The invention relates to a pressurized fluid cylinder, a member for acquiring, storing and processing data, and at least one data display device. The valve comprises a sensor which detects the position of a manual control member, and a pressure sensor for measuring the pressure inside the storage space of a fluid cylinder. The data acquisition, storage and processing member is designed to: calculate an actual value for the amount of fluid remaining and/or drawn off; calculate a theoretical value for the amount of fluid remaining and/or drawn of on the basis of the regulation performed by the regulating member and measured by the position of the control member compare the actual value based on the measurement of the pressure sensor with the theoretical value; and generate a warning signal if the difference between these actual and theoretical values is greater than a specific safety threshold.

Valve for a pressurized fluid cylinder and corresponding cylinder

The invention relates to a valve for a pressurized fluid cylinder comprising a member for manually controlling a flow-regulating member, a sensor for detecting the position of the member for manually controlling the regulating member, a data acquisition, storage, and processing member, and a display for information relating to the fluid flow and/or pressure imposed by the regulating member and/or the valve use mode, wherein when the manual control member is disposed in an intermediate position between two respective adjacent values of the flow and/or pressure of the fluid allowed to pass from the upstream end to the downstream end, the data acquisition, storage and process member is designed to suppress the display information.

The invention concerns a pressurized fluid cylinder equipped with a valve accommodating a first draw-off circuit, the valve comprising a member for regulating the flow and/or the pressure of the fluid drawn off via a member for manually controlling the regulating member, the valve comprising an electronic device for displaying data concerning the amount of fluid contained in a cylinder which is connected to the valve, the electronic display device comprising a member for acquiring, storing, and processing data, and at least one data display connected to the data acquisition, storage and processing member.

Pressurized fluid cylinder comprising an electronic data-display device

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.
