Description

La présente invention concerne les détendeurs de gaz respirable sous pression, du type comprenant une extrémité connectable à un corps de robinet d'amenée de gaz à pression haute, cette extrémité définissant un canal d'amenée de gaz sous pression, notamment de mélange de gaz respiratoire pour plongeur ou pompier / sauveteur.The present invention relates to pressurized breathable gas pressure regulators, of the type comprising an end connectable to a high pressure gas supply valve body, this end defining a pressurized gas supply channel, especially a gas mixture duct. respiratory for diver or firefighter / rescuer.

Ces types de détendeurs sont connectés et déconnectés à l'ensemble robinet / réservoir de gaz avant et après chaque utilisation. Dans le domaine de la plongée sous-marine, après chaque utilisation les détendeurs sont rincés dans de l'eau douce puis stockés à l'air libre.These types of regulators are connected and disconnected to the faucet / gas tank assembly before and after each use. In the field of scuba diving, after each use the regulators are rinsed in fresh water and stored in the open air.

Le document US 4396032 , qui est considéré comme étant l'état de la technique le plus proche, décrit un détendeur de gaz respirable, ayant les caractéristiques du préamble de la revendication 1.The document US 4396032 , which is considered to be the closest state of the art, describes a breathable gas expansion valve having the features of the preamble of claim 1.

Pour éviter l'introduction de corps étrangers (poussière, humidité, graisse, ...) dans le détendeur pendant son stockage et son rinçage éventuel, on a proposé d'adapter sur l'extrémité de connexion un élément d'obturation articulé, par exemple du type couvercle, actionnable manuellement. Cet actionnement manuel, outre qu'il complexifie et fragilise l'extrémité de connexion, et empêche la mise en place d'un opercule de protection, rend également complexe la procédure de connexion et ne garantit pas la pénétration de corps étrangers juste avant ou après la connexion / déconnexion avec l'ensemble robinet / bouteille.To prevent the introduction of foreign bodies (dust, moisture, grease, etc.) into the expander during its storage and possible rinsing, it has been proposed to adapt to the connection end a hinged closing element, for example example of the lid type, manually operable. This manual actuation, in addition to complicating and weakening the connection end, and preventing the establishment of a protective cover, also makes the connection procedure complex and does not guarantee the penetration of foreign bodies just before or after connection / disconnection with the faucet / bottle assembly.

La présente invention a pour objet de proposer un agencement simple, robuste et fiable permettant une obturation ou une ouverture automatique du canal d'amenée de gaz lors de la connexion au corps de robinet et convenant aussi bien pour les connexions de type dit « étrier » ou de type dit « DIN».The present invention aims to provide a simple, robust and reliable arrangement for closing or opening automatically the gas supply channel when connected to the valve body and suitable for both type of connection called "stirrup" or type called "DIN".

Pour ce faire, selon une caractéristique de l'invention, le canal d'amenée se termine dans un élément de clapet stationnaire coopérant avec un siège mobile sollicité par un moyen élastique dans une position d'obturation du canal d'amenée, et comprenant une face externe susceptible de coopérer en engagement avec une surface correspondante du corps du robinet pour repousser le siège mobile à l'encontre du moyen élastique vers une position d'ouverture lors de la connexion avec le corps de robinet.To do this, according to a characteristic of the invention, the feed channel terminates in a stationary valve member cooperating with a mobile seat biased by an elastic means in a closed position of the supply channel, and comprising a external face capable of cooperating in engagement with a corresponding surface of the valve body to push the movable seat against the resilient means to an open position upon connection with the valve body.

Selon d'autres caractéristiques de l'invention :

  • le siège mobile est annulaire et forme une arête de siège coopérant avec une surface arrière, typiquement tronconique, d'une partie de tête terminale de l'élément de clapet
  • la face externe du siège mobile est une face annulaire d'extrémité coopérant avec un épaulement formé dans le corps de robinet
  • l'extrémité du détendeur est vissée dans ou plaquée contre le corps de robinet par une vis d'étrier.
According to other features of the invention:
  • the movable seat is annular and forms a seat edge cooperating with a rear surface, typically frustoconical, of a terminal head portion of the valve member
  • the outer face of the movable seat is an annular end face cooperating with a shoulder formed in the valve body
  • the end of the expander is screwed into or pressed against the valve body by a caliper screw.

