Some embodiments of the present invention provide a comestible fluid dispensing apparatus including a nozzle defining an interior space and having a fluid inlet through which fluid is received within the interior space and a fluid outlet through which fluid exits the interior space and a substantially conical valve movable relative to the nozzle between different positions with respect to the nozzle and shaped to reduce turbulence and/or provide improved dispensing control.

Rapid comestible fluid dispensing apparatus and method

A lighter-than-air airship system, having a multitude of uses, with a primary purpose being the dispensing of water over a raging fire, where access by personnel and ground equipment is difficult. The airship system comprises an aerodynamically configured structure having a semi-rigid keel or skeleton, where lift is provided in part by helium, with the keel mounting a liquid management mechanism preferably consisting of a reservoir open to the outside for resupply of liquid or water, a conduit leading to a holding tank, and a piping distribution and nozzle assembly below the airship system to spray or dispense the liquid or water, like an artificial rain, over selected areas to control or extinguish the raging fire. Alternate systems are provided for replenishing or filling the holding tank from ground locations.

Liquid dispensing lighter-than-air airship system

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 present 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 control of comestible fluid temperature, heat exchangers connected to cool comestible fluid in the nozzles, an ultraviolet sterilization system for sterilizing locations outside and inside the system, and a hand held comestible fluid dispenser capable of cooling and selectively dispensing one of several comestible fluids supplied thereto. To provide comestible fluid at rack pressure to the nozzles in one highly preferred embodiment, each nozzle preferably has 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 actuating the valve through its range of closed positions. To improve temperature control and cooling efficiency, the present invention preferably employs heat exchangers adjacent to the nozzle assemblies. Due to their locations close to the nozzle assemblies, the heat exchangers generate convective recirculation through the nozzle assemblies to cool comestible fluid to the discharge openings thereof. The present invention can take the form of a multi-fluid dispensing gun having such a nozzle and heat exchanger relationship and having the pressure controlling valve as described above. To further improve control of comestible fluid temperature, the present invention preferably has an evaporator pressure regulator to control refrigerant pressure upstream of the refrigeration system compressor and a hot gas bypass valve to control refrigerant temperature.

Refrigeration apparatus and method for a fluid dispensing device

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.

Hand-held rapid dispensing apparatus and method

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.
