Abstract

The valve comprises a fixed part (1, 2), a moving part (9) and a sealing joint (15). The sealing joint (15) is comprised of two portions (16, 17) which are axially separated by a cylindrical part (18). During the filling operation, the connector (30) of the filler tank displaces the moving part (9) downwardly against the action of a spring (10). A protuberance (31) cooperates with the portion (16) of the seal to move downwardly the latter. A ramp (32) guides the portion (17) of the seal towards the connector (30). At the stroke end, said portion (17) is clamped between the fixed part (1, 2) and the connector (30) to provide for a complete tightness of the filling passage (25) to the outside and a perfect separation of both filling (25) and discharge (21) passages. In a closed position of the valve, the upper portion of the part (9) engages the opening provided for the passage of the connector (30).

Description

La présente invention concerne une valve pour le remplissage d'un récipient à gaz liquéfié au moyen d'un réservoir de recharge muni d'un raccord cylindrique, cette valve présentant au moins une pièce fixe, une pièce mobile montée de façon coulissante dans une chambre axiale de la pièce fixe et un joint d'étanchéité susceptible d'être déplacé axialement sur une course prédéterminée par la pièce mobile, la chambre axiale débouchant par un orifice sur une face extérieure de la pièce fixe, la valve présentant deux-passages, l'un étant un passage de remplissage du gaz liquéfié et l'autre un passage d'échappement pour mettre l'intérieur du récipient en communication avec l'extérieur, cette valve étant destinée à être actionnée par l'introduction du raccord dans la chambre axiale pour déplacer la pièce mobile et le joint contre l'action d'un ressort d'une position de fermeture où le joint est en contact avec la pièce fixe et la pièce mobile de façon à obturer les deux passages vers une position de remplissage où le joint est en contact avec la pièce fixe et le raccord pour ouvrir les deux passages.The present invention relates to a valve for filling a liquefied gas container by means of a refill tank provided with a cylindrical connection, this valve having at least one fixed part, a moving part slidably mounted in a chamber. axial of the fixed part and a seal capable of being moved axially over a predetermined stroke by the moving part, the axial chamber opening out through an orifice on an external face of the fixed part, the valve having two passages, l 'one being a liquefied gas filling passage and the other an exhaust passage for bringing the interior of the container into communication with the outside, this valve being intended to be actuated by the introduction of the connector into the axial chamber to move the moving part and the seal against the action of a spring from a closed position where the seal is in contact with the fixed part and the moving part so as to close the two passages towards a position filling where the seal is in contact with the fixed part and the fitting to open the two passages.

Une valve de ce type, destinée notamment à équiper un briquet à gaz, est décrite dans CH-A-355 167 et comporte un joint constitué par un anneau en forme de tore logé dans une rainure de la pièce fixe en regard de l'orifice du passage d'échappement.A valve of this type, intended in particular to equip a gas lighter, is described in CH-A-355 167 and comprises a seal constituted by a ring in the shape of a torus housed in a groove of the fixed part opposite the orifice of the exhaust passage.

Les valves de ce genre sont habituellement munies d'un couvercle ou bouchon qui doit être enlevé pour permettre le remplissage. L'expérience montre que ce bouchon est souvent perdu par l'usagé. De plus, ce bouchon est généralement vissé, ce qui complique l'opération de remplissage. Plus rarement, le bouchon est introduit à friction dans l'orifice et, dans ce cas, il est de fabrication relativement compliquée, car si l'on veut qu'il vienne à fleur de la face du récipient qui est équipé de la valve, il doit présenter un organe escamotable pouvant être amené en saillie pour permettre son extraction lorsque le remplissage doit être effectué.Valves of this type are usually provided with a cover or plug which must be removed to allow filling. Experience shows that this plug is often lost by the user. In addition, this cap is generally screwed, which complicates the filling operation. More rarely, the plug is introduced frictionally into the orifice and, in this case, it is relatively complicated to manufacture, because if it is desired to come flush with the face of the container which is equipped with the valve, it must have a retractable member which can be brought into projection to allow its extraction when filling must be carried out.

