2034011 9100137 PCTABS00003 A motorless batch carbonator for a carbonated drink dispenser is located in a chilled water bath (18) including a set of evaporator coils (16) located on the outside of the water bath with the ice build up on the inside thereof being controlled by an ice bank detector (22). The carbonator is comprised of an immersible closed tank (30) including a semi-permeable membrane carbonating section (32) where still water and CO2 gas are mixed together. Still water from a pressurized source is fed into the interior of the carbonator tank which is pressurized to operate a spring-biased spool valve (42) for opening and closing a CO2 supply line (50). A vent passage (70) through the top of the carbonator chamber is opened and closed to atmospheric pressure in response to the manual actuation of a spring-biased dispensing plunger (64) which includes a fluid dispensing path (62). A constrained spherical float device (80) resides on the surface of the carbonated water inside of the tank and to open and close the vent passage and thus control tank pressurization and operation of the spool valve controlling the supply of CO2.