D'autres caractéristiques et avantages de l'invention ressortiront de la description suivante de modes de réalisation, donnés à titre indicatif mais nullement limitatif, faite en relation avec les dessins annexés, sur lesquels :

  • la figure 1 est une vue schématique en coupe d'un premier mode de réalisation selon l'invention pour une connexion du type dit « à étrier » ;

Dans la description qui va suivre et sur les dessins, les éléments identiques ou analogues portent les mêmes chiffres de référence, éventuellement indicés.In the following description and on the drawings, identical or similar elements bear the same reference numbers, possibly indexed.

Dans le mode de réalisation des figures 1 et 2, on reconnaît un bloc détendeur 1 incorporant un dispositif détendeur intégré à membrane 2 destiné à être connecté à un corps de robinet 3 via, dans le mode de connexion dit à « étrier », un étrier 4 solidaire du bloc 1 recevant le corps de robinet 3 et portant une vis de pression 5 destinée à plaquer le corps de robinet 3 en position de connexion contre le bloc détendeur 1. Ce dernier comporte au moins une sortie de gaz moyenne / basse pression 60 du gaz acheminé par le corps de robinet 3 vers le dispositif détendeur 2 via un canal d'amenée de gaz sous pression 6 débouchant vers l'extérieur de l'extrémité de connexion du bloc détendeur 1.In the embodiment of Figures 1 and 2 , there is recognized a regulator block 1 incorporating a membrane integrated expansion device 2 intended to be connected to a valve body 3 via, in the so-called "stirrup" connection mode, a stirrup 4 secured to the block 1 receiving the valve body 3 and carrying a pressure screw 5 for pressing the valve body 3 in the connection position against the expander block 1. The latter comprises at least one medium / low pressure gas outlet 60 of the gas conveyed by the valve body 3 to the expander device 2 via a pressurized gas supply channel 6 opening towards the outside of the connection end of the expander block 1.

Comme on le voit mieux sur la figure 2, selon un aspect de l'invention, le canal d'amenée 6 est formé, à son entrée, par un alésage coaxial borgne d'un élément de clapet tubulaire 7 monté stationnaire dans l'extrémité de connexion du bloc détendeur 1, l'alésage borgne 6 débouchant vers l'extérieur par des passages radiaux 8 formés au-dessous d'une tête d'extrémité élargie 9 de l'élément 7.As we see best on the figure 2 according to one aspect of the invention, the inlet duct 6 is formed, at its inlet, by a blind coaxial bore of a tubular valve member 7 mounted stationary in the connection end of the expansion unit 1, the blind bore 6 opening outwards through radial passages 8 formed below an enlarged end head 9 of the element 7.

Selon un aspect de l'invention, autour de l'élément de clapet stationnaire 9 et monté à coulissement un siège annulaire 10 ayant une extrémité extérieure annulaire en saillie ou collerette 11 formant une face annulaire d'extrémité 12 autour de la tête 9, l'évidemment intérieur de la collerette annulaire 11 se raccordant intérieurement avec l'alésage de coulissement du siège 10 sur l'élément tubulaire 9 par une arête de siège 90 normalement sollicitée en engagement avec la face tronconique arrière 13 de la tête 9 par un ressort 23 prenant appui dans le bloc détendeur 1 et repoussant le siège 10 vers l'extérieur.According to one aspect of the invention, around the stationary valve member 9 and slidably mounted an annular seat 10 having an annular projecting or flanging outer end 11 forming an annular end face 12 around the head 9, obviously inside the annular flange 11 connecting internally with the sliding bore of the seat 10 on the tubular element 9 by a seat edge 90 normally biased in engagement with the rear frustoconical face 13 of the head 9 by a spring 23 supporting in the regulator block 1 and pushing the seat 10 outwardly.

