Le dispositif 1 de fourniture de gaz illustré aux figures 1 à 3 comprend classiquement un cadre 2 support, comprenant par exemple une armature parallélépipédique abritant une pluralité de bouteilles 3 de fluide sous pression.  The gas supply device 1 illustrated in FIGS. 1 to 3 conventionally comprises a support frame 2 comprising, for example, a parallelepipedal frame housing a plurality of pressurized fluid bottles 3.

Par exemple, les bouteilles 3 sont disposées en faisceau verticalement sur un fond (seize bouteilles 3 dans cet exemple non limitatif). Les orifices des bouteilles 3 sont reliés à circuit 4, 5 fluidique pour assurer le soutirage ou le remplissage des bouteilles 3.  For example, the bottles 3 are arranged in a beam vertically on a bottom (sixteen bottles 3 in this non-limiting example). The orifices of the bottles 3 are connected to a fluid circuit 4, 5 to ensure the withdrawal or filling of the bottles 3.

Le circuit 4, 5 comporte une première extrémité 6 de raccordement reliée aux bouteilles 3 via un premier clapet 7 d'isolation pour permettre le remplissage et le soutirage des bouteilles 3. Le circuit comprend une seconde extrémité 8 de raccordement distincte reliée aux orifices des bouteilles 3 via un second clapet 9 d'isolation et un détendeur 10 de pression. Comme illustré à titre d'exemple à la figure 1 , le détendeur 10 et le clapet 9 d'isolation sont disposés en série dans cet ordre entre les bouteilles 3 et la seconde extrémité 8 de raccordement. Bien entendu, il est possible d'envisager de placer le second clapet 9 d'isolation en amont du détendeur 10 (c'est-à-dire entre les bouteilles 3 et le détendeur 10). La seconde extrémité 8 de raccordement est prévue pour permettre le soutirage de fluide. The circuit 4, 5 comprises a first connection end 6 connected to the bottles 3 via a first isolation valve 7 to allow the filling and withdrawal of the bottles 3. The circuit comprises a second end 8 of separate connection connected to the orifices of the bottles 3 via a second isolation valve 9 and a pressure regulator 10. As illustrated by way of example in FIG. 1, the expansion valve 10 and the isolation valve 9 are arranged in series in this order between the bottles 3 and the second connection end 8. Of course, it is possible to consider placing the second isolation valve 9 upstream of the expander 10 (that is to say between the bottles 3 and the expander 10). The second end 8 of connection is provided to allow the withdrawal of fluid.

Le cadre 2 support comprend sur une de ses faces, dite « face avant », un panneau 20 d'interface pour un utilisateur comprenant au moins une ouverture d'accès au circuit 4, 5.  The support frame 2 comprises on one of its faces, called the "front face", an interface panel 20 for a user comprising at least one access opening to the circuit 4, 5.

Le dispositif comporte un organe 16 de commande manuelle du second clapet 9 d'isolation comprenant un levier pivotant. Par exemple, et sans que ce soit limitatif pour autant, le levier 16 de commande et sa vanne associée peuvent comprendre tout ou partie des caractéristiques des dispositifs décrits dans les documents FR2735209A1 , FR2828922A1 ou FR2970314A1 .  The device comprises a body 16 for manual control of the second isolation valve 9 comprising a pivoting lever. For example, and without this being limiting, the control lever 16 and its associated valve may comprise all or part of the characteristics of the devices described in the documents FR2735209A1, FR2828922A1 or FR2970314A1.

De plus, le panneau 20 d'interface comprend une fente 21 d'accès au levier In addition, the interface panel 20 includes a lever access slot 21

16. Le levier 16 est mobile en rotation au niveau d'une de ses extrémités sur un corps de vanne ou sur un corps de robinet. Le levier 16 est notamment mobile au travers de la fente 21 entre une première position dans laquelle le levier 16 est situé dans le plan du panneau 20 d'interface ou en retrait de ce dernier au sein du volume cadre 2 (cf. figures 5 et 7) et une seconde position dans laquelle au moins une partie du levier 16 fait saille par rapport au panneau 20 d'interface vers l'extérieur du cadre 2 et au travers de la fente 21 (cf. figure 6). 16. The lever 16 is rotatable at one of its ends on a valve body or on a valve body. The lever 16 is in particular movable through the slot 21 between a first position in which the lever 16 is situated in the plane of the interface panel 20 or withdrawing from the latter within the frame volume 2 (see FIGS. 7) and a second position in which at least a portion of the lever 16 protrudes from the interface panel 20 towards the outside of the frame 2 and through the slot 21 (see Figure 6).

