensed by the beverage. dispensing valve 18 when activated by the operator.
  • FIG. 2 illustrates, in cut-away view, the carbonator tank 16 preferred for use in the embodiment shown in FIGS. 1-12.

  • first and second signal lines 236 and 238 are also connected to the pump 200 on the gas side 196 of the system 45.
  • the first signal line 236 is in fluid communication with the first proximity sensor 226 and the second signal line 238 is in fluid communication with the second proximity sensor 228.
  • the first and second signal lines 236 and 238 similarly connect to the master control valve 230.
  • the proximity sensors 226, 228 further are in fluid communication with a sensor gas supply line 240.
  • This sensor gas supply line 240 is connected to a main gas supply line 242 that receives CO 2 gas at approximately 45 psi from the second pressure regulator 28.
  • the gas side 196 further includes a vent line 244 which extends from the master control valve 230 to the first vent line 65 (FIG. 1). As indicated in FIG. 1, this vent line 244 normally includes a check valve 246 that is placed between the pneumatic pump system 45 and the diffuser 67 such that high pressure gas venting from the water tank 52 cannot be transported directly to the pneumatic pump system 45.
  • the double acting pump 200 includes an air supply line 248 that, as shown in FIG. 1, is connected to an air filter 250.
  • the air supply line 248 is connected to first and second air passage lines 250 and 252 that connect to the pump 200 at its first end 204 and adjacent the central dividing member 208, respectively.
  • the air side 198 of the pneumatic pump system 45 further includes an air output line 254 that, like the air supply line 248, is connected to two air passage lines, namely a third air passage line 256 and a fourth air passage line 258.
  • a check valve 260 Positioned intermediate each of the air passage lines is a check valve 260 which ensures that air can pass through the lines only in a single direction.
  • pressurized CO 2 gas exits the second pressure regulator 28 and travels down supply line 42 to the pneumatic pump systems main gas supply line 242.
  • the main gas supply line 242 transports this gas to the master control valve 230 which, in turn, either directs this gas into the first gas supply line 232 or the second gas supply line 234, depending upon the desired direction of travel of the second piston head 222.
  • the gas supplied by the main gas supply line 242 is directed into the second gas supply line 234 and, thereby, into the gas chamber 212 adjacent the second end 206 of the pump outer tube 202.
  • this gas collects in the gas chamber 212, its pressure urges the second piston head 222 toward the air side 198 (upward in FIG. 11).
  • this axial displacement of the second piston head effects a similar axial displacement of the first piston head.
  • the air in the air chamber 210 is forced outwardly from the outer tube and into the third air passage line 256 such that this air can travel through the check valve 260 and into the air output line 254, and finally into one or more of the liquid containers 44 (FIG. 1).
  • fresh air is provided to the air chamber 210 behind the first piston head 220 with the second air passage line 252.
  • air from the atmosphere is taken in through the air filter 250 and supplied to this second air passage line 252 with the air supply line 248.
  • the piston head makes contact with the first proximity sensor 226.
  • the piston head depresses a valve needle 262 of the proximity sensor to send a pneumatic signal along the first signal line 236 to the master control valve 230 to cause the control valve to redirect the high pressure gas supplied by the main gas supply line 242 from the second gas supply line 234 to the first gas supply line 232 so as to urge the second piston head 222 in the opposite direction.
  • the gas in front of the piston head is evacuated through the second gas supply line 234 (which previously had supplied high pressure gas to the gas chamber 212).
  • the gas evacuated in this manner through the second gas supply line 234 is directed within the master control valve 230 to the vent line 234 such that this evacuated gas can pass through the check valve 246 and eventually through the diffuser 67 and out to the atmosphere (FIG. 1).
  • travel of the second piston head 222 effects similar travel of the first piston head 220.
  • the first piston head 220 now travels toward the central dividing member 208.
  • the air within the air chamber 210 is forced outwardly from the outer tube 202 this time through the fourth air passage line 258, through its check valve 260, and finally out through the air output line 254.