On connaît également une valve de ce genre, décrite dans US-A-3 039 499. Cette valve comporte un joint inséré entre deux pièces mobiles disposées l'une à la suite de l'autre et entourant une tige centrale fixe. Dans cette valve, le raccord du réservoir de recharge n'est pas en contact avec le joint d'étanchéité, ce qui peut être la cause d'importantes pertes de gaz liquéfié lors du remplissage. De plus, la tige centrale indispensable pour cette valve exclut l'utilisation d'un certain nombre de réservoirs de recharge.A valve of this type is also known, described in US-A-3 039 499. This valve comprises a seal inserted between two moving parts arranged one after the other and surrounding a fixed central rod. In this valve, the connection of the refill tank is not in contact with the seal, which can be the cause of significant losses of liquefied gas during filling. In addition, the central rod essential for this valve excludes the use of a number of refill tanks.

L'invention a pour but de remédier aux inconvénients des antériorités précitées et elle est caractérisée à cet effet en ce que la pièce mobile présente une portion terminale dont le diamètre correspond à celui dudit orifice et en ce que le joint d'étanchéité, de forme générale cylindrique, est disposé entre la pièce fixe et la pièce mobile, ce joint coopérant avec ces pièces de façon à constituer, en position fermée de la valve, une butée pour retenir la pièce mobile contre l'action dudit ressort dans une position telle que sa portion terminale soit située sensiblement dans le plan de la face externe de la pièce fixe, ledit raccord étant en position de remplissage entouré sur une partie de sa surface cylindrique par une portion du joint d'étanchéité.The invention aims to remedy the drawbacks of the aforementioned prior art and it is characterized for this purpose in that the movable part has an end portion whose diameter corresponds to that of said orifice and in that the seal, of shape generally cylindrical, is disposed between the fixed part and the moving part, this joint cooperating with these parts so as to constitute, in the closed position of the valve, a stop for retaining the moving part against the action of said spring in a position such that its end portion is located substantially in the plane of the external face of the fixed part, said connector being in the filling position surrounded on a part of its cylindrical surface by a portion of the seal.

L'invention permet d'obtenir une combinaison triple d'avantages en ceci que la partie terminale de la pièce mobile joue le rôle de bouchon, que les pertes de gaz liquéfié lors du remplissage sont évitées et que l'absence de tige axiale permet l'utilisation d'un grand nombre de réservoirs de recharge munis d'un simple embout cylindrique.The invention provides a triple combination of advantages in that the end part of the moving part acts as a stopper, that losses of liquefied gas during filling are avoided and that the absence of an axial rod allows the use of a large number of refill tanks fitted with a simple cylindrical tip.

Selon une forme d'exécution avantageuse, le joint d'étanchéité comprend deux portions axialement séparées par une partie cylindrique, une première de ces deux portions étant en contact avec la pièce mobile et coopérant avec cette dernière pour déplacer le joint d'une première position vers une deuxième position lorsque la pièce mobile est déplacée de la position de fermeture vers la position de remplissage, la deuxième portion du joint étant agencée de façon à obturer le passage d'échappement lorsque le joint se trouve dans ladite première position et à être enserrée entre le raccord cylindrique et les parois de la chambre axiale de la pièce fixe dans une position éloignée du passage d'échappement, lorsque le joint est amené axialement vers ladite seconde position.According to an advantageous embodiment, the seal comprises two portions axially separated by a cylindrical part, a first of these two portions being in contact with the moving part and cooperating with the latter to move the seal from a first position towards a second position when the moving part is moved from the closed position to the filling position, the second portion of the seal being arranged so as to close the exhaust passage when the seal is in said first position and to be clamped between the cylindrical connector and the walls of the axial chamber of the fixed part in a position remote from the exhaust passage, when the seal is brought axially towards said second position.

