  • the document EP-A-2918893 offers a gas bottle equipped with a valve with an integrated regulator or RDI protected by a rigid cover comprising openings giving access to organs or elements of the valve which are located in the internal volume of the cover, for example to connectors or end pieces gas inlet or outlet used when filling the bottle when it is empty or, conversely, when withdrawing gas.
  • a pressure gauge is arranged in the upper half, also called the upper part, of the cowling so as to provide an indication of the gas pressure to the user.
  • EP-A-2918892 offers a cover similar to the previous one but where the pressure gauge has been replaced by an electronic display screen.
  • the screen can be touchscreen. In both cases, the screen is electrically powered by one or more batteries or electric cells.
  • US-A-10,151,405 teaches a gas container, in particular a gas cylinder, comprising a fluid distribution valve equipped with an electronic measuring device with a digital display with a first region in the form of a disc portion comprising an arcuate edge and a arcuate bar graph positioned along the arcuate edge, and a second rectangular-shaped region.
  • FR-A-3033385 And US-A-9,285,078 offers other gas containers equipped with an electronic measuring device with a rectangular digital display.
  • the user must also be able to easily access the means allowing information or menus to be scrolled on the digital display, for example flow rate/autonomy pairs or a quantity of gas expressed in units of pressure or volume, and this , again, even when the container is equipped with a protective covering.
  • the problem is therefore to propose a gas container, in particular a gas bottle, comprising a fluid distribution tap equipped with an electronic measuring device with an improved digital display, which makes it possible to display various information useful to the user and does not pose the aforementioned problems, and makes it possible to achieve the aforementioned objectives, even when it is equipped with a protective covering used to protect the gas distribution valve, in particular an RDI.
  • the solution of the invention then relates to a gas container, in particular a pressurized gas cylinder, comprising a gas distribution valve and an electronic measuring device arranged on said gas distribution valve, said electronic measuring device comprising a box comprising a front panel comprising a digital display, ie an information display screen or others, the digital display comprising at least two juxtaposed information display regions comprising a first region in the form of a disc portion comprising an arcuate edge circle and an arcuate bar graph positioned along the arcuate edge, and a second region of rectangular shape, characterized in that the electronic measuring device further comprises a digitally activated button and an indicator light arranged in said front panel, the digital display being arranged in the center of the front panel of the electronic measuring device, and the button and the indicator light being arranged above the digital display.
  • Fig. 1 represents an embodiment of the front panel 33 of the electronic device 3 housed in the protective covering 1 of a gas container 20 according to the invention, as shown schematically in Fig. 3 , comprising an information display 4 used to display information, data, quantities, etc. useful to the user, in particular pressure, flow, autonomy etc..., as well as icons, alarms...
  • the fluid container 20 is here a pressurized gas cylinder, of vertical axis AA, comprising a cylindrical body 29 defining an internal volume for storing gas under high pressure, typically up to 140 to 300 bar abs, or even beyond 300 bar abs, and a neck (not visible) comprising an orifice communicating with the internal volume and allowing the gas to be withdrawn from the internal volume or, conversely, to fill it when it is empty .
  • the electronic device 3 is attached to the fluid distribution valve 21, as illustrated in Fig. 5 and Fig. 6 .
  • the protective covering 1 comprises a rigid body 2 which is supported on and/or secured to the gas distribution valve 21 and/or to the gas container 20.
  • the protective covering 1 is formed of a rigid body 2 formed of two sub-shells 2a, 2b which are connected and secured to each other by sandwiching the housing 34 of the electronic device 3, so as to that it is housed in a first opening 25 of the body 2 of the cowling 1.
  • the two sub-shells 2a, 2b also sandwich the fluid distribution valve 21.
  • the two sub-shells 2a, 2b can be fixed to each other by screws or the like.
  • the gas distribution nozzle 27 and the rotary wheel 22 arranged around the nozzle 27 are housed in a second opening 23 also made in the protective cover 1 rigid protection 1 so as to emerge at the level of the external surface of said cover 1.
  • the gas distribution nozzle 21 projects from the center of the rotary steering wheel 22 and projects away towards the outside of the cowling 1.
  • the first opening 25 and the second opening 23 are formed “straddling” between the two subshells 2a, 2b.
  • the body 2 of the protective covering 1, that is to say its two sub-shells 2a, 2b, can be made of polymer or metal or metal alloy, or both.
  • the protective covering 1 is coaxial (axis AA) to the gas bottle 20.
  • the protective cover 1 is provided with a carrying handle 7 connected to the cover body 2 by support posts 8.
  • the carrying handle 7 surmounts the cover body 2 and faces the front panel 33 of the electronic device 3, as visible on the Fig. 3 .
  • the carrying handle 7 is sized to be able to be grasped manually by a user in order to allow easy handling and/or transport of the gas cylinder/RDI/cowl assembly.
  • a mobile hanging device or system 9 is also provided (partially visible in Fig. 3 ), preferably pivoting, allowing the gas bottle/RDI/covering assembly to be hung on a support, such as a hospital bed bar, on a stretcher or on a rod or the like.
