Le robinet 1 pour fluide sous pression représenté schématiquement peut être un robinet avec ou sans détendeur de pression intégré.The valve 1 for pressurized fluid represented schematically can be a valve with or without an integrated pressure regulator.

Le robinet 1 comprend un corps 2 abritant un circuit 3 de fluide ayant une extrémité 4 amont destinée à être mise en relation avec une réserve de fluide sous pression (par exemple gaz sous pression) et une extrémité 5 aval destinée à être mise en relation avec un appareil utilisateur (par exemple au niveau d'un raccord de sortie).The valve 1 comprises a body 2 housing a fluid circuit 3 having an upstream end 4 intended to be connected with a reserve of pressurized fluid (for example pressurized gas) and a downstream end 5 intended to be connected with a user device (for example at an outlet connection).

De préférence le corps 2 est une entité fonctionnelle unique non dissociable notamment lorsque le robinet est en configuration d'utilisation. Le robinet 1 peut notamment être raccordé à une bouteille 20 ou un ensemble de bouteilles de fluide sous pression.Preferably the body 2 is a single functional entity that cannot be dissociated, in particular when the valve is in the configuration for use. The valve 1 can in particular be connected to a bottle 20 or a set of bottles of pressurized fluid.

Le circuit 3 peut comprendre classiquement une vanne 6 de contrôle du débit dans le circuit 3. La vanne 6 peut être un clapet d'isolement. Comme illustré schématiquement un régulateur 12 de débit ou de pression peut également être prévu dans le circuit 3.Circuit 3 can conventionally comprise a valve 6 for controlling the flow rate in circuit 3. Valve 6 can be an isolation valve. As schematically illustrated, a flow or pressure regulator 12 can also be provided in circuit 3.

Au moins la vanne 6 peut être pilotée par un organe 7 d'actionnement mobile (manuel et/ou piloté à distance) pour commander l'ouverture ou la fermeture de cette dernière. Dans l'exemple représente, cet organe 7 d'actionnement est un levier pivotant sur le corps 2. Bien entendu, cet organe 7 d'actionnement pourrait être un volant rotatif et/ou un bouton poussoir par exemple.At least the valve 6 can be controlled by a movable actuation member 7 (manual and/or remotely controlled) to control the opening or closing of the latter. In the example shown, this actuation member 7 is a pivoting lever on the body 2. Of course, this member 7 actuation could be a rotary wheel and / or a push button for example.

Le robinet 1 comprend une extrémité inférieure de montage munie d'organes 11 d'accrochage mobiles destinés à coopérer avec des organes d'accrochage complémentaires pour former un système de connexion rapide du robinet 1 sur une source de gaz ou un circuit.The valve 1 comprises a lower mounting end provided with movable attachment members 11 intended to cooperate with complementary attachment members to form a quick connection system of the valve 1 on a gas source or a circuit.

Les organes 11 mobiles d'accrochage comprennent par exemple des éléments mobiles (billes et/ou griffes par exemple) qui viennent s'accrocher sur des logements conjugués.The movable attachment members 11 include, for example, movable elements (balls and/or claws, for example) which are attached to mating housings.