Grâce à cette disposition particulière du joint en deux portions axialement séparées par une partie cylindrique, le joint est amené, lors du remplissage, par la pièce mobile dans une position telle qu'il assure une obturation complète entre le raccord et la pièce fixe de la valve et une séparation parfaite des passages de remplissage et d'échappement. Cette construction permet de réaliser une valve d'un fonctionnement très sûr.Thanks to this particular arrangement of the seal in two axially separated portions by a cylindrical part, the seal is brought, during filling, by the moving part into a position such that it ensures complete sealing between the fitting and the fixed part of the valve and a perfect separation of the filling and exhaust passages. This construction makes it possible to produce a valve of very safe operation.

Le dessin annexé représente schématiquement et à titre d'exemple une forme d'exécution de la valve, objet de l'invention.The accompanying drawing shows schematically and by way of example an embodiment of the valve, object of the invention.

La figure 1 est une vue en coupe longitudinale de la valve en position de fermeture.Figure 1 is a longitudinal sectional view of the valve in the closed position.

La figure 2 illustre la même valve en position de remplissage.Figure 2 illustrates the same valve in the filling position.

La valve décrite en référence aux figures 1 et 2 comprend une pièce fixe constituée en deux parties 1 et 2. La partie 1 présente un filetagé 3 permettant de fixer la valve dans un alésage fileté 4 correspondant d'un récipient 5 à gaz liquéfié ". dont elle permet le remplissage. L'étanchéité entre la valve et le récipient 5 est assurée par Lrn joint 6. Le bord inférieur 7 de la partie 1 est recourbé pour retenir en position la partie 2 qui comporte une portion tubulaire 8 en saillie. Une pièce mobile 9 est montée de façon coulissante dans cette portion tubulaire 8 et dans une chambre axiale 27 de la valve et est soumise à l'action d'un ressort 10 prenant appui, d'une part, contre un épaulement 11 de cette pièce et, d'autre part, contre le fond 12 de la partie 2. Cette pièce 9 présente à sa partie supérieure une portion 13 pénétrant dans l'orifice 35 du corps de la valve, qui est délimité par un rebord interne 14. La face supérieure 36 de cette pièce comporte au moins une rainure radiale 37 destinée à faciliter l'écoulement du gaz liquéfié. Dans la position de fermeture de la valve illustrée à la figure 1, la face supérieure de la pièce 9 vient sensiblement dans le plan de la face externe de la partie 1.The valve described with reference to FIGS. 1 and 2 comprises a fixed part made up of two parts 1 and 2. Part 1 has a thread 3 making it possible to fix the valve in a threaded bore 4 corresponding to a container 5 for liquefied gas ". The sealing between the valve and the container 5 is ensured by L rn joint 6. The lower edge 7 of the part 1 is curved to retain in position the part 2 which has a tubular portion 8 projecting. A moving part 9 is slidably mounted in this tubular portion 8 and in an axial chamber 27 of the valve and is subjected to the action a spring 10 bearing, on the one hand, against a shoulder 11 of this part and, on the other hand, against the bottom 12 of the part 2. This part 9 has at its upper part a portion 13 penetrating into the orifice 35 of the valve body, which is delimited by an internal rim 14. The upper face 36 of this part comprises at least one radial groove 37 intended to facilitate the flow of the liquefied gas. In the closed position of the valve illustrated in FIG. 1, the upper face of the part 9 comes substantially in the plane of the external face of the part 1.

