Self-contained high pressure pneumatic beverage dispensing system

摘要

The present disclosure relates to a self-contained high pressure pneumatic beverage dispensing system. In each embodiment of the dispensing system, the dispensing system comprises a carbonator tank dispensing system which includes a water valve that is adapted to connect in fluid communication to a carbonator tank and to a source of pressurized water. The water valve has an open position in which water from the source of pressurized water can flow through the water valve and into the carbonator tank and further has a closed position in which water from the source of pressurized water cannot flow through the water valve into the carbonator tank. The dispensing system further includes at least one proximity switch that is adapted to operably connect in fluid communication to the water valve and a source of pressurized gas. The proximity switch has an open position in which gas from the source of pressurized gas can flow through the proximity switch and a closed position in which gas from the source of gas cannot flow through the proximity switch. In use, the proximity switch is configured so as to detect a fill condition of the carbonator tank so that the proximity switch can send a pneumatic signal to the water valve to cause the water valve to open or shut depending upon the detected fill condition.
