Abstract: The invention concerns a device for dispensing a beverage comprising a mixture of liquid, e.g. water, and at least one liquid concentrate, with at least two liquid nozzles connected respectively to at least one liquid source for producing a first jet of liquid in air along first path and a second jet of liquid in air along a second path, at least one concentrate nozzle connected to at least one liquid concentrate source for delivering a stream of liquid concentrate in air along a third path, wherein the liquid nozzles and the concentrate nozzle are oriented with respect to each other so that the first, second and third paths intersect above a container at a common intersection point, whereby the mixture is formed by collision of the respective jets and the stream(s).

Abstract: A dispensing device comprising pump for dispensing liquid, the pump comprising a hollow piston moveable within a cylinder, and a valve, controlling the supply of liquid to the piston/cylinder. During a first phase of operation the piston moves outwardly within the cylinder while the valve permits the supply of liquid into the chamber and during a second, subsequent, phase of operation the piston moves inwardly within the cylinder while the valve shuts off the supply of flowable material, with the result that liquid drawn into the chamber during the first phase is pressurized. Arrangements for effective priming and pre-compression of liquid are also described.

Abstract: Disclosed herein is a coupler, which is used for discharging a chemical outside a container and includes an internal coupler unit and an external coupler unit. The internal coupler unit includes a mounting part and a coupling pipe. The external coupler unit includes a main housing. Coupling seats are formed in respective opposite ends of the main housing, and a side hole is formed in the main housing. The external coupler unit further includes a hollow rod member, and a hollow cylindrical member. The external coupler unit further includes a subsidiary housing fitted over the hollow cylindrical member, a fluid opening control unit, a pumping means connector, a gas injection means connector tightened into the side hole of the main housing, and sealing caps, which close respective openings of the pumping means connector and the gas injection means connector when not in use.

Abstract: A drink dispenser which is particularly suitable for use on board a passenger plane, comprises a drink preparation unit and a supply unit. The supply unit has a fuel cell system with a fuel cell and is configured to supply the drink preparation unit with water, electric energy, and thermal energy produced by the fuel cell.