La valve représentée comprend un joint d'étanchéité 15 en élastomère comportant deux portions annulaires 16, 17 axialement séparées par une partie cylindrique 18. Une première 16 de ces deux portions présente une section sensiblement rectangulaire, dont une première face s'appuie contre le côté cylindrique 19 de la pièce mobile 9 et dont une deuxième face est appliquée contre l'épaulement 11, lorsque la valve se trouve en position de fermeture. Dans cette position, l'autre portion 17 du joint est sollicitée par le ressort 10 dans un logement 20 prévu dans la partie supérieure de la pièce fixe. L'intérieur du récipient 5 communique avec ce logement 20 par un passage d'échappement 21 constitué par un perçage 22, un espace cylindrique 23 compris entre les deux parties fixes 1, 2 et par des ouvertures 24 aboutissant dans le logement 20. Soumise à l'action du ressort 10 par l'intermédiaire de la pièce mobile 9, la portion 17 obture complètement les ouvertures 24 du passage d'échappement, lorsque la valve est fermée.The valve shown comprises an elastomer seal 15 comprising two annular portions 16, 17 axially separated by a cylindrical portion 18. A first 16 of these two portions has a substantially rectangular section, of which a first face is pressed against the side cylindrical 19 of the movable part 9 and a second face of which is applied against the shoulder 11, when the valve is in the closed position. In this position, the other portion 17 of the seal is biased by the spring 10 in a housing 20 provided in the upper part of the fixed part. The interior of the container 5 communicates with this housing 20 by an exhaust passage 21 constituted by a bore 22, a cylindrical space 23 included between the two fixed parts 1, 2 and by openings 24 leading to the housing 20. Subject to the action of the spring 10 via the moving part 9, the portion 17 completely closes the openings 24 of the exhaust passage, when the valve is closed.

Ce passage d'échappement est entièrement séparé du passage de remplissage 25 du gaz liquéfié constitué par des ouvertures 26 prévues dans le fond 12, la chambre axiale 27 et les rainures longitudinales 28 ménagées dans la partie supérieure 29 de la pièce mobile 9 (fig. 2). Ces rainures 28 ne s'étendent pas jusqu'à l'épaulement 11 pour permettre l'obturation du passage de remplissage 25 par la première portion 16 du joint lorsque la valve est fermée.This exhaust passage is entirely separate from the filling passage 25 for the liquefied gas constituted by openings 26 provided in the bottom 12, the axial chamber 27 and the longitudinal grooves 28 formed in the upper part 29 of the moving part 9 (fig. 2). These grooves 28 do not extend to the shoulder 11 to allow the filling passage 25 to be closed off by the first portion 16 of the seal when the valve is closed.

Lors de l'ouverture de la valve, la pièce mobile 9 est déplacée par l'introduction du raccord de remplissage 30 cylindrique d'un réservoir de recharge, non illustré, dans l'ouverture supérieure 35 de la valve. Le joint d'étanchéité 15 reste immobile jusqu'à ce qu'une saillie 31 de la pièce mobile 9 entre en contact avec la première portion 16 du joint. Le raccord 30 est à ce moment bien engagé entre les deux portions 17 du joint 15, mais ne touche pas ces dernières. La partie 2 de la pièce fixe comporte, au niveau du logement 20, une rampe 32 contre laquelle la portion 17 du joint est appuyée. Cette rampe 32 est agencée de façon à amener la portion 17 vers une position radialement plus interne de la valve pour entrer en contact avec la paroi cylindrique 33 du raccord 30, lorsque le joint 15, en contact avec la saillie 31, est déplacé vers le bas par la pièce mobile 9 (voir fig. 2). Arrivée à la partie inférieure de cette rampe 32, la portion 17 du joint 9 est entièrement enserrée entre le raccord 30 et la partie 2 de la pièce fixe pour assurer une étanchéité complète du passage de remplissage 25 vers l'extérieur. La pièce mobile 9 est arrêtée dans sa course par une rondelle 34 butant contre la partie supérieure de la portion tubulaire fixe 8, tandis que le joint 15 prend appui par sa portion 16 contre un épaulement 38 de la chambre 27. Une pression supplémentaire sur le réservoir de recharge permet d'ouvrir la valve de retenue de ce dernier contre l'action d'un ressort, non illustré. Il est important que le ressort 10 soit choisi de façon que sa force soit plus faible que celle des ressorts utilisés dans les valves des réservoirs de recharge commercialisés.When the valve opens, the moving part 9 is moved by the introduction of the cylindrical filling connector 30 of a refill tank, not shown, in the upper opening 35 of the valve. The seal 15 remains stationary until a projection 31 of the movable part 9 comes into contact with the first portion 16 of the seal. The connector 30 is at this time well engaged between the two portions 17 of the seal 15, but does not touch the latter. Part 2 of the fixed part comprises, at the level of the housing 20, a ramp 32 against which the portion 17 of the seal is supported. This ramp 32 is arranged so as to bring the portion 17 to a radially more internal position of the valve to come into contact with the cylindrical wall 33 of the connector 30, when the seal 15, in contact with the projection 31, is moved towards the bottom by the moving part 9 (see fig. 2). Arriving at the lower part of this ramp 32, the portion 17 of the seal 9 is entirely enclosed between the connector 30 and the part 2 of the fixed part to ensure complete sealing of the filling passage 25 to the outside. The moving part 9 is stopped in its course by a washer 34 abutting against the upper part of the fixed tubular portion 8, while the seal 15 bears by its portion 16 against a shoulder 38 of the chamber 27. Additional pressure on the refill tank opens the latter's retaining valve against the action of a spring, not shown. It is important that the spring 10 is chosen so that its force is weaker than that of the springs used in the valves of the refill tanks sold.