Dans le mode de réalisation représenté, le corps de robinet 3 comporte, autour du canal 14 d'amenée de gaz sous pression en provenance d'un conteneur ou bouteille de gaz sous pression une cuvette de même dimension transversale que la collerette 11 et définissant un épaulement interne annulaire 15 coopérant en engagement, lors du pressage du corps de robinet 3 par la vis 5 contre le bloc détendeur 1, avec la face annulaire d'extrémité 12 du siège mobile 10, repoussant ainsi celui-ci vers l'intérieur à l'encontre du ressort 14 et ouvrant le passage entre l'arête de siège 90 et la face 13 de la tête 9. Le recul du siège 10 dans le bloc détendeur 1 est limité par la venue en butée d'un épaulement arrière 91 du siège contre un épaulement correspondant du corps 1.In the embodiment shown, the valve body 3 comprises, around the channel 14 for supplying pressurized gas from a container or bottle of pressurized gas a bowl of the same transverse dimension as the collar 11 and defining a annular inner shoulder 15 cooperating in engagement, during the pressing of the valve body 3 by the screw 5 against the expander block 1, with the annular end face 12 of the movable seat 10, thus pushing it inwardly to the against the spring 14 and opening the passage between the seat edge 90 and the face 13 of the head 9. The recoil of the seat 10 in the expansion unit 1 is limited by the abutment of a rear shoulder 91 of the seat against a corresponding shoulder of the body 1.

Dans le mode de réalisation représenté, l'étanchéité en configuration de connexion entre l'épaulement 15 du corps 3 et la face annulaire d'extrémité 12 du siège 10 est assurée par un joint 16 monté dans le fond de la cuvette du corps de robinet 3 et l'étanchéité entre le siège mobile 10 et l'élément de clapet stationnaire 9 est assurée par un joint coulissant 17 monté dans le siège 10. Le positionnement des joints 16 et 17 entre les deux pièces peut être inversé.In the embodiment shown, the sealing configuration in connection between the shoulder 15 of the body 3 and the annular end face 12 of the seat 10 is provided by a seal 16 mounted in the bottom of the bowl of the valve body 3 and the seal between the movable seat 10 and the stationary valve member 9 is provided by a sliding joint 17 mounted in the seat 10. The positioning of the seals 16 and 17 between the two parts can be reversed.

Dans le mode de réalisation pour connexion de type « DIN » représenté sur les figures 3 à 5, on retrouve l'extrémité de connexion du bloc détendeur 1 avec son élément de clapet stationnaire 9 entouré du siège mobile 10, sollicité en position d'obturation par le ressort 23, cet équipage étant ici destiné à être entièrement reçu dans une cuvette creuse 18 du corps de robinet 3 formant, dans son fond, toujours autour du canal 14 d'amenée de gaz sous pression, l'épaulement de butée 15 et comportant une extrémité avant taraudée destinée à être vissée dans l'extrémité tubulaire filetée 19 du bloc détendeur 1 abritant le siège mobile 10. Comme on le voit sur les figures 3 à 5, le corps de robinet 3, supportant le robinet d'ouverture / fermeture 20, est solidaire, dans ce mode de réalisation d'une embase filetée 21 destinée à être montée dans le col d'une bouteille de gaz sous pression (non représentée).In the embodiment for "DIN" type connection represented on the Figures 3 to 5 , there is the connecting end of the expansion unit 1 with its stationary valve member 9 surrounded by the movable seat 10, biased in the closed position by the spring 23, this crew being here intended to be fully received in a hollow bowl 18 the valve body 3 forming, in its bottom, always around the channel 14 for supplying pressurized gas, the abutment shoulder 15 and having a threaded front end intended to be screwed into the threaded tubular end 19 of the pressure reducer block 1 housing the mobile seat 10. As can be seen on the Figures 3 to 5 , the valve body 3, supporting the opening / closing valve 20, is integral, in this embodiment of a threaded base 21 to be mounted in the neck of a pressurized gas cylinder (not shown).

