The invention relates to a device for providing pressurized fluid. The device includes a first functional assembly including a pressurized fluid bottle having an opening having attached therein a first tap including an inner fluid circuit including an insulating valve. The device includes a second functional assembly forming a physical entity separate from the first assembly. The second assembly includes a second tap having an inner fluid circuit. The first tap and the second tap include respective coupling members forming a removable rapid connection system. The device includes in the first assembly at least one electronic data storage communication unit that is removably, wirelessly queryable via electromagnetic waves and in that the second assembly includes at least one electronic communication unit for removably, wirelessly reading, via electromagnetic waves, data from the electronic member of the first assembly.

Pressurized gas bottles with integrated valves, in which a plurality of functional supports are integrated in an extraction unit, are equipped with complex fall protection means. Moreover, in such a valve, a new approval procedure is carried out for the entire valve in the event of multiple modifications, for example when supplementing it with an additional function. In order to reduce the effort associated with this, an extraction fitting for a pressurized gas bottle is provided with a modular design, wherein a base module comprising the shut-off member and a fall protection device securing the shut-off member complies with legal requirements regarding fall protection and the shut-off device of the pressurized gas bottle. All further functionalities of the extraction fitting are integrated in at least one additional module, which is connected to the base module in a fixed but removable manner and without impairing the fall safety.

According to some embodiments, an adjustable valve grip is presented. In an embodiment, the adjustable valve grip comprises a first portion and a second portion wherein the second portion is operatively connected to the first portion and wherein the first portion is dimensioned such a way that the first portion is capable of being snap-fit over a gas cylinder valve handle and wherein the second portion is dimensioned in such a way as to be capable of being adjusted through its operative connection to the first portion so that when the first portion has been snap fit over a gas cylinder valve handle a user can adjust the second portion to bring the second portion into firm contact with the gas cylinder valve handle, and wherein at least one of the first portion, or the second portion, or both are colored in such a way as to be easily visible to the human eye.

A method for calculating the autonomy of a gas distribution system assembly including a container containing gas and equipped with at least one gas filling indicator device and a gas flow rate indicator device at the output of the container. The method includes recovering at least one item of identification information on the container and/or the gas used. The method also includes acquiring at least one image to recover a first datum on a value indicated by the gas filling indicator device and a second datum on a value indicated by the flow rate indicator device. The method also includes communicating the at least one acquired image and the at least one recovered item of identification to a computation module configured to deduce therefrom a corresponding value of autonomy of the gas distribution assembly, the computation module including at least the ability to process images.

Protective devices for pressurized gas cylinders have a housing which is arranged around an inner cavity intended for receiving an extraction valve and which has access openings for the extraction connection and for further fittings. In order to counteract soiling or contamination of the extraction connection, the invention provides for an elastically deformable safety element to be fastened to the housing in the region of the access opening of the extraction connection, said element being able to be swung out from a closed position, in which the extraction connection is completely covered and/or enclosed by the safety element, into a position in which it frees the extraction connection.

The invention relates to a protective cap for a pressurized fluid cylinder valve, comprising a hoop defining a sheltered protected space, the lower end of the hoop being secured to the generally annular base that is intended to be mounted around the neck of a pressurized fluid cylinder. The cap is characterized in that the hoop comprises a draw-formed metal sheet. The invention also relates to the corresponding method.

A cap for closing a canister includes a receptacle including a bottom wall, and one or more walls extending upward from the bottom wall and defining an opening of the receptacle that is configured to receive a body of the canister, and a handle extending upward from the receptacle and defining vertical slots that are configured to receive respective hooks of the canister.

A pressure vessel transport system can have one or more handles that allow a pressure vessel to be efficiently and safely transported. The transport system can consist of a housing surrounding a pressure vessel with the pressure vessel having a valve. The housing may continuously extend along a longitudinal axis of the pressure vessel to position the valve within the housing.

A cryogenic liquid switching system including an electronic control mechanism; a solenoid valve communicatively connected to the electronic control mechanism via an interface cable; a gas input control connected to the solenoid valve; and a pair of pneumatic valve actuators connected to the gas input control via separate isolation tubing components The system also including a pair of valve actuator pins, one each connected to a respective one of the pair of pneumatic valve actuators; a pair of pneumatic valves, one each connected to a respective one of the pair of valve actuator pins; and a cryogenic liquid input in fluid communication with at least a portion of each of the pair of pneumatic valves. The system further including a first cryogenic liquid output in fluid communication with a first of the pair of pneumatic valves; a second cryogenic liquid output in fluid communication with a second of the pair of pneumatic valves; and a temperature probe positioned adjacent to an exit of the cryogenic liquid input to measure the temperature of an incoming cryogenic liquid and send a signal to the electronic control mechanism to open and close the pneumatic valves based at least in part on the temperature of the incoming cryogenic liquid.

A fully removable chime or valve guard that can support the container on its top, side and bottom is provided. The removable chime or valve guard provides protection if the container is dropped on its side or top. The protection provided allows the containers to pass a drop test per 49 CFR section 178.603, so the containers can be certified per 49 CFR 178.504.