C'est-à-dire que, dans sa première position, le levier 16 peur être dans le plan du panneau 20 d'interface ou en retrait de ce dernier à l'intérieur du volume du cadre 2. Dans sa seconde position, l'extrémité terminale au moins du levier 16 fait saillie par rapport au panneau 20 en direction de l'extérieur du cadre 2.  That is, in its first position, the lever 16 can be in the plane of the interface panel 20 or withdrawn from it within the frame 2 volume. In its second position, the at least one end end of the lever 16 protrudes from the panel 20 towards the outside of the frame 2.

La première position correspond de préférence à une commande de la fermeture du premier clapet 7 d'isolation tandis que dans la seconde position le levier commande l'ouverture du premier clapet 7 d'isolation.  The first position preferably corresponds to a control of the closing of the first isolation valve 7 while in the second position the lever controls the opening of the first isolation valve 7.

Cette configuration permet de renseigner visuellement l'utilisateur sur l'état d'ouverture/fermeture du clapet 9 d'isolement (visible à distance de plusieurs mètres).  This configuration makes it possible to visually inform the user of the state of opening / closing of the isolation valve 9 (visible at a distance of several meters).

Comme illustré à la figure 3, le levier 16 peut avoir la forme générale d'une tige (à la figure 3 le levier est représenté simultanément dans deux positions extrêmes respectivement basse et relevée). En variante et comme illustré aux figures 4 à 7, le levier 16 peut comporter un corps ayant la forme générale d'une tige dont l'extrémité libre comporte une tête élargie par rapport au reste du corps. Ainsi, dans sa seconde position, la tête du levier 16 fait saille par rapport au panneau 20 d'interface au travers de la fente 21 . Par exemple la tête du levier 16 a la forme d'un anneau pouvant comprendre, en son centre, des nervures croisées. As illustrated in FIG. 3, the lever 16 may have the general shape of a rod (in FIG. 3 the lever is represented simultaneously in two positions extremes respectively low and raised). Alternatively and as illustrated in Figures 4 to 7, the lever 16 may comprise a body having the general shape of a rod whose free end has an enlarged head relative to the rest of the body. Thus, in its second position, the head of the lever 16 protrudes with respect to the interface panel 20 through the slot 21. For example, the head of the lever 16 is in the form of a ring which may comprise, at its center, crossed ribs.

Bien entendu, le levier 16 peut avoir toute autre forme appropriée.  Of course, the lever 16 may have any other suitable form.

De préférence, la fente 21 a une forme générale correspondant à la forme du contour extérieur du levier 16 (avec par exemple un jeu de quelques millimètres ou centimètres entre le bord du levier 16 et le bord de la fente 21 .  Preferably, the slot 21 has a general shape corresponding to the shape of the outer contour of the lever 16 (with for example a clearance of a few millimeters or centimeters between the edge of the lever 16 and the edge of the slot 21.

Comme illustré à la figure 4, lorsque le levier 16 est dans sa première position, par exemple lors de la livraison du dispositif, un sceau 22 de garantie peut être prévu pour garantir la non utilisation du dispositif après le remplissage des bouteilles 3.  As illustrated in FIG. 4, when the lever 16 is in its first position, for example when the device is delivered, a seal 22 of guarantee can be provided to guarantee the non-use of the device after filling the bottles 3.

Le sceau 22 de garanti a par exemple la forme d'une languette plane et comprend une extrémité de préhension manuelle.  The seal 22 guaranteed for example has the shape of a flat tongue and includes a manual gripping end.