Le robinet 1 comporte un organe 10 de verrouillage et de déverrouillage monté mobile autour du corps 2 du robinet 1 entre une première position et une seconde position par rapport au corps 2. Dans sa première position l'organe 10 de verrouillage ne bloque pas le déplacement des organe(s) 11 d'accrochage. Dans cette position, la connexion rapide n'est pas verrouillée et le robinet 1 peut être séparé mécaniquement de son support et peut notamment être raccordé à un support conjugué. Dans sa seconde position, l'organe 10 de verrouillage bloque le déplacement de(s) organes 11 d'accrochage. Dans cette position, la connexion mécanique est verrouillée et le robinet 1 ne peut pas être séparé mécaniquement de son support sans déplacer à nouveau l'organe 10 de verrouillage vers sa première position (il s'agit d'une mesure de sécurité de la liaison mécanique permettant un transfert de fluide à haute pression depuis ou vers le robinet 1).The valve 1 comprises a locking and unlocking member 10 mounted to move around the body 2 of the valve 1 between a first position and a second position relative to the body 2. In its first position the locking member 10 does not block the movement member (s) 11 for attachment. In this position, the quick connection is not locked and the valve 1 can be mechanically separated from its support and can in particular be connected to a mating support. In its second position, the locking member 10 blocks the movement of the member(s) 11 for attachment. In this position, the mechanical connection is locked and the tap 1 cannot be mechanically separated from its support without again moving the locking member 10 towards its first position (this is a safety measure for the connection mechanism allowing a transfer of fluid at high pressure from or to the valve 1).

Par exemple, dans sa première position, l'organe 10 de verrouillage ne bloque pas le déplacement des organes 11 mobiles d'accrochage (connexion-déconnexion possible cf. [Fig. 1] avec par exemple écartement des organes 11 d'accrochage) tandis que dans sa seconde position, l'organe 10 de verrouillage 10 bloque le déplacement des organes 11 mobiles (déconnexion et éventuellement connexion impossibles, cf. [Fig. 2] par exemple écartement impossible).For example, in its first position, the locking member 10 does not block the movement of the mobile attachment members 11 (connection-disconnection possible cf. [ Fig. 1 ] with for example spacing of the attachment members 11) while in its second position, the locking member 10 blocks the movement of the movable members 11 (disconnection and possibly connection impossible, cf. [ Fig. 2 ] for example impossible spacing).

Par exemple, selon sa position relativement aux organes 11 d'accrochage, l'organe 10 de verrouillage forme ou non une butée pour le déplacement de ces derniers (pour leur écartement par exemple).For example, depending on its position relative to the attachment members 11, the locking member 10 may or may not form a stop for the movement of the latter (for their spacing, for example).

De préférence, l'organe 10 de verrouillage est mobile en translation verticalement (haut/bas) sur le corps 2 du robinet 1. Par exemple, l'organe 10 de verrouillage est sollicité vers sa seconde position (basse) par un organe 13 de rappel tel qu'un ressort par exemple). Lors du raccordement de l'extrémité inférieure de montage sur un support ayant des organes d'accrochage complémentaires, l'organe 10 de verrouillage est libéré (par exemple par poussée sur son extrémité inférieure) et se déplace automatiquement en position de verrouillage (seconde position).Preferably, the locking member 10 is movable in translation vertically (up/down) on the body 2 of the valve 1. For example, the locking member 10 is biased towards its second position (lower) by a member 13 of reminder such as a spring for example). When the lower end of the assembly is connected to a support having complementary attachment members, the locking member 10 is released (for example by pushing on its lower end) and moves automatically into the locking position (second position ).

Comme illustré, l'organe 10 de verrouillage peut comprendre une portion tubulaire disposée autour d'au moins une partie du corps 2 du robinet 1.As illustrated, the locking member 10 may comprise a tubular portion arranged around at least a part of the body 2 of the valve 1.

L'organe 10 de verrouillage comprend une première extrémité 101 inférieure destinée à bloquer les organe(s) 11 d'accrochage dans la seconde position, et une seconde extrémité 102 supérieure de préhension destinée à déplacer manuellement l'organe 10 de verrouillage dans sa première position.The locking member 10 comprises a first lower end 101 intended to block the attachment member(s) 11 in the second position, and a second upper gripping end 102 intended to manually move the locking member 10 into its first position.

Dans ce qui précède et suit on désigne par « supérieur » et inférieure » les positions relatives verticales des éléments lorsque le robinet est en position d'utilisation (monté verticalement sur l'extrémité supérieure d'un réservoir par exemple, par exemple selon un axe A vertical).In what precedes and follows, the term “upper” and lower” denotes the relative vertical positions of the elements when the valve is in the position of use (mounted vertically on the upper end of a tank for example, for example along an axis A-vertical).