  • first and second air passage lines 250 and 252 are reversed, i.e ., the first air passage line 250 provides fresh air to the air chamber 210, and the second air passage line 252 is closed by its check valve 260.
  • the pneumatic pump system 45 supplies pressurized air to one or more of the containers 44 such that the liquid contained therein will be urged outwardly therefrom when this liquid is needed. In that air is supplied to these containers 44 as opposed to gas, carbonation of the liquid within these containers is avoided. Accordingly, the pneumatic pump system 45 is particularly useful for pressurizing containers 44 that contain liquids for non-carbonated drinks such as juices and juice concentrates. It is to be noted, however, that the pneumatic pump system 45 can be used to pressurize all of the containers 44 of the system, if desired.
  • the first embodiment of the beverage dispensing system 10 can be used to dispense carbonated and noncarbonated mixed beverages, as well as any carbonated and noncarbonated unmixed beverages, in liquid form.
  • the water tank 52 is filled with water via the water tank refill check valve 62 and water supply line 60.
  • the three-way vent valve 63 is manually switched to the gas open position such that the gas chamber 58 of the tank and the supply line 50 are in open fluid communication with one another.
  • the operator opens the shut-off valve 22 of the gas storage tank 20 so that high pressure CO 2 gas flows to the three gas pressure regulators 26, 28, and 30.
  • CO 2 gas flows into the carbonator tank 16, raising the pressure within the tank to approximately between 90 psi to 110 psi.
  • this gas is directed to the fourth pressure regulator 35 which then delivers the gas to the water level switch 40.
  • the gas supplied to the water level switch 40 is used, as needed, to send pneumatic pressure signals to the water valve 64.
  • the high pressure CO 2 gas also flows through the second and third pressure regulators 28 and 30. After passing through the third pressure regulator 30, the high pressure gas passes through the supply line 50, through the three-way vent valve 63, and into the gas chamber 58 of the water tank 52 to fill and pressurize the water within the tank.
  • the water is forced out of the tank 52 and flows through the water supply line 60 to travel to both the carbonator tank water valve 64 and the water pressure regulator 72.
  • the water that passes through the water pressure regulator 72 is routed into and through the flat water supply pipeline 74 to be cooled by the cold plate 48 and, if desired, dispensed through the beverage dispensing valve 18.
  • the float member 88 contained therein is positioned near the bottom of the tank and the water tank level switch 40 is in the activated position shown in FIG. 3. Because the water tank level switch 40 is in this activated position, pneumatic pressure is provided to the water valve 64, keeping it in the open position so that water can flow into the carbonator tank 16. As the water continues to flow from the water tank 52 and fills all lines connected thereto, the pressure of the water begins to rise sharply. Eventually, the pressure of the water in the water chamber 56 and the lines in fluid communication therewith reach a pressure equal to that of the high pressure CO 2 gas contained in the gas chamber 58. Accordingly, water enters the carbonator tank 16 at high pressure, typically between 195 psi to 200 psi.
  • the carbonator tank 16 Since the carbonator tank 16 is relatively small when compared to the CO 2 container and water tank, it fills quickly. Therefore, carbonated water is available soon after the system 10 is initiated. As such, the operator can use the beverage dispensing valve 18, commonly referred to as a "bar gun,” to dispense either flat water supplied by the flat water supply line 74 or carbonated water supplied by the carbonated water supply line 82.
  • the water level switch 40 becomes oriented in the inactivated position (FIG. 4), thereby shutting-off the supply of gas to the water valve 64. Not having the pressure signal needed to remain open, the water valve 64 closes, cutting the supply of water to the carbonator tank 16. As the water level within the carbonator tank 16 is again lowered, the water level switch 40 is again activated, restarting the process described above.
  • the system 10 therefore cycles in response to the volume of water contained in the carbonator tank. The cycle occurs repeatedly during use of the system 10, until either the gas or water supplies are depleted. At this time, either or both may be refilled, and the system 10 reinitiated.