La valve de remplissage fonctionne de la manière suivante :

  • Le raccord 30 est introduit dans l'orifice 35 et déplace la pièce mobile 9 vers le bas contre l'action du ressort 10. Il n'est, à ce moment, pas en contact avec la portion 17 du joint d'étanchéité 15.
The filling valve works as follows:
  • The connector 30 is introduced into the orifice 35 and moves the movable part 9 downwards against the action of the spring 10. It is not, at this time, in contact with the portion 17 of the seal 15.

La saillie 31 entraîne ensuite le joint 9 par la portion 16 vers le bas. Il y a ouverture du passage d'échappement 21. Les portions 17 du joint, guidées par la rampe 32, entrent en contact avec le raccord 30 et enserrent fermement ce dernier. Le passage de remplissage 25 est entièrement fermé vers l'extérieur.The projection 31 then drives the seal 9 through the portion 16 downwards. There is opening of the exhaust passage 21. The portions 17 of the seal, guided by the ramp 32, come into contact with the connector 30 and firmly enclose the latter. The filling passage 25 is completely closed towards the outside.

La rondelle 34 bute contre la portion tubulaire 8. Une pression supplémentaire sur le réservoir de recharge permet l'ouverture de la valve de retenue du réservoir et l'écoulement du gaz liquéfié a travers le passage de remplissage dans le' récipient 5.The washer 34 abuts against the tubular portion 8. An additional pressure on the refill tank allows the opening of the tank retaining valve and the flow of the liquefied gas through the filling passage in the container 5.

Lorsque le récipient est rempli, du gaz liquéfié s'échappe par le passage d'échappement. L'usager est ainsi averti que le récipient est plein et il doit retirer le réservoir de recharge. La valve de retenue de ce dernier se ferme sous l'action de son ressort.When the container is filled, liquefied gas escapes through the exhaust passage. The user is thus warned that the container is full and must remove the refill tank. The latter's check valve closes under the action of its spring.

La pièce mobile 9 sollicitée par le ressort 10 remonte. Lorsque la portion 16 du joint entre en contact avec l'épaulement 11, le passage d'admission est fermé et le joint 15 est amené par la pièce mobile 9 vers le haut. La portion 17 pénètre dans le logement 20 et obture les ouvertures 24 du passage d'échappement qui à son tour est alors fermé. Le joint 15 est alors serré par le ressort 10 entre la paroi supérieure de la chambre 20 et l'épaulement 11. Il assure ainsi une fermeture étanche du récipient 5 et constitue une butée pour retenir la pièce 9 dans une position telle que sa face supérieure soit sensiblement dans le plan de la face extérieure du corps de la soupape.The moving part 9 urged by the spring 10 rises. When the portion 16 of the seal comes into contact with the shoulder 11, the intake passage is closed and the seal 15 is brought by the movable part 9 upwards. The portion 17 enters the housing 20 and closes the openings 24 of the exhaust passage which in turn is then closed. The seal 15 is then clamped by the spring 10 between the upper wall of the chamber 20 and the shoulder 11. It thus ensures a tight closure of the container 5 and constitutes a stop for retaining the part 9 in a position such that its upper face or substantially in the plane of the outer face of the valve body.
