A motorless carbonator including a double acting diaphragm type pneumatic water pump is connected between a carbonator tank and a water supply. The pump is driven by the carbon dioxide fed to the carbonator tank. Control of the pump is by way of an electrically operated shut-off valve which is opened and closed in response to a water level sensor in the carbonator tank. Coupled between the carbonator tank and the pneumatic pump is a spring biased diaphragm valve assembly which is normally biased closed, but is opened when the pump is actuated to feed wat...
A motorless carbonator comprising: a closed container for mixing water and gaseous carbon dioxide to form carbonated water which is then accumulated in said container; means for sensing the level of carbonated water in said container; means for feeding carbon dioxide from an external source into said container; a pneumatic water pump driven by carbon dioxide being fed to said container; a carbon dioxide input control valve coupling carbon dioxide to said water pump and being operable in response to said level sensing means to activate and deactivate said...