  • the pressurization and supply of the liquid contained in the containers 44 is effected under the influence of pressurized CO 2 gas.
  • CO 2 gas at approximately 45 psi travels from the supply line 42 directly to one or more containers 44.
  • these containers 44 will contain liquids that are to be used in carbonated drinks, such as soft drink syrups.
  • the supply line 47 is opened to the valve and the liquid flows from its container 44, under the pressure of the CO 2 gas, to the dispensing valve.
  • the CO 2 gas travelling along the supply line 42 also is directed to the pneumatic pump system 45 which, as described in detail above, pressurizes air and supplies it to selected containers 44. Normally, these containers contain liquids used to make non-carbonated drinks such as juices and the like.
  • the pump 200 of the pump system 45 will continue to cycle back and forth in response to the activation of the proximity sensors 226, 228 until equilibrium is reached between the air chamber 210 and the interior of the bottles 118 that are pressurized therewith. At this point, the pump 200 stalls and will remain so until a demand for more pressurized air is received ( e.g. , when an amount of liquid is dispensed from one of the containers 44).
  • the beverage dispensing system 10 of the first embodiment can be used to dispense carbonated and non-carbonated drinks without the need for an external water source or electricity. Accordingly, the system is self-contained and, therefore, well-suited for portable beverage dispensing applications.
  • Figure 12 is a schematic view of a second embodiment of a self-contained pneumatic beverage dispensing system 300. Since the second embodiment is substantially similar in structure and function to the system 10 of the first embodiment except as to the source of water and the pressure levels provided to the various components, the following discussion of the second embodiment of the invention is focused on the water source 302 and these pressure levels.
  • the high pressure water tank 52 of the first embodiment is replaced with a low pressure water tank 304 and a high pressure water pump system 306 that includes a pneumatic water pump 308.
  • the low pressure water tank 304 has first and second chambers 310 and 312 that are separated by a pliable diaphragm 314. Since a high pressure pump 308 is included in the system, the water within the water tank 304 need not be at high pressure. Accordingly, instead of being supplied with CO 2 gas at approximately between 195 psi to 200 psi, the water tank 304 is supplied with gas at pressures approximately between 25 psi to 60 psi.
  • the low pressure water tank 304 can be constructed of mild steel as opposed to stainless steel which tends to be substantially more expensive.
  • pressurized water can leave the first chamber 310 of the tank through a water supply line 60.
  • the pressurized water supplied by the water tank 304 flows to the pneumatic water pump 308 to fill the pump with water.
  • the water flows through flat water line 74 to the cold plate 48.
  • the high pressure gas supplied by supply line 50 is directed to a pneumatic water pump control valve 316.
  • the control valve 316 is connected to a pump gas supply line 318, and to first and second pneumatic signal lines 320 and 322.
  • the pump gas supply line 318 connects in fluid communication to the pneumatic water pump 308 at its first end 324.
  • the pneumatic signal lines 320, 322 connect to first and second piston sensors 136 and 328, respectively.
  • the first piston sensor 326 is mounted to the pump 308 adjacent its first end 324 and the second piston sensor 328 is mounted to the pump adjacent its second end 330.
  • Each of the piston sensors 326, 328 is connected to a sensor gas supply line 332 which is in fluid communication with the supply line 50
  • the pneumatic water pump 308 comprises a piston cylinder 334 and a rodless piston head 336.
  • the rodless piston head 336 comprises a central magnet 338 that is positioned intermediate two piston end walls 340 and 342.
  • seals 344 and 346 Located between the magnet 338 and each of the end walls 340, 342 are seals 344 and 346.
  • these seals 344, 346 comprise an inner resilient O-ring 348 and an outer lip seal 350. Configured in this manner, the seals 344, 346 prevent fluids from passing between the piston head 336 and the piston cylinder 334, but permit sliding of the piston head along the cylinder.
