Examples disclosed herein relate to conduits, devices, systems and methods, which may include a dispensing device including a valve configured to interact with an inlet stream, the inlet stream having a first pressure, the valve having an outlet area with an outlet stream, the outlet stream having a second pressure; and a solenoid configured to interact with the outlet stream.

A beverage dispenser includes a gas infusion device configured to infuse a gas into a base liquid to form a gas-infused liquid, a mixing chamber configured to mix the gas-infused liquid and a concentrate to thereby form a reconstituted beverage, a first flow control configured to decrease pressure of the gas-infused liquid prior to mixing with the concentrate, and a second flow control configured to decrease pressure of the concentrate prior to mixing with the gas-infused liquid. A restrictor device downstream from the mixing chamber and configured to apply backpressure on the concentrate and the gas-infused liquid, and a dispensing valve is configured to dispense the reconstituted beverage.

A method prepares and dispenses a beverage with a dispensing device. The device includes a housing with a beverage unit having a liquid line, a pressure controller to control liquid line pressure, and an ingredient container receiving means. The content of the ingredient container is in fluid communication with a liquid line to mix the ingredient container contents with a base liquid in the liquid line. The device further includes an ingredient container identification unit and a processor coupled for controlling the pressure controller. The method includes providing an ingredient container in the device, identifying the ingredient container, providing a base liquid, and mixing the contents of the ingredient container with the base liquid dispensing the prepared beverage. The pressure in the liquid line changes from a first pressure level to a second pressure level by the pressure controller during mixing and dispensing of the beverage.

The present invention provides a beverage preservation keg with an adjustable beer tap, including a shell, an inner container, and a gas-liquid control device; the inner container includes an upper gas storage chamber and a lower beer storage chamber; the gas-liquid control device includes a keg spear, a dispenser and a beer discharge pipe; the keg spear matches and communicates with the gas storage chamber and the beer storage chamber, and the top end of the keg spear matches and is connected to the dispenser; the dispenser is connected to the matching beer discharge pipe. The present invention has the function of adjusting the beer flow rate, and the keg spear is provided with a pressure relief valve, which eliminates the need for a gas tube and a separate pressure relief valve to connect the keg spear to the gas storage chamber in series.

A system comprising, a pressurized container including hollow portion and outer portion, pressurized container maintains pressure level in the hollow portion, transport system including two conduits, one transport being coupled to an interface and a valve port, the interface coupled to the hollow portion, the interface maintains pressure level in the hollow portion, one valve port allows flow of liquid volume through one conduit to a dispensing interface via another valve port, an external container is airtight and operable to dispense another liquid volume stored within, another conduit is coupled to the external container and further valve port to refill the liquid volume via the valve, pressure regulation system connected to pressurized container, pressure regulation system including a pressure conduit extending from outer portion through a pressure interface, pressure regulation system operable to compress liquid volume in the environment and a control system controls the valve and pressure regulation system.

A cartridge valve (22, 94) and system (10) are provided in which the cartridge valve (22, 94) includes a regulator (44, 96) a flow ring (67), and a solenoid (42, 100) which may have an adjustable stroke to facilitate stable flow control. Also, the cartridge valve (22, 94) includes a quick and easy installation and removal fitting (30 and 32).

Methods and devices for dispensing a cooled beverage are provided. One embodiment of methods includes the steps of mixing a diluent and a concentrate to make a diluted solution. The diluted solution is carbonated to yield a carbonated solution. The carbonated solution is cooled to below 0? C. to produce the cooled beverage, and the cooled beverage is dispensed through a nozzle. A device for dispensing a cooled beverage, where the cooled beverage comprises a diluent having a freezing point at STP includes an upstream cooler that pre-cools a supply of diluent to a temperature above the freezing point. A mixer mixes the pre-cooled diluent with a concentrate to make a diluted solution. A downstream cooler further cools the diluted solution to below the freezing point. A dispenser dispenses the downstream-cooled solution to atmosphere. The temperature of the cooled beverage is below the freezing point when dispensed.

Disclosed is a water dispenser. The water dispenser includes a water outlet component; a water cooling module for accessing a water source, an output port of the water cooling module being communicated with the water outlet component through a first water pump; and/or a water heating module, an input port of the water heating module accessing the water source through a second water pump, an output port of the water heating module being communicated with the water outlet component, the water outlet component accessing the water source through the second water pump.

A fixed nozzle pump appropriate for food service and dispensing of other fluids of varying viscosities is contemplated. The components are modularly connectable for easy assembly and cleaning. A piston and sealing ring cooperate with the chamber extension formed in the pump body to facilitate reciprocating pump action while minimizing the number of components disposed in and exposed to the fluid flow path. A novel, injection-moldable valve is integrated on the dispensing nozzle. The entire assembly may be disposed within a container shell which itself includes a replaceable pouch filled with the fluid to be dispensed.

Examples disclosed herein relate to conduits, devices, systems and methods, which may include a dispensing device including a valve configured to interact with an inlet stream, the inlet stream having a first pressure, the valve having an outlet area with an outlet stream, the outlet stream having a second pressure; and a solenoid configured to interact with the outlet stream.
