A fluid dispenser can include a body defining a passageway from an inlet to an outlet, a fluid container configured be received by the body such that the fluid in fluid communication with the inlet, and a contactless valve in fluid communication with the outlet and configured to selectively dispense fluid from the fluid container. A contactless valve configured to dispense a liquid can include an actuator configured to move a plug between a closed position in which the plug prevents the flow of liquid through valve body, and an open position in which liquid can be dispensed through an outlet. The valve can include an activation sensor, a presence sensor, and a controller configured to control the actuator and in electrical communication with the activation sensor and the presence sensor.

A touchless beverage dispensing valve assembly includes a nozzle and a valve configured to control a flow of a substance through the valve to the nozzle. A solenoid is configured to operate the valve between open and closed conditions. A trigger sensor includes an optical sensor and a controller. The controller executes a trigger sensor control module to receive an output from the optical sensor and operate the solenoid to control the valve between the open condition and the closed condition. A feedback device is operable to selectively provide a visual indication an operational status of the valve.

Exemplary embodiments include a filling apparatus that can be connected to a valve on a keg, such as a Sankey-D valve, and can be used to pour alcohol and other liquids into the keg, which may be pre-filled with a non-alcoholic drink mix. The filling apparatus has an upper structure coupled to a valve assembly which is coupled to a lower structure configured to mate with a keg valve. The filling apparatus may be designed to depress portions of the keg valve to allow for both filling and venting of the keg simultaneously. The filling apparatus may include a Sankey-D coupler or a coupler with a probe portion as the lower body portion.

A filling apparatus includes an upper hollow body having a top opening and a bottom opening; a first annular cylinder coupled to the upper hollow body via the bottom opening; a locking ring having a first keg lock slot and a second keg lock slot and coupled to the first annular cylinder; a second annular cylinder coupled to the first annular cylinder; a body seal ring coupled to the second circular cylinder; a bottom hollow cylinder coupled to the second annular cylinder and including a first vent opening probe, a second vent opening probe, and a probe divide wall. The filling apparatus can be connected to a valve on a keg, such as a Sankay-D valve, and can be used to pour alcohol and other liquids into the keg.

A cock (10) that receives and discharges the carbonated water from a nozzle (70) includes: a first flow path (4S); and a second flow path (46). A flow path transverse Closs-section has an annular shape. The second flow path has an outer diameter larger than that of the first flow path and having a flow path cross-sectional area smaller than that of the first flow path; and a shaft (50) which forms the inner circumferential surface of the second flow path. the shaft having a ring-shaped groove (52) formed over the outer circumference of the shaft in a part of the second flow path that is connected to the first flow path, wherein a longitudinal center axis line (C1) of the first flow path is nonparallel to and does not intersect with a longitudinal center axis line (C2) of the second flow path.

A liquid dispenser, such as a water purifier, in one embodiment includes a water discharger connector provided with a water discharge valve configured to control discharge of purified water and a water discharge pipe connected to the water discharge valve, and a water discharger coupled to an upper side of the water discharger connector, and provided with a connector part that connects to the water discharge pipe based on fitted-coupling.

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.

There are provided a liquid supply system and a liquid loss reduction method capable of reducing a liquid loss caused when a liquid storage container is replaced. A liquid supply system (101) that transfers a liquid in a storage container (10) through a supply pipe (30), and dispenses the liquid from a dispensing outlet in a dispensing device (50). The liquid supply system includes a spout prevention unit (110) that is installed in the supply pipe, has a predetermined internal volume, and prevents a pressurized gas from being spouted from the dispensing outlet, a liquid-absence detection device (120) that is installed between the storage container and the spout prevention unit, and detects absence of the liquid in the storage container, and a control device (130) that is electrically connected to the liquid-absence detection device, and gives instructions for closing a flow path in the dispensing device in response to the detection of the absence of the liquid in the storage container.

Cartridge loaders for fluid mixture dispensing systems are disclosed. One disclosed fluid mixture dispensing system comprises an interface surface, a cartridge receiver carriage, and an actuator configured to depress the cartridge receiver carriage towards the interface surface to load a cartridge. The fluid mixture dispensing system is configured to apply continuous downward pressure on the cartridge towards the interface surface when the cartridge is loaded and is in contact with the interface surface.
