- la figure 6 représente vue similaire à celle de la figure 5 et agrandie illustrant le dispositif de fourniture de fluide dans un état verrouillé. Le dispositif de fourniture de fluide sous pression, notamment de gaz sous pression comprend un réservoir 2 de fluide sous pression muni d'un orifice dans lequel est fixé un premier robinet 3. - Figure 6 shows a view similar to that of Figure 5 and enlarged illustrating the fluid supply device in a locked state. The device for supplying fluid under pressure, in particular pressurized gas, comprises a reservoir 2 of pressurized fluid provided with an orifice in which a first valve 3 is fixed.
Le premier robinet 3 comprend un circuit 4 interne de fluide comprenant au moins un clapet 5 d'isolation et de préférence plusieurs clapets disposés en série.  The first valve 3 comprises an internal fluid circuit 4 comprising at least one isolation valve 5 and preferably several valves arranged in series.
Comme illustré dans l'exemple de la figure 4, le premier robinet 3 peut comprendre un corps de forme générale cylindrique abritant, dans son circuit 4 interne, un clapet 20 pare-poussière disposé en série avec au moins un clapet 5 d'isolement.  As illustrated in the example of Figure 4, the first valve 3 may comprise a generally cylindrical body housing, in its internal circuit 4, a valve 20 dust cover arranged in series with at least one valve 5 isolation.
Le dispositif comprend un organe 6 de transfert de gaz formant une entité physique distincte du robinet 3 et du réservoir 2.  The device comprises a gas transfer member 6 forming a physical entity distinct from the tap 3 and the tank 2.
Dans l'exemple représenté l'organe 6 de transfert peut être un second robinet et/ou un organe de conditionnement (assurant le remplissage et/ou le soutirage de fluide dans le réservoir 2 via le premier robinet 3).  In the example shown the transfer member 6 may be a second valve and / or a conditioning member (ensuring the filling and / or withdrawal of fluid in the tank 2 via the first valve 3).
Le second robinet 6 comprend un circuit interne 1 1 de transfert de fluide sous pression, comportant par exemple au mois l'un parmi : un clapet 21 d'isolation, un détendeur de pression, un régulateur de débit, une soupape de sécurité, un filtre...  The second valve 6 comprises an internal circuit 1 1 for transferring fluid under pressure, comprising for example at least one of: an isolation valve 21, a pressure regulator, a flow regulator, a safety valve, a filtered...
Le second robinet 6 et le premier robinet 3 comprennent des organes 7, 8 d'accrochage mécaniques respectifs formant un système de connexion rapide amovible du second robinet 6 sur le premier robinet 3.  The second valve 6 and the first valve 3 comprise respective mechanical fastening members 7, 8 forming a removable quick connection system of the second valve 6 on the first valve 3.
En position raccordée du second robinet 6 sur le premier robinet 3, le circuit interne 1 1 de l'organe 6 de transfert est relié fluidiquement (et de façon étanche via un système de joints(s)) au circuit 4 interne du premier robinet 3 (cf. figures 2, 3, 5 et 6).  In the connected position of the second valve 6 on the first valve 3, the internal circuit 1 1 of the transfer member 6 is fluidly connected (and sealed via a seal system (s)) to the internal circuit 4 of the first valve 3 (see Figures 2, 3, 5 and 6).
Le dispositif comprend une butée 9 sensible à la pression dans l'un au moins des circuits internes 4, 1 1 pour bloquer les organes 7, 8 d'accrochage en position connectée et empêcher leur séparation mécanique (déconnexion) lorsque ladite pression est supérieure à un seuil déterminé.  The device comprises a stop 9 responsive to the pressure in at least one of the internal circuits 4, 1 1 to block the hooking members 7, 8 in the connected position and prevent their mechanical separation (disconnection) when said pressure is greater than a determined threshold.
Selon une caractéristique avantageuse, la butée 9 est mobile entre une première position de non-blocage des organes 7, 8 d'accrochage pour permettre leur déconnexion et une seconde position de blocage des organes 7, 8 d'accrochage pour empêcher leur déconnexion. De plus, organe 12 de rappel tel qu'un ressort sollicite la butée 9 vers sa première position. According to an advantageous characteristic, the stop 9 is movable between a first non-locking position of the hooking members 7, 8 to allow them to be disconnected and a second locking position of the members 7, 8 snap to prevent disconnection. In addition, the return member 12 such as a spring biases the stop 9 to its first position.
De cette façon, en situation sans danger (pas de pression au sein du ou des circuits 4, 1 1 internes), la butée 9 n'entrave pas la libre connexion et déconnexion mécanique des deux robinets 3, 6.  In this way, in a safe situation (no pressure within the circuit or circuits 4, 1 1 internal), the stop 9 does not interfere with the free connection and mechanical disconnection of the two valves 3, 6.
