A beverage dispensing system, has: a reservoir; a line connected to the reservoir; a tap connected to the line; a first valve connected to the line downstream of the reservoir, the first valve having a first open configuration and a first closed configuration; and a second valve connected to the line, the second valve having a second open configuration and a second closed configuration, the second valve being in the second closed configuration when the first valve is in the first closed configuration, when in the second closed configuration, the second valve blocking fluid communication between the tap outlet and the first valve, the second valve being in the second open configuration when the first valve is in the first open configuration to connect the reservoir to the tap outlet through the first valve and the second valve.

A valve closure for dispensing liquid by means of a pressurised gas has an inner sleeve (12) which includes a socket (16) and an annular inner valve seat (18). The inner sleeve carries a ring seal (14) which is urged against an outer valve seat (9) by an outer spring (15). A valve member (21) has an annular sealing face (23) co-operable with the inner valve seat (18) and a spring (24) urges the valve member (21) against the inner valve seat (18). The valve member (21) incorporates a plurality of projections (26) spaced radially from the annular sealing face (23). The valve closure can be used with a dispensing coupler having a tubular probe with a circumferential ring seal and a locking recess to engage the locking fingers of a detachable closing element.

A water-dispensing device includes a water tank, a dispensing line, a pump configured to draw water from the tank into the dispensing line, an outlet line, a dispensing valve, a spigot downstream of the outlet line and in selective fluid communication therewith via the dispensing valve, and a valveless directional fitting that couples the dispensing line to the outlet line for enabling fluid communication therebetween. The fitting has a hollow main body extending between an inlet port and a dispensing port. The dispensing line is connected to the inlet port and the outlet line is connected to the dispensing port. The fitting has a recirculation port that intersects an interior of the main body. The recirculation port has a smaller diameter than the dispensing port. A recirculation line is connected to the recirculation port and the water tank to place the water tank in fluid communication with the recirculation port.

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 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.

A cartridge and an associated beverage mixture dispensing system are disclosed. The cartridge is detachable from the associated beverage mixture dispensing system. The cartridge includes a casing and at least twenty ingredient reservoirs located within the casing and storing at least twenty respective ingredients. The cartridge also includes a dispensing interface for dispensing the at least twenty ingredients into the beverage mixture dispensing system. The at least twenty ingredient reservoirs include a first reservoir of a concentrated salt and a second reservoir of a concentrated food grade acid. The remaining ingredient reservoirs include additional concentrated ingredients. The beverage mixture dispensing system includes a solvent reservoir and a receiving interface for receiving the at least twenty ingredients from the cartridge. The beverage mixture dispensing system also includes a mixing area fluidly connected to the solvent reservoir and the at least twenty ingredient reservoirs.

An example system includes an incompressible, airtight pressurized container operable to maintain a pressure level in an internal pressurized environment, a transport system including at least two liquid transport conduits, and a mixing component, the two liquid conduits each being releasably coupled to a pressurized container interface coupled to the pressurized container and a dispensing interface, each liquid transport conduit including a controllable valve to enable or disable a flow of the liquid volume, the pressurized container interface capable of maintaining the pressure level, the mixing component being coupled to the at least two liquid transport conduits and the dispensing interface, a pressure regulation system connected to the pressurized container, the pressure regulation system operable to exert and maintain the pressure level within the pressurized container to enable compression of the first compressible liquid volume, and a control system operable to control the controllable valves and the pressure regulation system.

Systems and methods for sanitizing a fluid mixture dispensing system are disclosed. One system comprises at least one reservoir for storing a substance, a mixing area, and a controller. The controller is programmed to cause the system to execute a mixing cycle and a cleaning cycle. During the mixing cycle the substance is dispensed from the at least one reservoir to the mixing area to prepare an ingestible fluid mixture. During the cleaning cycle, the substance is dispensed from the at least one reservoir to the mixing area to sanitize the mixing area.

A fluid mixture dispensing system using a membrane to seal multiple reservoirs is disclosed. The multiple reservoirs each contain a respective ingredient. The reservoirs are coupled to respective orifices in a plate. The respective ingredients are dispensable via the respective orifices. The membrane seals the respective orifices. The ingredients are dispensed into one or more channels formed between the membrane and the plate. In specific embodiments, the membrane is an integral part of a cartridge which contains the multiple reservoirs. In specific embodiments, the cartridge includes an inlet and an outlet. A solvent flows from the inlet to the outlet through the one or more channels, and the ingredients are dispensed into the solvent in the one or more channels.