Dans sa première configuration correspondant à la figure 4 (sceau 22 non retiré), une première extrémité du sceau 22 est fixée au panneau 20 au niveau de la fente 21 et une seconde extrémité du sceau est fixée au levier 16 situé dans sa première position. Dans cette première configuration, le sceau 22 forme une butée mécanique empêchant le déplacement du levier 16 de la première vers sa seconde position.  In its first configuration corresponding to Figure 4 (seal 22 not removed), a first end of the seal 22 is attached to the panel 20 at the slot 21 and a second end of the seal is attached to the lever 16 in its first position. In this first configuration, the seal 22 forms a mechanical stop preventing the lever 16 from moving from the first to its second position.

Le sceau 22 est fixé au panneau 20 et au levier par déformation élastique ou collage ou tout autre mode approprié.  The seal 22 is attached to the panel 20 and the lever by elastic deformation or gluing or any other appropriate mode.

Le sceau 22 peut comprendre une zone de rupture aménagée pour disposer manuellement le sceau 22 dans une seconde configuration retirée dans laquelle la liaison fixation du sceau 22 au panneau 20 d'interface et/ou au levier 16 est rompue. C'est-à-dire que dans sa seconde configuration, le levier 16 peut être déplacé. De préférence, le retrait du sceau 22 provoque une rupture irréversible de l'intégrité de ce dernier. C'est-à-dire que le sceau 22 est cassé ne peut plus être repositionné sans la première configuration.  The seal 22 may comprise a rupture zone arranged to manually arrange the seal 22 in a second withdrawn configuration in which the binding attachment of the seal 22 to the interface panel 20 and / or the lever 16 is broken. That is, in its second configuration, the lever 16 can be moved. Preferably, the removal of the seal 22 causes an irreversible rupture of the integrity of the latter. That is, the seal 22 is broken can not be repositioned without the first configuration.

Avantageusement, le levier 16 peut comporter une zone d'affaiblissement telle qu'une diminution localisée d'épaisseur pour faciliter sa rupture en cas de choc et limiter l'effort transmis au second clapet 9 (notamment dans le cas où le levier est dans sa seconde position). Advantageously, the lever 16 may comprise a zone of weakness such as a localized reduction in thickness to facilitate its break in case of shock and limit the force transmitted to the second valve 9 (especially in the case where the lever is in its second position).

Cette zone de fragilité du levier 16 peut notamment permettre la casse du levier 16 en cas de choc latéral quand le clapet 9 correspondant est ouvert, sans affecter l'intégrité du dispositif. Après rupture, le levier 16 peut conserver une longueur résiduelle permettant sa manipulation en mode dégradé (à la main ou via un outil).  This zone of weakness of the lever 16 can in particular allow the breakage of the lever 16 in the event of a side impact when the corresponding valve 9 is open, without affecting the integrity of the device. After breaking, the lever 16 may retain a residual length allowing its handling in degraded mode (by hand or via a tool).

Comme visible aux figures 4 à 7, la première extrémité 6 de raccordement comporte de préférence un raccord de remplissage situé en regard du panneau 20 d'interface et ce panneau 20 comprend une première ouverture 23 d'accès dédiée à la première extrémité 6 de raccordement.  As can be seen in FIGS. 4 to 7, the first connection end 6 preferably comprises a filling connector located opposite the interface panel 20 and this panel 20 comprises a first access opening 23 dedicated to the first connection end 6 .

De même, la seconde extrémité 8 de raccordement peut comporter un raccord 18 de soutirage situé en regard d'une seconde ouverture 24 du panneau 20. Ce raccord de soutirage est prévu pour recevoir un raccord complémentaire d'un flexible 17 de soutirage (cf. figures 4 à 6).  Similarly, the second end 8 of connection may comprise a connection 18 for withdrawal located opposite a second opening 24 of the panel 20. This connection of withdrawal is provided to receive a complementary connection of a hose 17 withdrawal (cf. Figures 4 to 6).

Le panneau 20 peut comporter au moins un cache 27 mobile (par exemple coulissant ou pivotant) pour permettre d'ouvrir (cf. figure 4, 5, 6 et partie droite de la figure 8) ou fermer (cf. figures 7 et partie gauche de la figure 8) l'accès à la première extrémité 6 ou seconde extrémité 8 de raccordement à la façon d'une fenêtre.  The panel 20 may comprise at least one mobile cover 27 (for example sliding or pivoting) to allow opening (see FIGS. 4, 5, 6 and right part of FIG. 8) or closing (see FIGS. of Figure 8) access to the first end 6 or second end 8 connection in the manner of a window.

