ABSTRACT:
A motorless continuous carbonator including a double acting piston type water pump driven by a double acting piston type gas pump actuator assembly powered by the carbonating gas. A connecting rod couples the pump piston with the actuator piston and includes means for operating a toggle switch mechanism for controlling a pair of solenoid valves respectively connected to the pump and actuator assembly for controlling the flow of water and carbonating gas, typically CO.sup.2, therefrom and thus deliver still water and CO.sup.2 to a semi-permeable membrane carbonator. The CO.sup.2 gas which initially provides the pumping force is subsequently fed to the carbonator where it is absorbed by the still water to form carbonated water which is then fed to a dispensing unit which may be either a post-mix dispenser utilized either on earth or in a microgravity environment.
