An acronautical gas storage cryogenic tank device, comprising an inner container (26) defining a liquefied gas storage chamber (28), an outer envelope (27) containing the inner container (26) and made of a plurality of demountable parts for accessing the inner container (26), the outer envelope (27) being made of a material resistant to temperatures from less than 60 C. to at least +80 C. an insulation chamber (29) defined between the inner container (26) and the outer envelope (27), the reduced-pressure insulation chamber (29) having helium-tightness equal to or better than 10*9) millibar*litre/second defined between the inner container (26) and the outer envelope (27), two connections of which at least one is a sliding connection, supporting the inner container (26) and borne by the outer envelope (27), a removable collector (42) passing through the outer envelope (27) and the inner container (26) in a sealed manner, and a flexible thermally insulating neck (42) forming a sealed interface between the collector on the one hand and, on the other hand, the outer envelope (27) and the inner container (26), the neck (42) being formed around a portion of the collector (38), the neck (42) passing through the insulation chamber (29) in order to allow the collector (38) to be demounted independently of the pressure in the insulation chamber (29).

A multifunction valve for a tank containing high-pressure hydrogen of an automotive fuel cell system is provided. The multifunction valve has a thermal safety device, an auxiliary device adapted to act mechanically on a bulb of the thermal safety device to break the bulb, and a trigger group provided with a heat sensitive element consisting at least in part of a wire made of a shape-memory material.

An initiator for opening a pressurized gas cylinder is disclosed herein. The initiator includes a housing having a first end and a second end, a lance disposed within the housing, the lance configured to slide from the first end of the housing to the second end of the housing and out through the second end of the housing, a spring disposed within the housing between the first end of the housing and the lance, and a wire coupled to the first end of the housing and to the lance, the wire configured to hold the spring in a compressed state, the wire further configured to break in response to an electric current.

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.

The invention relates to a valve for pressurized fluid, the valve having a body incorporating a fluid circuit having an upstream end and a downstream end, the circuit having a seal valve, the seal valve enabling the circuit to be opened or closed, the valve having a member for controlling the seal valve, the seal valve being slidably mounted in the body so as to slide between a position in which the circuit is closed when the control member is in a rest position and a position in which the circuit is open when the control member is in an active position, the valve having a deformable member positioned between the seal valve and the control member. The invention also relates to a container or a set of containers for pressurized fluid comprising such a valve.

A connection space for a hydrogen supply arrangement, having an inner region surrounded by the connection space for receiving components of the hydrogen supply arrangement, an inert gas supply device for flushing the inner region with an inert gas, and an exhaust gas system for discharging the inert gas from the inner region, wherein the inert gas supply device is designed to continuously supply the inert gas to the connection space and/or to maintain a constant inert gas pressure in the connection space.

Embodiments of systems, methods, and canisters to filter flammable vapor and release filtered vapor during an overpressure event are disclosed. An embodiment of a method may include flowing a fluid from a sample vessel to a pressure relief device. The fluid may include one or more liquids and one or more flammable gases. The method may include flowing the fluid from the pressure relief device to a pressure flow reducer cylinder when the overpressure event occurs, reducing the pressure flow of the fluid in the pressure flow reducer cylinder, and flowing the reduced pressure flow fluid from the pressure flow reducer cylinder to a canister. The method also may include adsorbing vapors of the one or more flammable gases of the fluid when present in the reduced pressure flow fluid in the canister, thereby to obtain filtered vapor, and releasing the filtered vapor from the canister.
