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.

A cartridge loader includes a lever arm, a hinge axle and a cam centered on the hinge axle, and a housing for receiving a cartridge, the housing having a first end and a second end, the first end adapted to connect to an appliance, and the second end adapted to allow the lever arm to open and close, the housing having an aperture exposing an interior of the housing, the aperture shaped to receive the cartridge and the lever arm, wherein the cam is adapted to assist in seating the cartridge in the housing when the lever arm is closed, and ejecting the cartridge when the lever arm is opened.

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.

A gas magazine for a pneumatic weapon simulator. A gas magazine fill station for a pneumatic weapon simulator. A method of filling a gas magazine for a pneumatic weapon simulator. The apparatus for filling and refilling a fluid reservoir of a magazine for a pneumatic firearm simulator from a source of pressurized fluid of the present disclosure includes: a receiver for receiving the magazine; a passage for conveying the pressurized fluid from the source of pressurized fluid to the fluid reservoir of the magazine received in the receiver; and, a vent valve in fluid communication with the passage for venting the pressurized fluid from the passage. The apparatus may further include a vent channel in fluid communication with the vent valve. The apparatus may also include a valve in fluid communication with the passage which is adapted for permitting pressurized fluid to be conveyed through the passage; and alternately, prevent pressurized fluid from being conveyed through the passage.

The invention relates to a pressure vessel (1), comprising a vessel body (3), wherein at an upper end of the vessel body (3) an end region (2) is formed in one piece with the vessel body (3), which has an opening (O), and a fastening structure (9) for a valve (6) formed on the inside of a wall (2.1) surrounding the opening (O) of the end region (2). According to the invention, two outflow openings (SO) are formed opposite each other in the wall (2.1) surrounding the opening (O) of the end region (2).

The invention relates to a pressure container (2) provided for multiple filling with a medium for introduction into a beverage, wherein an outer side of the pressure container (2) is formed with a marking (F1, F2, F3) associated with the medium. Furthermore, the invention relates to an assortment of pressure containers (1).

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

The present invention relates to a valve assembly configured to be arranged in a cylinder opening of a gas cylinder, comprising a valve housing having a first housing end and a second housing end, a first housing opening arranged at the first housing end and a second housing opening arranged at the second housing end, the first housing opening having an inner diameter, and a bore extending between the first housing opening and the second housing opening, the bore having an inner face, and an inner valve unit arranged in the bore, said inner valve unit having an inner valve housing, and a first end and a second end, the first end having an outer diameter, the outer diameter being larger than the inner diameter of the first housing opening, the first end being configured to abut the inner face at the first opening, whereby a filling valve is provided, the inner face of the first opening being a filling valve seat, the second end comprising an inlet to the inner valve unit, the inner valve unit further comprising a consumption valve arranged at the first end, and a first pressure reduction valve configured to reduce a pressure in the gas cylinder from a first gas pressure to a second gas pressure, wherein the valve assembly further comprises a protection device arranged in connection with and configured to interact with the inner valve unit to hinder unintended gas flow into the gas cylinder. The present invention also relates to a gas cylinder having a gas with a pressure and an opening, to a gas delivering system, to a gas consuming system and to a beverage dispensing system.
