A carbonation machine may include a carbonation head, a holder that is configured to hold a gas canister, the holder comprising a connector with a socket configured to enable linear insertion of a valve of the canister into the socket, the socket including a seal with at least one lateral opening to enable fluidic flow between one or more laterally oriented ports of the valve and a conduit of the holder while preventing leakage of gas from the fluidic flow, and a holding mechanism configured to hold a lateral projection from the canister after insertion of the valve into the socket such that the valve remains in the socket, and an activation mechanism configured to operate the valve to release the gas from the canister when inserted into the socket so as to enable the gas to flow via the conduit to the carbonation head.

An adapter for a canister filling system includes a body having an opening that is shaped to enable insertion of a valve of a gas canister for holding a pressurized or liquefied gas, into an interior space of the body, leaving a sealed gap between at least a portion of a lateral aspect of the valve and an internal surface of the body facing the interior space; and at least one channel that is configured to conduct pressurized or liquified gas from a canister filling system into the sealed gap in the interior space, so as to reach one or more lateral exterior ports of the valve of the gas canister that open laterally to a longitudinal axis of a body of the gas canister, when the valve is inserted in the interior space, to facilitate filling of the gas canister with the pressurized or liquified gas through said one or more lateral exterior ports of the gas canister.

The present disclosure provides systems and methods for refilling fluid containers. A fluid container may include a bottle and a valve assembly. The valve assembly may include two valves and be configured to engage with the bottle and a filling head or dispensing head. A system is configured to provide pressurized fluid to the refillable container, monitor filling, determine when to stop filling, and determine how much fluid was provided. The valve assembly may include a float mechanism coupled to one of the valves of the valve assembly to ensure fluid flow is stopped when the fluid container is full. The fluid, which can include carbon dioxide, is stored in a storage tank. A flow system provides the fluid to a filling head, which engages with the fluid container. The flow system includes a transfer pump, valves, and sensors configured to provide the fluid to the filling head.

In a connection device for coupling a gas pressure container provided with a connection coupling there is provided a guide device which is pivotable about a pivot axis between first and second pivoted positions, wherein the guide device includes an opening for inserting the gas pressure container in an insertion direction extending radially with respect to the pivot axis. A plug nipple is rigidly arranged on the connection device and projects into an inner region of the guide device such that the longitudinal axis of the nipple extends radially relative to the pivot axis and is situated parallel to the insertion direction in the first pivoted position of the guide device. The gas pressure container possesses a connection coupling with a rotationally symmetrical valve body having a coupling opening for receiving the plug nipple. The valve body is mounted within a coupling housing for rotation about an axis of rotation extending perpendicularly to the center axis of the coupling opening and has its outer circumferential surface sealingly mounted to an inner wall of the coupling housing. An outlet bore in the valve body communicates with the coupling opening and, in a second rotational position of the valve body, is in fluidic connection with the pressure container.

An air reservoir system is provided that includes a switchable valve to direct input air to an air reservoir, or stored air in the air reservoir to a firing pathway. Various example embodiments of the present general inventive concept may also include an air-saver system to maintain a minimum air pressure in the air reservoir during a firing operation.

A valve comprising a first chamber (111) and a second chamber (112), wherein a movable member (204) is arranged to selectably bring the first and second chambers into and out of fluid communication with one another, the movable member arranged such that when in an open position wherein the first and second chambers are in fluid communication, gas at a first pressure in the first chamber provides a closing force to a first surface area (222) of the movable member to overcome an opening force provided by gas at a second pressure in the second chamber on a second surface area (223) of the movable member whereby the movable member moves to a closed position to isolate the first and second chambers, and further arranged wherein as the movable member moves to the closed position, the second surface area of the movable member exposed within the second chamber is reduced thus reducing the opening force provided by the gas at the second pressure and providing a bias towards the closed position.

A gas source for pressuring sparkling and other beverage containers, e.g., to re-pressurize the container to keep a carbonation level of beverage during storage.