Comme illustré schématiquement aux figures 1 à 3 et représenté aux figures 4 à 6, la butée 9 peut comprendre un pion mobile en translation entre ses première (cf. figures 1 , 2, 4 et 5) et seconde positions (cf. figures 3 et 6).  As illustrated schematically in FIGS. 1 to 3 and represented in FIGS. 4 to 6, the stop 9 may comprise a pin movable in translation between its first (see FIGS. 1, 2, 4 and 5) and second positions (see FIGS. 6).
La butée 9 peut notamment comprendre un pion mobile dans un logement 13 (du second robinet 6) entre les première et seconde positions. Ledit logement 13 comprend par exemple une première extrémité débouchant ou en liaison fluidique avec l'un au moins des circuits internes 4, 1 1 (cf. figures 4 à 6).  The stop 9 may in particular comprise a pin movable in a housing 13 (the second valve 6) between the first and second positions. Said housing 13 comprises for example a first end opening or in fluid connection with at least one of the internal circuits 4, 1 1 (see Figures 4 to 6).
Comme illustré aux figures 4 à 6, le second robinet 6 peut comporter un joint 14 d'étanchéité interposé entre la première extrémité du logement 13 et la butée 9 pour empêcher la communication fluidique entre le circuit interne 1 1 et une seconde extrémité du logement 13.  As illustrated in FIGS. 4 to 6, the second valve 6 may comprise a seal 14 interposed between the first end of the housing 13 and the stop 9 to prevent fluid communication between the internal circuit 11 and a second end of the housing 13. .
La seconde extrémité du logement 13 abrite une extrémité de la butée 9 destinée à former un arrêtoir de blocage mécanique pour les organes 7, 8 d'accrochage lorsque ladite butée 9 est dans sa seconde position. Par exemple, la seconde extrémité de la butée 9 fait saillie hors du logement dans sa seconde position (cf. figure 6).  The second end of the housing 13 houses one end of the stop 9 intended to form a mechanical locking stop for the members 7, 8 hooking when said stop 9 is in its second position. For example, the second end of the stop 9 protrudes out of the housing in its second position (see Figure 6).
Comme illustré, de préférence le second robinet 6 comprend un organe 10 de verrouillage mécanique d'au moins un des organes 7, 8 d'accrochage.  As illustrated, preferably the second valve 6 comprises a member 10 for mechanical locking of at least one of the members 7, 8 hooking.
L'organe 10 de verrouillage comprend par exemple manchon tubulaire mobile en translation selon un axe longitudinal A parallèle à ses génératrices sur le corps du second robinet 6. La butée 13 est notamment avantageusement mobile à l'intérieur du manchon, transversalement par rapport à l'axe longitudinal A (cf. figure 4).  The locking member 10 comprises, for example tubular sleeve movable in translation along a longitudinal axis A parallel to its generatrices on the body of the second valve 6. The stop 13 is particularly advantageously movable inside the sleeve, transversely relative to the longitudinal axis A (see Figure 4).
Cet organe 10 de verrouillage est mobile et actionnable manuellement entre une position active bloquant le déplacement relatif des organes 7, 8 d'accrochage (cf. figures 5 et 6) pour empêcher la désolidarisation du second robinet 6 par rapport au premier robinet 3 et une position inactive (lorsque le manchon 10 est déplacé vers la droite aux figures 4 à 6, dans le sens de son éloignement du premier robinet 3) autorisant le déplacement relatif des organes 7, 8 d'accrochage pour permettre la désolidarisation du second robinet 6 par rapport au premier robinet 3. This locking member 10 is movable and manually operable between an active position blocking the relative movement of the hooking members 7, 8 (see FIGS. 5 and 6) to prevent the second valve 6 from being detached from the first valve 3 and inactive position (when the sleeve 10 is moved to the right in Figures 4 to 6, in the direction of its distance from the first valve 3) allowing the relative movement of the hooking members 7, 8 to allow the second valve 6 to be separated from the first valve 3.
Dans sa première position, la butée 9 n'interfère pas avec l'organe 10 de verrouillage (cf. figure 4 ou 5). Dans sa seconde position, la butée 9 bloque mécaniquement l'organe 10 de verrouillage et empêche son déplacement de sa position active vers sa position inactive.  In its first position, the stop 9 does not interfere with the locking member 10 (see Figure 4 or 5). In its second position, the stop 9 mechanically locks the locking member 10 and prevents its displacement from its active position to its inactive position.