Le robinet 1 comprend à une extrémité supérieure, une tête 8 fixe par rapport au corps 2. La tête 8 forme par exemple une saillie latérale en T verticalement à la façon d'un chapeau de champignon.The valve 1 comprises at an upper end, a head 8 fixed relative to the body 2. The head 8 forms for example a lateral T-shaped projection vertically like a mushroom cap.

Selon une particularité avantageuse, l'extrémité 102 de préhension est située dans un logement de la tête 8 et est mobile dans la tête 8 entre une position haute au moins partiellement escamotée dans la tête 8 lorsque l'organe 10 de verrouillage est dans sa première position (cf. [Fig. 1]) et une position basse faisant moins partiellement saillie en-dessous de la tête 8 lorsque l'organe 10 de verrouillage est dans sa seconde position (cf. [Fig. 2]).According to an advantageous feature, the gripping end 102 is located in a housing of the head 8 and is movable in the head 8 between a high position at least partially retracted in the head 8 when the locking member 10 is in its first location (see [ Fig. 1 ]) and a low position projecting less partially below the head 8 when the locking member 10 is in its second position (cf. [ Fig. 2 ]).

De cette façon, l'extrémité 102 de préhension peut être actionnée manuellement vers le haut (remontée par le bout des doigts tel que schématisé à la [Fig. 2]). Par exemple, ce déplacement de la seconde vers la première position est réalisé en pinçant avec la main le dessus de la tête 8 et le dessous de l'extrémité de préhension 102.In this way, the gripping end 102 can be manually actuated upwards (raised by the fingertips as shown schematically in [ Fig. 2 ]). For example, this movement from the second to the first position is achieved by pinching with the hand the top of the head 8 and the bottom of the grip end 102.

Comme illustré, l'extrémité 102 de préhension comprend de préférence deux parties situées respectivement à deux extrémité latérales opposées de la tête 8. C'est -à-dire de part et d'autre de l'axe A central orienté selon la direction inférieure/supérieure du robinet 1. Ainsi, la manipulation de l'organe 10 de verrouillage peut être réalisé à deux mains au niveau de ces deux côtés.As illustrated, the gripping end 102 preferably comprises two parts located respectively at two opposite lateral ends of the head 8. That is to say on either side of the central axis A oriented in the lower direction. / Upper valve 1. Thus, the manipulation of the locking member 10 can be performed with both hands at these two sides.

De préférence, le robinet 1 comporte une coque 9 extérieure rigide fixe disposée autour du corps 2 et autour d'au moins une partie de l'organe 10 de verrouillage à l'exception de l'extrémité 102 de préhension. Cette coque 9 est par exemple fixée par rapport au corps et cache l'essentiel de l'organe 10 de verrouillage et des orifices et mécanismes à l'exception de l'extrémité 102 de préhension et éventuellement de l'extrémité inférieure de l'organe 10 de verrouillage.Preferably, the valve 1 comprises a fixed rigid outer shell 9 arranged around the body 2 and around at least a part of the locking member 10 with the exception of the gripping end 102 . This shell 9 is for example fixed relative to the body and hides most of the locking member 10 and the orifices and mechanisms with the exception of the end 102 for gripping and possibly the lower end of the member. 10 locking.

Ceci protège le robinet 1 et notamment l'organe 10 de verrouillage et les mécanismes sur la périphérie du corps 2 du robinet. Ceci permet de protéger notamment contre l'intrusion de saletés, doigts ou autre dans des espaces creux.This protects the valve 1 and in particular the locking member 10 and the mechanisms on the periphery of the body 2 of the valve. This makes it possible to protect in particular against the intrusion of dirt, fingers or the like into hollow spaces.