  • piston sensor 326 senses the proximity of the piston head due to the magnetic attraction therebetween. When such a condition is sensed, the sensor 326 is activated and sends a pneumatic pressure signal to the control valve 316, causing the control valve to open. While in the open position, high pressure gas flows through the control valve 316, along the pump gas supply line 318, and into the gas side of the pump 308. The high pressure gas ejects the water contained on the water side of the piston head 336, eventually pressurizing the water to approximately between 195 psi to 200 psi.
  • the pressurized water flows to the carbonator tank 16 similarly as in the first embodiment.
  • the second piston sensor 328 activates in similar manner to the first piston sensor 326, and sends a pneumatic pressure signal to the control valve 316 that causes the valve to cut-off the supply of gas to the pump 308 and vent the pump cylinder 334 so that the relatively low pressure water can again fill the pump.
  • the first piston sensor 326 is again activated, and the system cycles again.
  • the system 302 can further include a pump reset switch 352 and/or an accumulator tank 354.
  • the reset switch 352 receives high pressure water from the pump 308 through water supply line 356.
  • the reset switch also receives low pressure CO 2 gas from the supply line 42 through gas supply line 358.
  • Linking the reset switch 352 and the pump control valve 316 is a pneumatic signal line 360 which connects to line 322. So arranged, the pump reset switch ensures that there is adequate amount of carbonated water to meet demand.
  • the reset switch 162 sends a pneumatic pressure signal to the control valve 316, causing the valve to close and vent the gas pressure in the pump so that the pump can be refilled and a full piston stroke then executed.
  • the accumulator tank 354 contains an internal diaphragm (not shown) which separates a first chamber of the tank a second chamber of the tank. In the first chamber is a volume of nitrogen gas. In operation, the second chamber fills with high pressure water supplied by the pump 308. As the accumulator tank 354 is filled, the nitrogen gas contained in the first chamber is compressed. In this compressed state, the gas can force the water out of the accumulator tank 354 during situations in which carbonated water demand is high and the pump 308 is in the refill portion of its cycle.
  • FIG 14 illustrates a first alternative carbonator tank and filling system 362 for use in either of the above described dispensing system embodiments.
  • the system 362 comprises a conventional electrically sensed, high pressure carbonator tank 364 and an electric power source 366.
  • the power source 366 typically comprises a battery.
  • Electrically connected to the carbonator sensor (not shown) are both the power source 366 and a low voltage pneumatic interface valve 368.
  • the interface valve 368 is in fluid communication with both a source of pressurized CO 2 gas and a pneumatic water valve 370.
  • the sensors When the electric sensors within the carbonator tank 364 detect that the carbonator tank is not full, the sensors electrically signal the interface valve 368. This signal causes the valve 368 to open and thereby send a pneumatic pressure signal to the pneumatic water valve 370 to cause it to open so that the carbonator tank 364 can be refilled in the manner discussed above.
  • FIG. 15 illustrates a second alternative carbonator tank and filling system 372 for use with either the beverage dispensing system which comprises a conventional high pressure carbonator tank 374.
  • the carbonator tank 374 is mounted to a vertical surface with a spring loaded carbonator mounting bracket 376. Coupled to this mounting bracket 376 is a pneumatic three-way valve 378 that is in fluid communication with a high pressure CO 2 gas supply line 380 and a pneumatic signal line 382 which, in turn, connected to a pneumatic water valve 384.
  • the carbonator tank 374 When the carbonator tank 374 is empty, it is supported by the carbonator mounting bracket 376 in an upright orientation. While in this upright orientation, the pneumatic three-way valve 378 is open, thereby sending a pneumatic pressure signal to the water valve 384 to remain open. Once the tank 374 is nearly full, however, its weight overcomes the strength of the spring within the bracket 376, causing the tank to tilt. This tilting action closes the three-way valve 378, which, in turn, closes the water valve 384 and shuts-off the supply of pressurized water to the carbonator tank 374.
