Apparatus for gas distribution

A valve for pressurized fluid housing a fluid circuit having an upstream end and a downstream end and a valve for controlling the flow rate in the circuit that is controlled by a movable actuating member in order to control the opening or the closing, the valve having a lower end provided with movable coupling member(s) intended to cooperate with one or more complementary coupling members on a gas source or a circuit, the valve further comprising a member for locking the coupling member(s) that is mounted movably on the body of the valve between a first position not blocking the movement of the coupling member(s) and a second position blocking the movement of the coupling member(s).

Valve and device for supplying pressurized fluid

Device for supplying pressurized fluid, including a first valve accommodating an internal fluid circuit, the device having a second valve having an internal circuit, the second valve forming a separate physical entity from the first valve, the first valve and the second valve having respective coupling members that form a male/female quick-connection system for removably connecting the second valve to the first valve, the internal circuits including a set of control valves for allowing or preventing the flow of the fluid towards an outlet of the device when the second valve is coupled to the first valve via the quick-connection system.

Device for supplying pressurized fluid, and assembly for storing pressurized fluid, comprising such a device

Gas bottle cap

A valve for a pressurized fluid, including a body housing a fluid circuit including an upstream end configured to be placed in communication with a reserve of pressurized fluid and a downstream end configured to be placed in communication with a user apparatus, the circuit including a control valve controlling the flow rate in the circuit, the control valve being operated by a mobile actuating member to command the opening or the closing thereof, the valve including a first wireless remote communications electronic member using electromagnetic data waves, wherein the first electronic communication member is secured to a support component mounted to move on the body of the valve between at least a first position and a second position with respect to the body.

Pressurized fluid device and valve and method of identification

A cylinder of pressurized fluid, including a valve assembly housing a fluid circuit including at least one shut-off valve, the cylinder being equipped with a bonnet for protecting the valve assembly including a rigid structure delimiting a protective volume around the valve assembly, including a pressure indicating device including at least one piston sensitive to the pressure in the cylinder and mobile relative to the body of the valve assembly according to the level of pressure in the cylinder between at least a retracted first position and a deployed second position, the pressure indicating device including at least one mobile information support configured to collaborate mechanically with the piston, the information support being able to move between at least two distinct positions or states to symbolize respectively at least two levels of pressure according to the position of the piston.

Cylinder of pressurised fluid

A valve for a pressurized fluid, including a body housing a fluid circuit including an upstream end configured to be placed in communication with a reserve of pressurized fluid and a downstream end configured to be placed in communication with a receiver apparatus, the circuit including a control member controlling the flow rate in the circuit, said flow rate control member being operated by a mobile actuating member configured to move relative to the body of the valve, the valve including at least a first functional electronic member and a second functional electronic member, the second functional electronic member being mounted removably on the body of the valve.

Valve for pressurized fluid

A device for supplying pressurized fluid, including a first valve accommodating an internal fluid circuit, the device including a second valve including an internal circuit, the second valve forming a separate physical entity from the first valve, the first valve and the second valve including respective coupling members that form a male/female quick-connection system for removably connecting the second valve to the first valve, the internal circuits including a set of valves configured to allow or prevent the flow of the fluid towards an outlet of the device when the second valve is coupled to the first valve via the quick-connection system.

Device for supplying pressurized fluid, and assembly for storing pressurized fluid comprising such a device

Gas supply device, comprising a frame equipped with a base and accommodating a plurality of pressurised fluid cylinders connected to a fluidic circuit comprising a first connection end connected to the cylinders and a second end comprising at least one fluidic connection intended to be connected removably to an extraction or filling element for the cylinders, the frame comprising on one of its faces at least one opening giving access to at least one connection of the circuit, the frame also comprising at least one attachment element provided to cooperate with a lifting device.

Gas supply device

The invention relates to a container/container support assembly, notably for a medical gas cylinder, comprising a gas container () comprising a protective cap () comprising a peripheral wall (), and a container support () able and designed to accept and bear said gas container (). The protective cap () of the gas container () comprises a fixing element () projecting from the surface of the peripheral wall (), and said container support () comprises an attachment system () for fixing said container support () to a bearing structure (), and a housing () able and designed to accept said fixing element () borne by the protective cap () of the gas container () so as to secure said gas container () to said container support () when said fixing element () is positioned in said housing () of the container support ().

Assembly of a support and gas container such as a medical gas cylinder

The invention relates to a gas distribution assembly comprising a gas container (), such as a gas cylinder, a valve unit fixed to the gas container () and a protective cap () arranged around the said valve unit, the protective cap () comprising an opening () in which a rotary control member () is housed. The opening () is bordered by a protruding brim () jutting out from the external surface of the body () of the protective cap (). The protruding brim () comprises a cutout () forming a reading window so that marks or markings () corresponding to gas flow-rate values can be read.

Cap with a brim protecting the rotary control member of a gas container valve unit

A valve for pressurized fluid, with or without incorporated pressure-reducing valve, comprising a body accommodating a fluid circuit having an upstream end designed to be placed in communication with a reserve of pressurized fluid and a downstream end designed to be placed in communication with a using device, the circuit comprising an isolation valve element in order to selectively close off the circuit, the valve element being controlled by a lever mounted so as to pivot on the body between a rest position in which the isolation valve element is held in a position of closing the circuit and an active position in which the lever moves the isolation valve element into a position of opening the circuit , wherein the lever comprises at least one opening, wherein the valve comprises a functional abutment mounted on the body and wherein only in the rest position the opening accommodates within it a portion of the functional abutment mounted on the body.
