- the poppet valve 15 comprises a tubular portion provided with a peripheral seals system (s) sealing the end of the internal circuit 4 of the first valve 3 and a part movable in translation in the tubular portion for actuating the valve or valves. That is to say that the fluid can pass via the inside of the tubular portion of the valve push-piece 15.
- the transfer member 6 and the first valve 3 comprises a mechanical locking member 10 of at least one of the members 7, 8 hooking.
- the locking member 10 is movable and manually operable between an active position blocking the relative movement of the hooking members 7, 8 to prevent the disengagement of the transfer member 6 from the first valve 3 and an inactive position allowing the relative movement of the fastening members 7, 8 to allow the disengagement of the transfer member 6 with respect to the first valve 3.
- At least a portion of the locking member 10 is housed inside the protective volume defined by the cap 20.
- the locking member is at least partially protected by the cap when the transfer member is connected to the first valve 3.
- the locking member 10 remains however accessible for a user in and / or outside the cap 20.
- the end of the transfer member 6 connectable on the second end of the first valve 3 has a generally tubular shape, so that the transfer member 6 and the second end of the first valve 3 form respectively female and male elements of a removable quick connection system.
- the transfer member 6 in the connected position of the transfer member 6 on the first valve 3, at least a portion of the transfer member 6 is housed in the cap 20 through the opening 21 and around the second end of the first valve 3.
- the edge defining the opening of the cap 20 is preferably spaced from the end of the transfer member 6 by a distance for example between 1mm and 5cm, for example between 1mm and 5mm.

- at least part of the fastening zone mechanical 7, 8 between the transfer member 6 and the second end of the first valve 3 is also housed in the protective volume 2 of the cap 20.
- the locking member 10 in the connected position of the transfer member 6 on the first valve 3, at least a portion of the locking member 10 can be located between the second end of the first valve 3 and the cap 20. That is to say that locally, the cap 20 is disposed around the locking member 10, itself arranged around the body of the transfer member 6, itself arranged around the body of the first tap 3 (cf. figure 4 ).
- the locking member 10 is disposed between the second end of the first valve 3 and the edge defining the opening of the cap 20 That is, the locking member 10 is manually accessible at the opening of the cap 20.
- the displacement could be in the opposite direction.
- the locking member 10 in the connected position of the transfer member 6 on the first valve 3, when it moves from its inactive position to its active position, the locking member 10 preferably moves the locking member 10 at least part towards the inside of the protective volume delimited by the cap 20.
- the locking member 10 in the connected position of the transfer member 6 on the first valve 3, during its displacement from its active position to its inactive position, the locking member 10 is preferably displaced at least partly to the outside of the protection volume delimited by the cap 20. In a variant, this displacement could be in the opposite direction. That is to say that, preferably, the displacement of the member 10 to unlock the mechanical connection between the first valve 3 and the transfer member 6 tends to at least partly release the locking member 10 the volume of the hat 20.
- the locking member 10 In the connected position, at least in the active position or in the inactive position, the locking member 10 has a position housed in the protective volume delimited by the cap and a position situated outside the protective volume delimited by the cap.
- the locking member 10 in the connected position of the transfer member 6 on the first valve 3, and whatever its position between active and inactive positions, has a portion housed in the protective volume defined by the cap 20 and optionally a portion located outside the protective volume defined by the cap 20. This allows both to ensure mechanical protection of the mechanism while making easily accessible the locking member 10.
- the member 10 completely out of the protective volume of the cap 20 when it is disposed in its inactive position.
- the locking member 10 comprises a tubular sleeve movable in translation on the body of the transfer member 6 along a longitudinal axis. More precisely, in the position connected to the first valve, the locking sleeve 10 can be displaced in translation along (around) the central longitudinal axis A of the first valve 3.
- the sleeve 10 thus slides around the body of the transfer member 6 and thus around the second end of the first valve 3.
- 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 second end of the first valve 3 and, on the other hand, at least one attachment element 7 mounted movably on the transfer member 6.
- the geometries (dimensions, positions) of the fastening members 7, 8 are complementary and preferably exclusive to form a fastening system which prevents the connection of a third member that does not have the same geometrical characteristics.
- connection system includes a locking (i.e., mechanical latch) and a keying function (i.e., a male / female system that connect a specific geometry plug to a specific type of connection to avoid dangerous connections).