Comme on le voit sur la figure 5, lorsque l'extrémité filetée 19 du bloc détendeur 1 est vissée dans la cavité 18 du corps de robinet 3, l'épaulement 15 vient porter contre la face annulaire d'extrémité 12 du siège mobile 10 pour repousser celui-ci vers l'intérieur, à l'encontre du ressort 23, et ouvrir le passage entre la surface de contact arrière 13 et l'arête de siège 90.As we see on the figure 5 when the threaded end 19 of the pressure reducer block 1 is screwed into the cavity 18 of the valve body 3, the shoulder 15 bears against the annular end face 12 of the mobile seat 10 to push the latter inwards. , against the spring 23, and open the passage between the rear contact surface 13 and the seat edge 90.

Dans le mode de réalisation représenté, l'étanchéité entre les faces de butée 12 et 15 est assurée par un joint torique 16 monté dans le siège mobile 10 et l'étanchéité à coulissement de ce dernier est assurée par un joint coulissant 17 coopérant ici avec la paroi périphérique d'un fût 22 de montage de l'élément de clapet stationnaire 9 dans le bloc détendeur 1. Les montages des joints 16 et 17 peuvent également être inversés.In the embodiment shown, the seal between the abutment faces 12 and 15 is provided by an O-ring 16 mounted in the movable seat 10 and the sliding seal of the latter is provided by a sliding joint 17 cooperating here with the peripheral wall of a shank 22 for mounting the stationary valve member 9 in the expander block 1. The assemblies of the seals 16 and 17 can also be reversed.

On comprendra de ce qui précède, que, avec l'agencement selon l'invention, au repos en position de stockage ou lavage, le passage d'entrée du canal d'amenée 6 est hermétiquement obturé, la simple connexion du bloc détendeur 1 avec le corps de robinet 3 ouvrant ce passage pour créer et maintenir une section d'entrée déterminée stable suffisante pour satisfaire les performances respiratoires d'un utilisateur du gaz respiratoire détendu, quelle que soit la haute pression d'alimentation de ce dernier.It will be understood from the foregoing that, with the arrangement according to the invention, at rest in the storage or washing position, the inlet passage of the supply channel 6 is hermetically sealed, the simple connection of the regulator block 1 with the valve body 3 opening this passageway to create and maintain a stable determined inlet section sufficient to meet the respiratory performance of a relaxed respiratory gas user, regardless of the high feed pressure of the latter.

De plus, l'agencement selon l'invention, avec son siège mobile, autorise une rotation du bloc détendeur par l'utilisateur même dans la configuration connectée sous pression, les utilisateurs ayant la fâcheuse habitude de forcer sur la connexion du bloc détendeur pour ramener les sorties moyenne pression de celui-ci dans une position déterminée. Le siège mobile selon l'invention donne un degré de liberté à la connexion dans l'axe du corps de robinet ce qui évite la possibilité d'amorcer un couple de desserrage du bloc détendeur.In addition, the arrangement according to the invention, with its mobile seat, allows a rotation of the pressure reducer block by the user even in the configuration connected under pressure, the users having the unfortunate habit of forcing on the connection of the regulator block to bring back the medium pressure outlets thereof in a determined position. The mobile seat according to the invention gives a degree of freedom to the connection in the axis of the valve body which avoids the possibility of initiating a loosening torque of the expander block.

Quoique l'invention ait été décrite en relation avec des modes de réalisation particuliers, elle ne s'en trouve pas limitée mais est susceptible de modifications et de variantes qui apparaîtront à l'homme du métier dans le cadre des revendications ci-après. Ainsi, en position de repos, l'extrémité extérieure du siège mobile 10 peut être recouverte d'un opercule de protection arrachable ou amovible.Although the invention has been described in relation to particular embodiments, it is not limited thereto but is subject to modifications and variations which will occur to those skilled in the art within the scope of the claims below. Thus, in the rest position, the outer end of the seat mobile 10 may be covered with a tear-off or removable protective cover.
