Preferred embodiments of the invention have a nozzle assembly capable of controlling pressure of comestible fluid exiting the nozzle assembly, a refrigeration system in which refrigerant pressure and temperature is controllable to enable comestible fluid temperature control, heat exchangers cooling comestible fluid in the nozzles, an ultraviolet sterilization system for sterilizing interior and exterior system locations, and a hand held comestible fluid dispenser capable of cooling and selectively dispensing one of several comestible fluids. Fluid pressure and velocity can be reduced for improved dispensing by a valve movable through a number of closed positions and/or by a diffuser in the nozzle. A purging and priming valve assembly with or without associated sensors can be employed for manual or automatic system purging and priming and for fluid temperature control.

Comestible fluid dispensing apparatus and method

Preferred embodiments of the invention have a nozzle assembly capable of controlling pressure of comestible fluid exiting the nozzle assembly, a refrigeration system in which refrigerant pressure and temperature is controllable to enable comestible fluid temperature control, heat exchangers cooling comestible fluid in the nozzles, an ultraviolet sterilization system for sterilizing interior and exterior system locations, and a hand held comestible fluid dispenser capable of cooling and selectively dispensing one of several comestible fluids. Fluid pressure and velocity can be reduced for improved dispensing by a valve movable through a number of closed positions prior to opening and/or by a diffuser in the nozzle having an increasing cross sectional area upstream of a nozzle portion having a relatively constant cross sectional area. A purging and priming valve assembly with or without associated sensors can be employed for manual or automatic system purging and priming and for fluid temperature control.