Plus précisément, lorsque le circuit 1 1 interne du second robinet 6 est sous pression (transfert de fluide depuis ou vers le premier robinet), la pression dans le circuit exerce un effort sur la butée 9 mobile pour la déplacer vers sa seconde position. Lorsque cette pression excède un seuil déterminé, cette force surpasse l'effort du ressort 12 et la butée 9 est déplacée de façon à se placer sur le trajet du manchon 10 (par exemple en saillie hors du passage 13).  More specifically, when the internal circuit 1 1 of the second valve 6 is under pressure (transfer of fluid from or to the first valve), the pressure in the circuit exerts a force on the movable stop 9 to move it to its second position. When this pressure exceeds a determined threshold, this force surpasses the force of the spring 12 and the stop 9 is moved so as to be in the path of the sleeve 10 (for example projecting out of the passage 13).
Malgré l'effort manuel de l'utilisateur, le manchon 10 de verrouillage reste alors dans sa position dans laquelle il bloque et rend impossible la déconnexion des organes 7, 8 d'accrochage. Ainsi, la butée permet de bloquer ou non les organes 7, 8 d'accrochage de façon indirecte (via le manchon 10). Bien entendu, en variante il est possible d'imaginer que la butée 9 mobile verrouille directement mécaniquement un des organes 7, 8 d'accrochage.  Despite the manual effort of the user, the locking sleeve 10 then remains in its position in which it blocks and makes impossible the disconnection of the bodies 7, 8 of attachment. Thus, the abutment makes it possible to block or not the members 7, 8 for hooking indirectly (via the sleeve 10). Of course, alternatively it is possible to imagine that the movable stop 9 locks directly mechanically one of the members 7, 8 hooking.
Comme illustré aux figures 4 à 6, le circuit interne 1 1 du second robinet 6 peut comprendre un axe 15 mobile en translation et formant un pousse-clapet destiné à ouvrir par actionnement mécanique le ou les clapets 20; 5 du premier robinet 3.  As illustrated in FIGS. 4 to 6, the internal circuit 1 1 of the second valve 6 can comprise an axle 15 that can be moved in translation and that forms a valve push-piece intended to open by mechanical actuation the valve or valves 20; 5 of the first tap 3.
Le pousse-clapet 15 est par exemple mobile en translation selon son axe de symétrie longitudinale A (de préférence confondu avec un axe longitudinal central du second robinet 6).  The poppet valve 15 is for example movable in translation along its longitudinal axis of symmetry A (preferably coincides with a central longitudinal axis of the second valve 6).
Le pousse-clapet 15 est par exemple déplacé manuellement ou automatiquement via un levier et/ou une commande à distance. Le pousse-clapet 15 peut pousser le clapet 20 pare-poussière qui pousse alors à son tour le clapet 4 d'isolation hors de son siège.  The valve push-button 15 is for example manually or automatically moved via a lever and / or a remote control. The valve push-piece 15 can push the damper 20 which then pushes the isolation valve 4 in its turn out of its seat.
De préférence, et comme illustré, la première extrémité du logement 13 de la butée 9 débouche dans une portion du circuit interne 1 1 de transfert du second robinet 6 comprenant l'axe 15 mobile. Selon une alternative possible, le déplacement de la butée 9 vers sa seconde position (ou première position) est couplé à la position du pousse-clapet 15 (via un couplage mécanique ou automatique par exemple). Par exemple, lorsque le pousse-clapet 15 est dans une position correspondant à une ouverture de vanne (en saillie), la butée 9 est déplacée automatiquement vers sa seconde position de verrouillage. Preferably, and as illustrated, the first end of the housing 13 of the abutment 9 opens into a portion of the internal circuit 1 1 transfer of the second valve 6 comprising the axis 15 movable. According to a possible alternative, the displacement of the stop 9 to its second position (or first position) is coupled to the position of the valve push-button 15 (via a mechanical or automatic coupling for example). For example, when the poppet valve 15 is in a position corresponding to a valve opening (projecting), the stopper 9 is automatically moved to its second locking position.
Dans les exemples non limitatifs représentés aux figures, le robinet 3 comprend une extrémité de raccordement de forme générale cylindrique.  In the non-limiting examples shown in the figures, the valve 3 comprises a connection end of generally cylindrical shape.
De plus, les organes 7, 8 d'accrochage comprennent d'une part au moins une rainure et/ou au moins une nervure 8 formée sur la surface extérieure de l'extrémité de raccordement du robinet 3 et, d'autre part, au moins un élément 7 d'accrochage monté mobile sur le second robinet 6 entre une position dite « écartée » pour permettre l'introduction de l'extrémité de raccordement du robinet 3 dans un espace central du second robinet 6 et une position dite « rapprochée » pour permettre l'accrochage du au moins un élément 7 d'accrochage sur la face extérieure de l'extrémité de raccordement du premier robinet 3.  In addition, the fastening members 7, 8 comprise on the one hand at least one groove and / or at least one rib 8 formed on the outer surface of the connecting end of the valve 3 and, on the other hand, on the less a hooking element 7 mounted to move on the second valve 6 between a position called "spaced" to allow the introduction of the connecting end of the valve 3 in a central space of the second valve 6 and a position called "close" to allow the hooking of the at least one attachment element 7 on the outer face of the connecting end of the first valve 3.
