Abstract

A liquid fuel gas cartridge having a valve that prevents or reduces the unintended escape of pressurized fluid after the cartridge has been perforated.

Description

La présente invention concerne une cartouche de gaz combustible liquide.The present invention relates to a liquid fuel gas cartridge.

Il est connu d'utiliser des cartouches de gaz combustible liquide du type comprenant :

  • un réservoir présentant une partie perforable sur sa paroi, et
  • un dispositif destiné à empêcher ou diminuer l'échappement de fluide sous pression après perforation de la cartouche, comportant un clapet muni d'un joint destiné à être appliqué contre la paroi du réservoir autour de la partie perforable par des moyens élastiques destinée à prendre appui directement ou indirectement contre une paroi du réservoir. Un exemple est divulgué dans le document EP 0298 881 .
It is known to use liquid fuel gas cartridges of the type comprising:
  • a reservoir having a pierceable portion on its wall, and
  • a device for preventing or reducing the escape of pressurized fluid after perforation of the cartridge, comprising a valve provided with a seal intended to be applied against the wall of the reservoir around the pierceable part by elastic means intended to bear directly or indirectly against a wall of the tank. An example is disclosed in the document EP 0298 881 .

Ce type de cartouche permet effectivement de réduire ou de supprimer l'échappement du fluide en dehors de la cartouche, après perforation, pour autant que la cartouche soit utilisée conformément à son fonctionnement optimal.This type of cartridge effectively reduces or eliminates the escape of the fluid outside the cartridge, after perforation, provided that the cartridge is used in accordance with its optimal operation.

Une telle cartouche est notamment destinée à être utilisée avec un appareil à gaz comprenant un perforateur. Le perforateur doit pénétrer dans la cartouche verticalement au centre de la partie perforable, dans les conditions normales d'utilisation de l'appareil à gaz. Toutefois, lorsque l'appareil à gaz n'est pas monté sur la cartouche selon les instructions d'utilisation, il se peut que le perforateur perce la cartouche avec un angle par rapport à l'axe de la cartouche, ou de façon excentrée par rapport à la partie perforable.Such a cartridge is particularly intended for use with a gas apparatus comprising a perforator. The perforator must enter the cartridge vertically in the center of the pierceable part under normal conditions of use of the gas appliance. However, when the gas appliance is not mounted on the cartridge in accordance with the operating instructions, the perforator may pierce the cartridge at an angle to the axis of the cartridge, or eccentrically through the cartridge. relative to the pierceable part.

Dans ces conditions, les joints prévus entre la cartouche et l'appareil ne sont pas positionnés pour assurer l'étanchéité du montage, alors que le clapet destiné à éviter l'échappement est déplacé par le perforateur. En conséquence, un échappement du gaz peut se produire.Under these conditions, the joints provided between the cartridge and the device are not positioned to seal the assembly, while the valve to prevent the exhaust is moved by the perforator. As a result, a gas escape can occur.

Le problème technique à la base de l'invention est donc de fournir une cartouche qui ne permette pas un échappement du fluide lorsque le montage de l'appareil sur la cartouche est effectué selon un positionnement ne correspondant pas aux conditions d'utilisation normales.The technical problem underlying the invention is therefore to provide a cartridge that does not allow an escape of the fluid when the mounting of the device on the cartridge is performed in a position that does not correspond to the normal conditions of use.

A cet effet, la présente invention a pour objet une cartouche du type précité, caractérisé en ce que le clapet comporte, en regard de la partie perforable :

  • une partie centrale située à une première distance de la partie perforable, inférieure à la longueur de pénétration dans le réservoir de la cartouche (2) et
  • une partie périphérique située à une seconde distance de la partie perforable, supérieure à la longueur de pénétration dans le réservoir de la cartouche (2).
For this purpose, the subject of the present invention is a cartridge of the aforementioned type, characterized in that the valve comprises, opposite the pierceable part:
  • a central portion located at a first distance from the pierceable portion, less than the length of penetration into the reservoir of the cartridge (2) and
  • a peripheral portion located at a second distance from the pierceable portion, greater than the length of penetration into the reservoir of the cartridge (2).

Grâce aux dispositions selon l'invention, si la cartouche est mal positionnée par rapport un appareil à gaz, et que le perforateur de cet appareil pénètre dans le réservoir de façon inclinée par rapport à l'axe du réservoir, ou décalée par rapport au centre de la partie perforable, ce perforateur n'entrera pas en contact avec la partie centrale du clapet. Au contraire, la pointe du perforateur sera située en regard de la partie périphérique du clapet, située par rapport à la partie perforable à une distance supérieure à la longueur du perforateur pénétrant dans la cartouche. En conséquence, le perforateur ne déplace pas le clapet, et l'échappement de gaz est évité.Thanks to the provisions according to the invention, if the cartridge is incorrectly positioned relative to a gas appliance, and the perforator of this appliance enters the tank in an inclined manner with respect to the axis of the tank, or offset with respect to the center the piercing part, this drill will not come into contact with the central part of the valve. On the contrary, the tip of the perforator will be located opposite the peripheral portion of the valve, located relative to the perforable portion at a distance greater than the length of the perforator penetrating the cartridge. As a result, the perforator does not move the valve, and gas escape is avoided.

