Le robinet 1 pour fluide sous pression représenté à la [Fig. 1] comprend un corps 2 abritant un circuit 3 interne de fluide ayant une extrémité 4 amont (par exemple inférieure) destinée à être mise en relation avec une réserve de fluide sous pression et une extrémité aval 5 (par exemple latérale) destinée à être mise en relation avec un appareil utilisateur via un raccord de sortie, par exemple un raccord rapide.The valve 1 for pressurized fluid shown in [ Fig. 1 ] comprises a body 2 housing an internal fluid circuit 3 having an upstream end 4 (for example lower) intended to be connected with a reserve of pressurized fluid and a downstream end 5 (for example lateral) intended to be connected with a user device via an outlet connector, for example a quick coupling.

Le circuit 3 interne comprend au moins une vanne 6 de contrôle du débit dans le circuit 3 (vanne d'isolation et/ou de régulation de pression et/ou de débit) et tout autre organe approprié.The internal circuit 3 comprises at least one flow control valve 6 in the circuit 3 (isolation valve and/or pressure and/or flow control valve) and any other suitable device.

La vanne 6 est commandée par un organe 7 d'actionnement mobile, par exemple un levier articulé sur le corps 2, pour commander cette dernière (pour l'ouverture ou la fermeture de par exemple) .The valve 6 is controlled by a movable actuation member 7, for example a lever articulated on the body 2, to control the latter (for the opening or closing of for example).

Selon une particularité avantageuse, la sortie de soutirage est déportée à l'extérieur du corps 2. Par exemple, le robinet 1 comprend un tuyau 8 de soutirage comprenant une première extrémité reliée rigidement au corps 2 (soudage et/ou vissage par exemple) au niveau de l'extrémité aval 5 du circuit 3 interne de fluide et une seconde extrémité espacée du corps 2 et munie du raccord 15 de sortie.According to an advantageous feature, the draw-off outlet is offset outside the body 2. For example, the valve 1 comprises a draw-off pipe 8 comprising a first end rigidly connected to the body 2 (welding and/or screwing for example) to the level of the downstream end 5 of the internal fluid circuit 3 and a second end spaced from the body 2 and provided with the connector 15 of the outlet.

Par exemple le tuyau 8 de soutirage est rigide et peut être composé d'un métal ou alliage, par exemple du cuivre.For example the withdrawal pipe 8 is rigid and can be made of a metal or alloy, for example copper.

Comme illustré, le tuyau 8 de soutirage peut comporter au moins un coude ou cintrage définissant un changement de direction entre ses deux extrémités. Ceci permet de déporter l'extrémité 15 munie du raccord de sortie dans une position déterminée sans trop s'éloigner du corps 2.As illustrated, the withdrawal pipe 8 may include at least one bend or bend defining a change in direction between its two ends. This makes it possible to offset the end 15 provided with the outlet connector in a determined position without moving too far from the body 2.

Par exemple, le robinet 1 comprend une face avant, une face arrière est deux faces latérales. L'extrémité aval 5 du circuit 3 interne de fluide peut être située sur une face latérale du corps 2, la seconde extrémité du tuyau 8 de soutirage peut être orientée vers la face avant (cette face avant peut comporter par exemple d'autres fonctions ou composants, par exemple un régulateur de débit 16, un manomètre ...) .For example, the faucet 1 comprises a front face, a rear face and two side faces. The downstream end 5 of the internal fluid circuit 3 can be located on a side face of the body 2, the second end of the withdrawal pipe 8 can be oriented towards the front face (this front face can comprise for example other functions or components, for example a flow regulator 16, a pressure gauge, etc.).

Comme illustré, le robinet 1 peut comporter une coque 9 de protection monté autour d'au moins une partie du corps 2 du robinet. Au moins une partie du tuyau 8 de soutirage peut être ainsi est abrité dans la coque 9. Le raccord 15 de sortie peut débouche via une ouverture de la coque 9. cf. [Fig. 2], [Fig. 4] ou [Fig. 5] par exemple.As illustrated, the valve 1 may include a protective shell 9 mounted around at least a part of the body 2 of the valve. At least part of the withdrawal pipe 8 can thus be housed in the shell 9. The outlet connector 15 can emerge via an opening in the shell 9. cf. [ Fig. 2 ], [ Fig. 4 ] Where [ Fig. 5 ] for example.

Ceci permet de déporter le raccord 15 de sortie et simplifier le corps tout en donnant l'impression d'une compacité et d'une unité au robinet 1.This makes it possible to offset the outlet connector 15 and simplify the body while giving the impression of compactness and unity to the valve 1.

