- valve also called valve, namely here an integrated pressure regulator valve or RDI, including an elastic connecting element 5, which during a major shock, allows to keep the integrity of the part of the RDI exposed to high pressure (HP), as schematized in Figure 1 , in particular at a pressure of up to 300 to 400 bar abs.
- HP high pressure
- the valve block 1 which is for example made of brass and / or stainless steel, houses an internal gas passage 4, also called the first withdrawal circuit, comprising an upstream first end communicating with the storage volume of a bottle 7 of fluid under pressure (cf. Figure 3 and a second downstream end, typically provided with a gas outlet fitting, for connection to a withdrawn gas user device.
- an internal gas passage 4 also called the first withdrawal circuit, comprising an upstream first end communicating with the storage volume of a bottle 7 of fluid under pressure (cf. Figure 3 and a second downstream end, typically provided with a gas outlet fitting, for connection to a withdrawn gas user device.
- the internal gas passage 4 conveys the high pressure gas (HP) from the pressurized gas cylinder 7 on which the RDI is mounted.
- the internal gas passage 4 comprises a regulating member of the flow rate and / or the pressure of the gas withdrawn between the upstream and downstream ends.
- the RDI also comprises a manual control member of the regulating member, mounted movably relative to the valve body 1 and cooperating with the regulating member to control the flow rate and / or the fluid pressure allowed to flow from the upstream end towards the downstream end according to the position of the control member with respect to the valve body 1.
- the RDI further comprises an electronic indicating device 3, that is to say an electronic data indicating device (s) relative to the fluid contained in a bottle on which is mounted the valve 1, for example a digital manometer.
- an electronic indicating device 3 that is to say an electronic data indicating device (s) relative to the fluid contained in a bottle on which is mounted the valve 1, for example a digital manometer.
- the electronic indicator device 3 comprises an electronic card making it possible to acquire, store and process data, in particular the pressure of the gas measured by a pressure sensor, and at least one data display 12, namely a digital display, connected to the data acquisition and data acquisition member, to transmit to the latter a signal representative of the flow rate and / or the fluid pressure imposed by the regulating member.
- the electronic indicator device 3 comprises a rigid outer casing 13, for example made of polymer and / or metal, which forms a protective shell serving to contain and protect in particular the electronic card. It may also contain a source of electrical energy used to power the electronic card and / or the display and / or other elements (e.g. sensor ...), for example a battery, a battery or the like.
- the rigid housing 13 also carries the data display 12, preferably a digital display.
- a rigid connecting element 2 interposed between the electronic indicator device 3 and the valve body 1, mechanically secures the electronic indicator device 2 to the valve body 1.
- the rigid connecting element 2 forms a connection or tip crossed by an internal channel 6 of gas which is in fluid communication with the internal passage 4 of the body 1 of the RDI.
- the internal gas channel 6 brings the gas pressure to a pressure sensor (not shown) making it possible to measure the pressure of the fluid HP conveyed by the internal passage 4.
- the pressure sensor then delivers a pressure signal to the electronic card of the device electronic indicator 3.
- the pressure sensor can be arranged on or integrated with the connecting element 2.
- the elastic or flexible connecting element 5 is arranged between the rigid connecting element 2 and the electronic indicating device 3, and mechanically secures the electronic indicator device 3 to the rigid connecting element. 2.
- the elastic connecting element 5 is arranged between the rigid housing 13 of the electronic indicator device 3 and the rigid connecting element 2.

- information is transferred, for example from a pressure signal measured by the pressure sensor, to the electronics, that is to say the electronic card of the electronic indicating device 3. .
- the elastic connecting element 5 is designed and adapted to absorb the shock received by the electronic indicator device, for example in the event of a fall, and thus to cancel or limit the transmission of the resulting forces to the element rigid connection and prevent it from breaking.
- the electronics does not stop working because it remains connected to the pressure sensor.
- the HP portion of the block 1 is preserved and remains under pressure, which increases the safety for the user.
- the electronic indicator device 3 in the event of an impact, can therefore accompany the bending of the elastic connecting element without breaking and the safety of the user is retained.
- one (or more) fluidic sealing element such as an O-ring 8 is arranged between the connecting element 2 and the body of the valve block 1, as illustrated in FIG. Figure 1 in order to avoid possible gas leaks between them.
- the gas distribution valve may comprise other conventional components, such as a rotary operating wheel 9, a threaded end piece 10, cylindrical or frustoconical, fixing the gas distribution valve on a collar of gas bottle 7, a gas outlet fitting, a filling fitting ...
- gas distribution valve may also be protected by a protective cover or "hat” (not shown), when mounted on a gas container 7, in particular a cylindrical gas cylinder, such as shown in Figure 3 .
- a gas distribution valve such as an RDI, according to the invention may advantageously be mounted on a gas cylinder 7 used to store or to distribute a gas under pressure, in particular a medical gas, be it a pure gas or a gas.