Dans des conditions normales d'utilisation, le perforateur étant sensiblement dans l'axe du réservoir, la pointe du perforateur entre en contact de la partie centrale du clapet, située par rapport à la partie perforable à une distance inférieure à la longueur du perforateur pénétrant dans la cartouche. Le perforateur déplace ainsi le clapet, et le gaz peut être délivré à l'extérieur de la cartouche.Under normal conditions of use, the perforator being substantially in the axis of the reservoir, the tip of the perforator comes into contact with the central portion of the valve, located relative to the perforable portion at a distance less than the length of the penetrating perforator in the cartridge. The perforator thus moves the valve, and the gas can be delivered to the outside of the cartridge.

Avantageusement, le clapet comporte une portion de support du joint, à l'extérieur de la zone périphérique, comprenant un rebord à l'extérieur duquel est logé le joint.Advantageously, the valve comprises a support portion of the seal, outside the peripheral zone, comprising a flange outside which is housed the seal.

Le rebord permet de protéger le joint contre des dégradations dues à la pointe du perforateur si celle-ci pénètre le réservoir de façon excentrée ou inclinée par rapport à la partie perforable. En outre, ce rebord permet de protéger le joint du contact de copeaux découpés lors de la perforation de la cartouche.The flange protects the seal against damage from the tip of the perforator if it penetrates the tank eccentrically or inclined relative to the pierceable portion. In addition, this flange protects the seal of the cut chips contact during the perforation of the cartridge.

Selon un mode de réalisation, le joint est logé dans une gorge de la portion de support, tournée vers la paroi du réservoir. La gorge forme en particulier le rebord de protection.According to one embodiment, the seal is housed in a groove of the support portion, facing the tank wall. The groove in particular forms the protective rim.

Avantageusement, le joint est disposé de façon à appuyer sur la paroi du réservoir dans une zone extérieure à la partie perforable.Advantageously, the seal is arranged to press the wall of the reservoir in an area outside the pierceable portion.

Ce positionnement du joint permet de protéger celui-ci contre des dégradations dues à la pointe du perforateur si celle-ci pénètre le réservoir de façon excentrée ou inclinée par rapport à la partie perforableThis positioning of the seal makes it possible to protect it against damage due to the tip of the perforator if it penetrates the reservoir in an off-center or inclined manner with respect to the pierceable part.

Avantageusement, les moyens élastiques prennent appui sur un support fixé, notamment par soudure, sur la paroi du réservoir.Advantageously, the resilient means bear on a fixed support, in particular by welding, on the tank wall.

Selon un mode de réalisation, la cartouche comprend des moyens de retenue du clapet par rapport au support, destinés à rendre le clapet imperdable par rapport au support.According to one embodiment, the cartridge comprises means for retaining the valve relative to the support, intended to make the valve captive relative to the support.

Ces dispositions permettent au clapet et au support, ainsi qu'aux moyens élastiques de rester solidaires avant la fixation du support sur la cartouche.These arrangements allow the valve and the support, and the elastic means to remain secured before fixing the support on the cartridge.

Selon un mode de réalisation représenté sur les figures 1 et 2, une cartouche 2 de gaz combustible liquide selon l'invention comprend un réservoir 3 présentant une paroi périphérique cylindrique prolongée d'un côté par un dôme 4, et fermée de l'autre côté par un fond serti 5.According to an embodiment shown on the Figures 1 and 2 , a cartridge 2 of liquid fuel gas according to the invention comprises a reservoir 3 having a cylindrical peripheral wall extended on one side by a dome 4, and closed on the other side by a crimped bottom 5.

La paroi du réservoir 3 comprend une partie perforable 6 en forme de coupelle concave située au sommet du dôme, sur l'axe A de la paroi périphérique cylindrique du réservoir 3.The wall of the tank 3 comprises a perforable portion 6 in the form of a concave cup located at the top of the dome, on the axis A of the cylindrical peripheral wall of the tank 3.

La cartouche 2 comporte, à l'intérieur du réservoir 3, un dispositif destiné à empêcher ou diminuer l'échappement de fluide sous pression après perforation de la cartouche.The cartridge 2 comprises, inside the tank 3, a device for preventing or reducing the escape of pressurized fluid after perforation of the cartridge.

