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.
1. A comestible fluid dispensing apparatus, comprising:a nozzle having at least one wall; a valve received within the nozzle, the valve and the at least one wall defining a substantially fluid-tight chamber within the nozzle for receiving and retaining comestible fluid; and an actuator coupled to the valve for moving the valve in telescoping relationship with respect to the nozzle, the valve having at least one open position and a range of closed positions in which the valve is sealed at different locations in the nozzle corresponding to a range of comes...
