An improved carbonated LIQUID dispenser has a passageway between the carbonated LIQUID and an outlet valve. A foam inhibiting portion of the passageway progressively decreases, then increases, then decreases, and finally increases again in flow area. Preferably the flow inhibiting portion of the passage comprises a chamber containing two spherical bodies which are fixed in the chamber and which are unequal in diameter.
In a carbonated liquid dispenser having means for defining a flow path for the carbonated liquid from a container thereof to an outlet opening, a valve means for selectively opening and closing the outlet and a foam inhibiting means in the flow path upstream from said valve means for defining a passage portion of varying cross section over a finite distance within the path for retarding foaming of the carbonated liquid over said flow path, said flow inhibiting means including means for reducing the flow area along the path from a first relatively large a...
