Abstract
Abstract An adjustable carbonated liquid dispensing nozzle is provided which maintains a high percentage of dissolved carbon dioxide in the liquid being dispensed. The dispensing nozzle is coupled to a control valve which controls the flow of carbonated liquid to the dispensing nozzle. The control valve may also selectively control the flow of one or more other fluids to the dispensing nozzle for mixture with the carbonated liquid. The dispensing nozzle includes an adjustable diffuser having a plurality of members in spaced relation to define flow paths therebetween. Means for maintaining a constant flow rate of carbonated liquid are located upstream of the diffuser. The diffuser is adjustable to provide a variable amount of dissolved carbon dioxide in the dispensed liquid while maintaining a substantially constant flow of liquid. The diffuser includes at least two relatively movable members which define a carbonization control gap therebetween and further includes a gradually increasing transverse area flow path for gradually exposing the carbonated liquid to atmospheric pressure. The carbonization control gap and the flow path cooperate to regulate the percentage of dissolved carbon dioxide in the dispensed liquid.