Ce dispositif comporte un clapet 7 muni d'un joint 8 destiné à être appliqué contre la paroi du réservoir 3 autour de la partie perforable 6 par un ressort hélicoïdal 9 s'appuyant sur un support 10 soudé sur la paroi du réservoir 3, autour de la partie perforable 6, à distance de celle-ci.This device comprises a valve 7 provided with a gasket 8 intended to be applied against the wall of the tank 3 around the pierceable part 6 by a helical spring 9 resting on a support 10 welded to the wall of the tank 3, around the pierceable portion 6, at a distance therefrom.

Le clapet 7 comporte, en regard de la partie perforable 6 :

  • une partie centrale 12 située à une première distance d1 de la partie perforable 6, inférieure à la longueur de la portion d'un perforateur P destiné à pénétrer dans le réservoir 3 et
  • une partie périphérique 13 située à une seconde distance d2 de la partie perforable 6, supérieure à la longueur de la portion d'un perforateur P destiné à pénétrer dans le réservoir 3.
The valve 7 comprises, opposite the perforable part 6:
  • a central portion 12 located at a first distance d1 from the perforable portion 6, less than the length of the portion of a perforator P intended to penetrate the reservoir 3 and
  • a peripheral portion 13 located at a second distance d2 from the pierceable portion 6, greater than the length of the portion of a perforator P intended to penetrate the reservoir 3.

Le clapet 7 comporte de plus une portion 14 de support du joint 8, à l'extérieur de la partie périphérique 13, comprenant une gorge 15 de logement du joint 8, tournée vers la paroi du réservoir 3. Le joint est disposé de façon à appuyer sur la paroi du réservoir 3 dans une zone extérieure à la partie perforable 6.The valve 7 further comprises a portion 14 for supporting the gasket 8, outside the peripheral portion 13, comprising a groove 15 for housing the gasket 8, facing the wall of the tank 3. The gasket is arranged so as to press on the wall of the tank 3 in an area outside the pierceable part 6.

Du côté opposé à la partie perforable 6, le clapet comporte un épaulement extérieur 16 sur lequel prend appui le ressort 9. Le clapet 7 comprend également deux pattes élastiques 18 s'étendant au travers d'une ouverture 19 dans le support 10, et comprenant à son extrémité une butée 20.

The valve 7 also comprises two elastic tabs 18 extending through an opening 19 in the support 10, and comprising at its end a stop 20. These tabs constitute a means of retaining the valve 7 relative to the support, making it possible to make the valve 7 captive relative to the support before the latter is fixed in the reservoir 3.

Dans le mode de réalisation présenté sur les figures 1 et 2, le support 10 est constitué par une pièce comprenant une paroi latérale cylindrique, avec un retour extérieur 22 destiné à être fixé sur la paroi du réservoir 3, notamment par soudure, et un fond dans lequel est ménagé l'ouverture 19 dans laquelle s'engagent les pattes 18 du clapet.In the embodiment presented on the Figures 1 and 2 , the support 10 is constituted by a part comprising a cylindrical side wall, with an external return 22 intended to be fixed on the wall of the tank 3, in particular by welding, and a bottom in which the opening 19 is formed in which engage the flaps 18 of the valve.

Comme cela est visible sur la figure 2, si la cartouche est mal positionnée par rapport un appareil à gaz, par exemple du type représenté sur la figure 3, et que le perforateur P de cet appareil pénètre dans le réservoir de façon inclinée par rapport à l'axe du réservoir, ou décalée par rapport au centre de la partie perforable, ce perforateur n'entrera pas en contact avec la partie centrale 12 du clapet. Au contraire, la pointe du perforateur sera située en regard de la partie périphérique 13 du clapet, située par rapport à la partie perforable 6 à une distance d2 supérieure à la longueur du perforateur P pénétrant dans la cartouche.As is visible on the figure 2 , if the cartridge is incorrectly positioned relative to a gas appliance, for example of the type shown in the figure 3 , and that the perforator P of this apparatus enters the tank inclined with respect to the axis of the tank, or offset from the center of the pierceable part, this perforator will not come into contact with the central portion 12 of the valve. On the contrary, the tip of the perforator will be located opposite the peripheral portion 13 of the valve, located relative to the perforable portion 6 at a distance d2 greater than the length of the perforator P penetrating the cartridge.

Comme il va de soi, l'invention ne se limite pas à la forme de réalisation préférentielle décrite ci-dessus, à titre d'exemple non limitatif ; elle en embrasse au contraire toutes les variantes.It goes without saying that the invention is not limited to the preferred embodiment described above, by way of non-limiting example; on the contrary, it embraces all variants.