Le robinet 1 peut ainsi comporte au moins un organe 18 électronique tel que l'un au moins parmi : un microprocesseur, une antenne de communication sans fil, ou autre. La seconde extrémité du tuyau 8 de soutirage (par exemple dans la partie inférieure) peut ainsi être espacée dudit organe 18 électronique (par exemple dans la partie inférieure), par exemple d'une distance comprise entre 10 et 200mm (ou toute distance nécessaire pour ne pas perturber le bon fonctionnement de l'organe électronique 18 ou toute distance suffisante pour être éloignée de de cet organe 18 et faciliter l'intégration dans le robinet et/ou la coque 9.The tap 1 can thus comprise at least one electronic device 18 such as at least one of: a microprocessor, a wireless communication antenna, or other. The second end of the withdrawal pipe 8 (for example in the lower part) can thus be spaced from said electronic device 18 (for example in the lower part), for example by a distance between 10 and 200 mm (or any distance necessary for not to disturb the proper functioning of the electronic component 18 or any distance sufficient to be away from this component 18 and to facilitate integration into the valve and/or the shell 9.

Ceci permet un positionnement de la sortie de fluide relativement plus loin du corps 2 que selon l'art antérieur. Ceci permet en outre de simplifier la structure et la conception du robinet 1 et également d'éloigner de pièces métalliques d'une éventuelle électronique sensible à des perturbations. De plus, cette structure permet en outre de faciliter l'intégration et le positionnement du raccord 15 par rapport au robinet et la coque.This allows positioning of the fluid outlet relatively farther from the body 2 than according to the prior art. This also makes it possible to simplify the structure and the design of the valve 1 and also to keep metal parts away from any electronics sensitive to disturbances. In addition, this structure also facilitates the integration and positioning of the connector 15 relative to the valve and the hull.

Comme illustré dans les exemples de [Fig. 2], [Fig. 4] ou [Fig. 5], la coque 9 comporte une portion tubulaire définissant une poignée 19 de manutention et au moins une portion du tuyau 8 de soutirage est abrité dans ladite poignée 19. L'extrémité du raccord 15 de sortie peut faire plus ou moins saillie en dehors de la coque (poignée) pour permettre son raccordement à un raccordement d'un utilisateur (raccord 10 conjuguée d'un flexible 20 d'un appareil receveur du fluide par exemple).As illustrated in the examples in [ Fig. 2 ], [ Fig. 4 ] Where [ Fig. 5 ], the shell 9 comprises a tubular portion defining a handling handle 19 and at least a portion of the withdrawal pipe 8 is housed in said handle 19. The end of the outlet connector 15 can project more or less outside of the shell (handle) to allow its connection to a connection of a user (connection 10 combined with a hose 20 of a device receiving the fluid for example).

Comme illustré à la [Fig. 2], le corps 2 peut comprendre une extrémité inférieure de montage munie d'organe(s) 14 d'accrochage mobile(s) destiné(s) à coopérer avec un ou des organes d'accrochage complémentaires 15 pour former un système de connexion rapide du robinet 1 sur une source de gaz ou un circuit. Par exemple le(s) organes 14, 15 d'accrochage peuvent comprendre un système à billes et/ou griffes coopérant avec des logement(s) rainure(s) et/ou un système de raccord vissé (filetage et taraudage).As shown in [ Fig. 2 ], the body 2 may comprise a lower mounting end provided with movable attachment member(s) 14 intended to cooperate with one or more complementary attachment members 15 to form a quick connection system tap 1 on a gas source or circuit. For example the attachment member(s) 14, 15 may comprise a ball and/or claw system cooperating with groove(s) housing(s) and/or a screw connection system (thread and internal thread).

Ce robinet 1 peut par exemple faire partie du dispositif 100 de fourniture de fluide sous pression illustré à la [Fig. 2] et peut notamment constituer le second robinet mentionné ci-dessous.This valve 1 can for example be part of the device 100 for supplying pressurized fluid illustrated in [ Fig. 2 ] and may in particular constitute the second valve mentioned below.

Ce dispositif, 100 comprend premier ensemble 11, 12 fonctionnel comportant au moins une bouteille 12 de fluide sous pression reliée à un premier robinet 11.This device 100 comprises a first functional assembly 11, 12 comprising at least one bottle 12 of pressurized fluid connected to a first valve 11.

Ce premier 11 robinet comprend un circuit 16 interne de fluide comportant un clapet 17 d'isolation.This first valve 11 comprises an internal fluid circuit 16 comprising a valve 17 for isolation.

Le dispositif 100 comporte un second robinet 1 formant une entité physique distincte du premier robinet 11. Le second robinet 1 est muni d'un circuit 3 interne de fluide. Le premier 1 robinet et le second 11 robinet comprenant des organes (4, 15 d'accrochage respectifs formant un système de connexion rapide male/femelle amovible du second robinet 1 sur le premier robinet 11. Un tel dispositif peut être conforme à celui décrit par exemple dans le document FR3054290A1 .The device 100 comprises a second valve 1 forming a separate physical entity from the first valve 11. The second valve 1 is provided with an internal circuit 3 of fluid. The first 1 valve and the second 11 valve comprising respective attachment members (4, 15) forming a removable male/female quick connection system of the second valve 1 on the first valve 11. Such a device may conform to that described by example in document FR3054290A1 .