Dans l'exemple des figures 4 à 6, le au moins un élément 7 d'accrochage comprend un système de griffes 7 mobile.  In the example of FIGS. 4 to 6, the at least one fastening element 7 comprises a mobile claw system 7.
Les griffes 7 sont mobiles sur le second robinet 6 autour d'un espace central destiné à accueillir l'extrémité de raccordement du robinet 3. La face interne des griffes 7 située en vis-à-vis de l'espace central est munie de reliefs 12 et/ou de creux 2 complémentaires de la surface extérieure du premier robinet 3.  The claws 7 are movable on the second valve 6 around a central space intended to accommodate the connecting end of the valve 3. The inner face of the claws 7 located vis-à-vis the central space is provided with reliefs 12 and / or complementary recesses 2 of the outer surface of the first valve 3.
Les griffes 7 sont mobile transversalement par rapport à l'espace central. The claws 7 are movable transversely with respect to the central space.
Le manchon 10 de verrouillage est monté sur le second robinet 6 et est mobile rapport aux griffes 7 d'accrochage entre sa position active bloquant les griffes 7 en position rapprochée (figure 5 et 6) et sa position inactive autorisant le déplacement (écartement) des griffes 7 vers la position écartée. The locking sleeve 10 is mounted on the second valve 6 and is movable relative to the gripping claws 7 between its active position blocking the claws 7 in the close position (Figure 5 and 6) and its inactive position allowing the displacement (spacing) of claws 7 to the spread position.
Le manchon 10 de verrouillage est de préférence sollicité par défaut vers sa position active par un organe 16 de rappel tel qu'un ressort (cf. figures 4 à 6).  The locking sleeve 10 is preferably biased towards its active position by a return member 16 such as a spring (see Figures 4 to 6).
De même, lorsque les griffes 7 sont en position écartée, une butée 17 portée par les griffes 7 peut empêcher le passage du manchon de 10 de verrouillage de la position inactive vers la position active. En revanche, lorsque les griffes 7 sont en position rapprochée, le passage du manchon 10 de verrouillage de la position inactive vers la position active n'est pas entravé par la butée 17. Similarly, when the claws 7 are in the spaced apart position, a stop 17 carried by the claws 7 can prevent the passage of the locking sleeve 10 from the inactive position to the active position. On the other hand, when 7 claws are in the close position, the passage of the locking sleeve 10 from the inactive position to the active position is not obstructed by the stop 17.
Le second robinet 6 peut comprendre en outre un organe 18 mobile d'écartement sélectif des griffes 7. L'organe 18 d'écartement est mobile entre une position dite « de travail » empêchant le déplacement des griffes 7 de la position écartée vers la position rapprochée (figure 4) et une position dite « de repos » autorisant le déplacement des griffes 7 de la position écartée vers la position rapprochée (figures 5 et 6). L'organe (18) d'écartement est de préférence sollicité vers sa position de travail par un organe 19 de rappel tel qu'un ressort et peut être poussé vers sa position de repos par l'extrémité du premier robinet 3 lors de la connexion avec le second robinet 6.  The second valve 6 may further comprise a movable member 18 for spacing the claws 7. The spacer 18 is movable between a so-called "working" position preventing the displacement of the claws 7 from the spread position to the position close (Figure 4) and a so-called "rest" position allowing the movement of the claws 7 from the spread position to the close position (Figures 5 and 6). The spacer member (18) is preferably biased towards its working position by a return member 19 such as a spring and can be pushed towards its rest position by the end of the first valve 3 when connected. with the second tap 6.
Bien entendu, le système de connexion rapide à griffes peut être remplacé par tout autre système équivalent approprié, par exemple un système de bille(s) ou pion(s) rétractable(s) disposées sur le second robinet 6 venant de s'encliqueter sur le premier robinet 3.  Of course, the quick claw connection system can be replaced by any other appropriate equivalent system, for example a ball system (s) or pin (s) retractable (s) arranged on the second valve 6 just snapped on the first tap 3.
Ainsi, tout en étant de structure simple et peu coûteuse, l'invention permet de sécuriser la connexion de modules de transfert de fluide sous pression sans augmenter leur encombrement et sans nuire à leur ergonomie.  Thus, while being simple and inexpensive structure, the invention makes it possible to secure the connection of pressurized fluid transfer modules without increasing their size and without harming their ergonomics.