La [Fig. 3] illustre un dispositif 100 de fourniture de fluide sous pression, notamment de gaz sous pression, comprenant un premier ensemble 20, 30, 1 1 1 fonctionnel comportant au moins une bouteille 20 de fluide sous pression reliée à un premier robinet 30 et munie d'un chapeau 111. Ce premier ensemble est prévu pour coopérer cas échéant avec un second robinet 1 tel que décrit ci-dessus.There [ Fig. 3 ] illustrates a device 100 for supplying pressurized fluid, in particular pressurized gas, comprising a first functional assembly 20, 30, 111 comprising at least one bottle 20 of pressurized fluid connected to a first valve 30 and provided with a cap 111. This first assembly is provided to cooperate if necessary with a second valve 1 as described above.

Le second robinet 1 forme une entité physique distincte du premier robinet 30. Le second robinet 1 tel que décrit précédemment est raccordable (mécaniquement et fluidiquement) au premier robinet 30. Le premier 30 robinet et le second 1 robinet possèdent ainsi des organes 7, 11 d'accrochages respectifs formant un système de connexion rapide male/femelle amovible du second robinet 1 sur le premier 30.The second tap 1 forms a separate physical entity from the first tap 30. The second tap 1 as described previously can be connected (mechanically and fluidically) to the first tap 30. The first tap 30 and the second tap 1 thus have members 7, 11 of respective attachments forming a removable male/female quick connection system of the second valve 1 on the first 30.

Le premier 30 robinet comprend un circuit 13 interne de fluide comportant par exemple au moins un clapet 40 d'isolation. En plus ou à la place de la vanne 6, le second robinet 1 peut comporter un organe 17 mobile (tel qu'un pousse-clapet) pour commander l'ouverture ou la fermeture du clapet 40 d'isolation du premier robinet 30. L'organe 17 mobile est par exemple commande par l'organe 7 d'actionnement (levier 7 ou équivalent). Lorsque les deux robinets 1, 30 sont raccordes une liaison fluidique peut être établie entre les circuits internes 13, 3 des deux robinets.The first valve 30 comprises an internal fluid circuit 13 comprising for example at least one isolation valve 40 . In addition to or instead of the valve 6, the second valve 1 may include a movable member 17 (such as a valve pusher) to control the opening or closing of the valve 40 isolating the first valve 30. The the movable member 17 is for example controlled by the actuating member 7 (lever 7 or equivalent). When the two taps 1, 30 are connected, a fluid connection can be established between the internal circuits 13, 3 of the two taps.

Lorsque le second robinet 1 est raccordé (monté) sur le premier 30 robinet (cf. [Fig. 1] et [Fig. 2]), l'organe 10 de verrouillage est déplacé vers le bas pour verrouiller la connexion rapide. Pour la séparation des deux robinets, l'utilisateur déplace l'organe 10 de verrouillage vers le haut comme décrit ci-dessus pour libérer les organes 11 d'accrochage.When the second tap 1 is connected (mounted) to the first tap 30 (cf. [ Fig. 1 ] and [ Fig. 2 ]), the locking member 10 is moved downwards to lock the quick connection. For the separation of the two taps, the user moves the locking member 10 upwards as described above to release the fastening members 11 .

Le déplacement de l'organe 10 de verrouillage entre sa première position (cf. [Fig. 1]) et sa seconde position par rapport au corps 2 (cf. [Fig. 2]) fait ressortir l'extrémité de préhension au bas de la tête 8.The movement of the locking member 10 between its first position (cf. [ Fig. 1 ]) and its second position relative to the body 2 (see [ Fig. 2 ]) brings out the grip end at the bottom of the head 8.

Cette saillie ou non de l'extrémité de préhension au bas de la tête 8, outre son ergonomie, renseigne visuellement l'utilisateur sur l'état de raccordement mécanique du robinet (verrouillage ou non).This projection or not of the gripping end at the bottom of the head 8, in addition to its ergonomics, visually informs the user about the mechanical connection state of the valve (locking or not).