- a locking i.e., mechanical latch
- a keying function i.e., a male / female system that connect a specific geometry plug to a specific type of connection to avoid dangerous connections.
- the hooking member 7 is movable between a so-called “spaced” position to allow the insertion of the connection end of the valve 3 into the central space of the transfer member 6 and a so-called “close” position for allow the attachment of the at least one attachment element 7 on the outer face of the connecting end of the first valve 3.
- the at least one attachment element 7 comprises at least one mobile claw system 7.
- the claws 7 could be replaced by a system of balls or retractable pins (s) well known in the fast connection systems.
- the hooking element comprises at least one and preferably several claws 7 (two, three, four ...) movable arranged around a central space for receiving the connecting end of the tap 3.
- An inner face of claws 7 located opposite the central space is provided with reliefs and / or recesses complementary to the outer shape of the first valve 3.
- the claws 7 are movable transversely relative to the central space (cf. figures 3 and 4 ).
- the transfer member 6 can be threaded onto the second end of the first valve 3.
- a stop 17 formed on the claw (s) 7 can prevent the passage of the sleeve 10 locking the inactive position to the active position despite the effort of the spring 16.
- the transfer member 6 may comprise a movable member 18 for spacing the claws 7 apart.
- the spacer member 18 may be movable between a so-called “working” position preventing the claws 7 from moving from the position spread towards the close position (cf. figures 2 and 3 ) and a so-called “rest” position authorizing the displacement of the claws 7 from the spaced apart position to the close position ( figure 4 ).
- the spacer member 18 is preferably biased towards its working position by a return member 19.
- the claws 7 are biased toward their close position by the locking sleeve 10.
- the approximation of the claws 7 is possible when the latter are vis-à-vis their conjugate form 8 on the first valve 3.
- the sleeve 10 is thus sinking into the cap 20 by covering and locking the claws 7 in their housing 8 on the first valve 3.
- the attachment is performed semi-automatically. The beginning of the mechanical connection is performed manually by the operator and the final latching and locking is obtained by the return members 16 which urge the locking sleeve 10 in its locking position of the connection between the members 7, 8 hooking.
- the user To disengage the transfer member 6, the user must move the locking sleeve 10 to the inactive position (upwards in the figures in the direction of its exit from the hat) to discover the claws 7 and allow them to deviate their attachment zone 8 of the first valve 3.
- the structure and operation of the device provides high reliability and security against shocks or mishandling.
- the invention also relates to a method of connecting the transfer member 6 to the first valve 3 and / or respectively a method of separating the transfer member from the first valve 3 in which the locking member 10 is actuated and moved from its inactive position to its active position, respectively from its active position to its inactive position.
- the locking member 10 can be arranged or held in its inactive position to allow the cooperation of the bodies 7, 8 of attachment of the organ 6 tranfer and the first valve 3 (for example by snapping and / or snapping).
- the locking member is moved automatically and / or manually to its active position.
- the locking member 10 is moved from its inactive position to its active position (manually for example).
- the hooking members 7, 8 can be moved relatively to allow the separation of the two sets.

Le circuit 4 interne débouche par exemple au niveau de deux extrémités du corps du premier robinet 3.The
Le dispositif comprend de plus un chapeau 20 de protection du premier 3 robinet. Le chapeau 20 est monté (fixé rigidement) sur le réservoir 2, par exemple au niveau d'un col du réservoir 2 (par exemple autour de la portion du réservoir 20 délimitant l'orifice accueillant le premier robinet 3). Le chapeau 20 délimite une enceinte de protection autour du premier robinet 3 munie d'une ouverture 21 d'accès à la seconde extrémité du premier robinet 3.The device further comprises a

L'organe 10 de verrouillage reste cependant accessible pour un utilisateur dans et/ou à l'extérieur du chapeau 20.The locking
Ceci permet de protéger le verrouillage de la fixation mécanique de l'organe 6 de transfert sur le premier robinet 3 en cas de choc extérieur et limite également les risques de mauvaises manipulations par un utilisateur.This makes it possible to protect the locking of the mechanical fastener of the
Comme illustré dans l'exemple des figures, de préférence l'extrémité de l'organe 6 de transfert raccordable sur la seconde extrémité du premier robinet 3 a une forme générale tubulaire, de sorte que l'organe 6 de transfert et la seconde extrémité du premier robinet 3 forment des éléments respectivement femelle et mâle d'un système de connexion rapide amovible.As illustrated in the example of the figures, preferably the end of the
De plus, de préférence, en position raccordée de l'organe 6 de transfert sur le premier robinet 3, au moins une partie de l'organe 6 de transfert est logé dans le chapeau 20 au travers de l'ouverture 21 et autour de la seconde extrémité du premier robinet 3.

