ABSTRACT:
Shut-off valves each in place on a gas cylinder include a spring biased tubular spool also responsive to cylinder pressure. The valves direct a high pressure gas flow from their cylinder to a switching valve. The switching valve has a spring biased spool with axial passageways which serve to communicate one of a pair of inlet ports with an outlet port of the valve to provide a pressurized flow to a carbonator type outlet. Venting of the switching valve, to permit spool shifting, is done remotely by the shut-off valve associated with a partially used cylinder. An indicator gauge on the switching valve identifies which cylinder is in use.
