Examples disclosed herein relate to conduits, devices, systems and methods, which may include a hollow element including an inner surface and an outer surface which allows for a passage of one or more of one or more fluid elements and one or more gaseous elements, a constraining element with one or more openings and one or more non-open elements, one or more blocking elements configured to stop the passage of the at least one of the one or more fluid elements and the one or more gaseous elements when the one or more blocking elements are in a first position relative to the one or more openings, and a movement device configured to move the one or more blocking elements to a second position relative to the one or more openings which allows for the passage of the one or more fluid elements and the one gaseous elements through the one or more openings in the constraining element.

A nozzle (10) and associated methods are provided in which a base fluid flows by a check valve (22) and is directed by a plurality of flow directors (42) into a diluent flow path. The check valve (22) closes the flow of base fluid when the base fluid is no longer demanded.

A system and method of using an O-ring retaining apparatus to maintain an O-ring in the same position relative to the position of the handle of a bar gun while permitting a valve stem in physical contact with the O-ring to slide past without the O-ring becoming dislodged.

Disclosed is a beverage dispense system comprising a beverage flow path along which beverage flows in use from a beverage supply to a dispense site and a coolant flow path along which coolant flows from a cooler. The system further comprises a connector at an upstream end of the beverage flow path configured for releasable connection to the beverage supply. The connector comprises a beverage passage along which a portion of the beverage flow path extends and a coolant passage along which a portion of the coolant flow path extends. The system further comprises a sensor comprising two spaced probes arranged so as to be in contact with beverage flowing through the beverage passage in use to measure a parameter of the beverage, and a flexible tube-in-tube conduit extending from the connector. The conduit comprises an inner beverage tube extending within an outer coolant tube. The beverage tube is connected to the beverage passage so as to define a portion of the beverage flow path and the coolant tube is connected to the coolant passage so as to define a portion of the coolant flow path.

Provided is a beer dispensing device not requiring cleaning by using a disposable flexible tube to form a beer passage, and also provided is a device capable of dispensing foam as well as beer, using a single flexible tube. A beverage dispensing device 1 using a combination of tubes 12 having an elastically portion that is elastically deformable as a passage of a beverage 20 comprises a mechanism 32 configured to set the bore of the flexible portion to a first state having a first cross-sectional area or a second state having a second cross-sectional area smaller than the first cross-sectional area, selectively, and when the bore of the flexible portion is set to the second state, foam is generated from the beverage flowing through the tube.

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 control system for controlling one or more tapping valves included in a beverage dispenser includes a telematic communication network with a cloud server and a gateway for selecting a tapping valve and connecting the telematics communication network to the selected tapping valve. The cloud server is configured to send a control signal to the gateway and the gateway is configured to verify which tapping valve the control signal is directed to and forward the control signal to the tapping valve. The control logic unit of each tapping valve is configured to receive the control signal and execute a command and/or modify one or more parameters of a set of parameters and/or add one or more further parameters to the set of parameters.

A system for sanitising a fluid pathway in a drinking water dispensing assembly may include: a supply of water to be delivered under pressure through the fluid pathway; and a sanitising solution to be dispensed into the fluid pathway via a flow restrictor. The flow restrictor is configured to regulate the flow rate of the solution delivered to the fluid pathway to facilitate mixing between the water and the solution to an effective sanitising concentration within the fluid pathway.

A beverage server able to accurately customize concentrations of a nonalcoholic beverage and alcoholic beverage. The beverage server 10 has beverage dispensing parts 14, 18 having at least one of first discharge nozzles 16b, 20b or a second discharge nozzle 16c among first discharge nozzles 16b, 20b, a second discharge nozzle 16c, and water discharge nozzle 16a and dispensing a beverage and a control device 82 making a first flow jet pump 58 and first flow regulator 60 operate together so as to enable control of a discharge rate of the first liquid supplied to the first discharge nozzles 16b, 20b and making a second flow jet pump 74 and second flow regulator 76 operate together so as to enable control of a discharge amount of the second liquid supplied to the second discharge nozzle 16c, the beverage server able to adjust an alcohol concentration of the beverage dispensed from the first beverage dispensing part 14.