De cette façon, une zone au moins où l'organe 6 de transfert est fixé sur le premier robinet 3 est également logée (abritée) dans le volume de protection du chapeau 20. De préférence, au moins une partie de la zone d'accrochage mécanique 7, 8 entre l'organe 6 de transfert et la seconde extrémité du premier robinet 3 est également abritée dans le volume 2 de protection du chapeau 20.In this way, at least one zone where the
Ceci participe également la sécurité du dispositif en protégeant les organes 7, 8 d'accrochage de l'organe 6 de transfert sur le premier robinet 3.This also contributes to the safety of the device by protecting the
Comme illustré dans l'exemple des figures, en position raccordée de l'organe 6 de transfert sur le premier robinet 3, au moins une partie de l'organe 10 de verrouillage peut être situé entre la seconde extrémité du premier robinet 3 et le chapeau 20. C'est-à-dire que localement, le chapeau 20 est disposé autour de l'organe 10 de verrouillage, lui-même disposé autour du corps de l'organe 6 de transfert, lui-même disposé autour du corps du premier robinet 3 (cf.
De plus, en position raccordée de l'organe 6 de transfert sur le premier robinet 3, au moins une partie de l'organe 10 de verrouillage est disposée entre la seconde extrémité du premier robinet 3 et la bordure délimitant l'ouverture le chapeau 20. C'est-à-dire que l'organe 10 de verrouillage est accessible manuellement au niveau de l'ouverture du chapeau 20. En variante le déplacement pourrait être en sens inverse.In addition, in the connected position of the
De plus, en position raccordée de l'organe 6 de transfert sur le premier robinet 3, lors de son déplacement de sa position inactive vers sa position active l'organe 10 de verrouillage l'organe 10 de verrouillage se déplace de préférence au moins en partie vers l'intérieur du volume protection délimité par le chapeau 20.Moreover, in the connected position of the
Outre son aspect ergonomique, ce mouvement renforce la protection du verrouillage.In addition to its ergonomic appearance, this movement enhances lock protection.
De plus, en position raccordée de l'organe 6 de transfert sur le premier robinet 3, lors de son déplacement de sa position active vers sa position inactive, l'organe 10 de verrouillage l'organe 10 de verrouillage est déplacé de préférence au moins en partie vers l'extérieur du volume protection délimité par le chapeau 20. En variante, ce déplacement pourrait être en sens inverse. C'est-à-dire que, de préférence, le déplacement de l'organe 10 pour déverrouiller la liaison mécanique entre le premier robinet 3 et l'organe 6 de transfert tend à faire sortir au moins en partie l'organe 10 de verrouillage du volume du chapeau 20.In addition, in the connected position of the
En position raccordée, au moins en position active ou en position inactive, l'organe 10 de verrouillage possède une position logée dans le volume de protection délimité par le chapeau et une position située en dehors du volume de protection délimité par le chapeau.In the connected position, at least in the active position or in the inactive position, the locking

Ceci permet à la fois de garantir une protection mécanique du mécanisme tout en rendant facilement accessible l'organe 10 de verrouillage. Bien entendu, il est possible de prévoir une variante dans laquelle l'organe 10 sort complètement du volume de protection du chapeau 20 lorsqu'il est disposé dans sa position inactive.Also preferably, in the connected position of the
Dans l'exemple de réalisation non limitatif des figures, l'organe 10 de verrouillage comprend un manchon tubulaire mobile en translation sur le corps de l'organe 6 de transfert selon un axe longitudinal. Plus précisément, en position raccordée sur le premier robinet, le manchon 10 de verrouillage peut être déplacé en translation selon (autour) de l'axe longitudinal central A du premier robinet 3.In the non-limiting embodiment of the figures, the locking
Le manchon 10 coulisse ainsi autour du corps de l'organe 6 de transfert et donc autour de la second extrémité du premier robinet 3.The
De plus, dans l'exemple représenté aux figures 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 la seconde extrémité du premier robinet 3 et, d'autre part, au moins un élément 7 d'accrochage monté mobile sur l'organe 6 de transfert. Les géométries (dimensions, positions) des organes 7, 8 d'accrochage sont complémentaires et de préférence exclusives pour former un système d'accrochage qui empêche la connexion d'un organe tiers n'ayant pas les mêmes caractéristiques géométriques.In addition, in the example shown in the figures, the
C'est-à-dire que le système de connexion comprend une fonction de verrouillage (c'est-à-dire d'accrochage mécanique) et un détrompeur (c'est-à-dire un système mâle/femelle qui ne permet de connecter qu'une prise de géométrie déterminée sur un raccord de type déterminé pour éviter des connexions dangereuses).That is, the connection system includes a locking (i.e., mechanical latch) and a keying function (i.e., a male / female system that connect a specific geometry plug to a specific type of connection to avoid dangerous connections).
