An in-stock compressed fluid cartridge system to be used in a gas powered airsoft gun. The compressed fluid cartridge may be supplied fluid to a multi-stage expansion chamber configured to depressurize the fluid into gas and prevent fluid from reaching a downstream pressure regulator. The compressed fluid cartridge may be engaged and disengaged with the in-stock system by turning a thread-less quick release end cap that allows rapid replacement of the cartridges.

This invention relates to a novel method and system for dispensing CO2 vapor without over pressurization from a system having multiple containers. The system includes one or more liquid containers and one or more vapor containers. The system is designed to operate in a specific manner whereby a restricted amount of CO2 liquid is permitted into the vapor container through a restrictive pathway that is created and maintained by a shuttle valve during the filling operation so that equalization of container pressures is achieved, thereby allowing shuttle valve to reseat when filling has stopped. During use, a pressure differential device is designed to specifically isolate the vapor container from the liquid container so as to preferentially deplete liquid CO2 from the vapor container and avoid over pressurization of the system until the vapor container becomes liquid dry. The system can be operated so that at least 50% of the CO2 vapor product is dispensed from the vapor container.

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.

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 present invention relates to an aquarium pressurized gas vessel for supplying an aquarium (12) with CO2 gas generated in the aquarium pressurized gas vessel (10), the aquarium pressurized gas vessel (10) having a receiving vessel (14) for receiving a nutrient substrate and a reactant interacting with the nutrient substrate such that the nutrient substrate and the reactant react with each other to generate CO2 gas; a closing device (16) for closing the receiving vessel (14) in a pressure-tight manner; a gas outflow device (18) for extracting CO2 gas from the aquarium pressurized gas vessel (10) for the aquarium (12), the CO2 gas having a gassing pressure (p_B) when flowing into the gas outflow device (18); a gas vessel pressure regulator (20) for adjusting a gas vessel pressure (p_G) which substantially corresponds to the gassing pressure (p_B). Further, the present invention relates to a CO2 gassing system (28) which includes the aforementioned aquarium pressurized gas vessel (10).

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.

A valve for selectively closing and selectively opening a gas cartridge for a water carbonator, the valve is configured to hold a gas in the gas cartridge when the valve is closed and to provide a fluidic connection when the valve is opened, the valve has a valve housing having a cartridge connector opening that is oriented along a longitudinal axis of the valve, so that the gas is able to flow into the gas cartridge and flow out of the gas cartridge in a direction of the longitudinal axis, the valve housing has at least one outlet opening arranged externally and arranged along a direction parallel to the longitudinal axis so that the gas is able to flow from the valve in the direction parallel to the longitudinal axis, and the at least one outlet opening is arranged spaced apart from the longitudinal axis.

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. A gas cylinder can include a cap with a flange and catch below the flange. The catch can be engaged by a cylinder support to move the cylinder into contact with a piercing element to pierce the gas outlet of the cylinder and form a seal between the cylinder and gas receiver. A pressure indicator can have a single pressure sensor to indicate a capacity of a gas cylinder to deliver pressurized gas and a pressure in a beverage container.
