Rapid comestible fluid dispensing apparatus and method

摘要

A nozzle assembly is disclosed which is capable of controlling pressure of comestible fluid exiting the nozzle assembly. To provide comestible fluid at rack pressure to the nozzle of the nozzle assembly, the nozzle can be provided with a valve movable through a number of closed positions to change pressure within the nozzle. Prior to fluid dispense, pressure at the nozzle is preferably reduced by increasing a volume within the nozzle assembly, such as by actuating the valve through its range of closed positions.
