Abstract
A carbonator comprising a casing defining an elongate chamber having a helically grooved inner wall and an elongate inner body disposed in the chamber and having a cylindrical outer surface contacting radially inner crests on the helically grooved inner wall to form a helical flow passage therewith. Liquid to be carbonated is supplied to the helical flow passage adjacent one end thereof and an outlet communicates with said helical flow passage adjacent a second end. The inner body has an inner gas chamber extending only along a portion of the length of the helical flow passage, which portion is formed of micro-porous material for diffusing carbon dioxide gas from the inner chamber into the liquid in the helical flow passage.
