ABSTRACT:
The riser is used for the substantially foamfree drawing of gaseous liquids, preferably liquids containing carbon dioxide, or gasfree liquids from gas-pressurized receptacles. The riser is equipped with an entry chamber, a downstream reduction chamber connected to it and a reduction pin movable in both chambers. Preferably a calming chamber of widened cross-section is formed in rising direction behind the reduction chamber. The riser enables gasfree and gaseous liquids, in particular beverages containing carbon dioxide, to be drawn from receptacles independently of the gas pressure inside them, substantially without causing the liquid to foam. The riser, in connection with a receptacle closure fitting, may with ease be changed from one receptacle to another.