Le circuit comprend de préférence un manomètre 26 qui peut être situé en regard d'une troisième ouverture 25 du panneau 20.  The circuit preferably comprises a pressure gauge 26 which can be located opposite a third opening 25 of the panel 20.

Comme illustré à titre d'exemple à la figure 1 , le circuit 4, 5 peut comprendre, disposée en série entre le détendeur 10 de pression et la second extrémité 8 de raccordement, une soupape 1 1 de sécurité à ouverture vers l'atmosphère lorsqu'elle est soumise à une pression supérieure à un seuil déterminé. Comme illustré à la figure 1 , la soupape 1 1 est disposée en aval du second clapet 9 d'isolation, c'est-à-dire entre le second clapet 9 d'isolation et la seconde extrémité 8. Bien entendu, alternativement cette soupape 1 1 pourrait être disposée entre le détendeur 10 et le second clapet 9 d'isolation.  As illustrated by way of example in FIG. 1, the circuit 4, 5 may comprise, arranged in series between the pressure regulator 10 and the second connection end 8, a safety valve 1 1 with an opening towards the atmosphere when it is subjected to a pressure greater than a determined threshold. As illustrated in FIG. 1, the valve 11 is disposed downstream of the second isolation valve 9, that is to say between the second isolation valve 9 and the second end 8. Of course, alternatively this valve 1 1 could be arranged between the expander 10 and the second valve 9 insulation.

La soupape 1 1 de sécurité est tarée par exemple pour ouvrir un passage de gaz vers l'atmosphère lorsqu'elle est soumise à un seuil de pression compris entre 50 et 310bar (ou 4500 psi) et de préférence compris entre 150 et 200 bar. On conçoit donc aisément que le dispositif, tout en étant de structure simple et peu coûteuse, permet à l'utilisateur d'identifier facilement les divers organes et interfaces (raccords, clapet...) et d'utiliser ces derniers avec une grande ergonomie et sécurité. The safety valve 1 1 is tared for example to open a passage of gas to the atmosphere when it is subjected to a pressure threshold of between 50 and 310 bar (or 4500 psi) and preferably between 150 and 200 bar. It is therefore easy to understand that the device, while being simple and inexpensive structure, allows the user to easily identify the various organs and interfaces (fittings, valve ...) and use them with great ergonomics and security.

En particulier, le panneau 20 d'interface peut séparer clairement les parties de remplissage et de soutirage du circuit. Ceci permet de limiter les risques de confusion dans les branchements et actionnement des clapets. A cet effet, le panneau 20 d'interface peut comprendre des zones de textes ou symbole et couleurs pour encore mieux faciliter l'utilisation.  In particular, the interface panel 20 can clearly separate the filling and withdrawing portions of the circuit. This makes it possible to limit the risks of confusion in the connections and actuation of the valves. For this purpose, the interface panel 20 may include text or symbol and color areas to further facilitate the use.

Le cache 27 permet de limiter l'accès au raccord de remplissage. Ce cache The cover 27 makes it possible to limit access to the filling connection. This cache

27 limite les risques d'une utilisation accidentelle du premier clapet 7 d'isolation. Cet accès peut être obtenu par une action volontaire de l'utilisateur en cas de besoin spécifique de pression ou de débit supérieur à ce que peut proposer la vanne à pression détendue. Les risques de dégradations et de salissures sont également réduits. 27 limits the risks of accidental use of the first valve 7 insulation. This access can be obtained by a voluntary action of the user in case of specific need for pressure or flow greater than what can be offered by the pressure relief valve. The risks of damage and dirt are also reduced.

Le panneau 20 d'interface a l'avantage, en cas de maintenance et après son démontage, de mettre a disposition l'ensemble des éléments de mise en œuvre de gaz sous pression et ainsi d'en faciliter leur démontage pour l'opérateur sans que ce dernier n'ait à adopter une posture peu confortable, préjudiciable pour ses membres, par exemple.  The interface panel 20 has the advantage, in the event of maintenance and after dismantling, of making available all the implementation elements of gas under pressure and thus of facilitating their dismounting for the operator without that the latter has to adopt an uncomfortable posture, prejudicial for its members, for example.