L'organe 7 d'accrochage est mobile entre une position dite « écartée » pour permettre l'introduction de l'extrémité de raccordement du robinet 3 dans l'espace central de l'organe 6 de transfert 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.The hooking
Dans l'exemple représenté aux
L'élément d'accrochage comprend au moins une et de préférence plusieurs griffes 7 (deux, trois, quatre...) mobiles disposées autour d'un espace central destiné à accueillir l'extrémité de raccordement du robinet 3. Une face interne de des griffes 7 située en vis-à-vis de l'espace central est munie de reliefs et/ou de creux complémentaires de la forme extérieur du premier robinet 3. Les griffes 7 sont mobiles transversalement par rapport à l'espace central (cf.
Comme visible à la
L'organe 6 de transfert peut comporter un organe 18 mobile d'écartement sélectif des griffes 7. L'organe 18 d'écartement peut être mobile entre une position dite « de travail » empêchant le déplacement des griffes 7 de la position écartée vers la position rapprochée (cf.
Par exemple, en enfonçant l'organe 6 de transfert sur le premier robinet, le blocage des griffes 7 en position écarté est supprimé (l'organe 18 d'écartement est repoussé).For example, by pressing the
Les griffes 7 sont sollicitées vers leur position rapprochée par le manchon 10 de verrouillage. Le rapprochement des griffes 7 est possible lorsque ces dernière sont en vis-à-vis de leur forme conjuguée 8 sur le premier robinet 3. En se rabattant vers l'intérieur, les griffes 7 ne font plus obstacle au déplacement du manchon 10 de verrouillage en position active. Le manchon 10 vient donc s'enfoncer dans le chapeau 20 en recouvrant et en verrouillant les griffes 7 dans leur logement 8 sur le premier robinet 3. L'accrochage s'effectue de façon semi-automatique. Le début de la connexion mécanique est réalisée manuellement par l'opérateur et l'encliquetage final et le verrouillage est obtenu par les organes de rappel 16 qui sollicitent le manchon 10 de verrouillage dans sa position de verrouillage de la connexion entre les organes 7, 8 d'accrochage.The
Dans cette position active le manchon 10 vient enserrer les griffes 7 en position rapprochée. C'est-à-dire que le manchon 10 forme une butée mécanique bloquant l'écartement des griffes 7.In this position activates the
Pour désolidariser l'organe 6 de transfert, l'utilisateur doit déplacer le manchon 10 de verrouillage vers la position inactive (vers le haut sur les figures en direction de sa sortie du chapeau) pour découvrir les griffes 7 et leur permettre de s'écarter de leur zone d'accrochage 8 du premier robinet 3.To disengage the
La structure et le fonctionnement du dispositif confère une grande fiabilité et sécurité contre les chocs ou mauvaises manipulations.The structure and operation of the device provides high reliability and security against shocks or mishandling.
L'invention concerne également un procédé de raccordement de l'organe 6 de transfert sur le premier robinet 3 et/ou respectivement un procédé de séparation de l'organe de transfert du premier robinet 3 dans lequel l'organe 10 de verrouillage est actionné et déplacé de sa position inactive vers sa position active, respectivement de sa position active vers sa position inactive.
