Description

Dispositif d'obturation du circuit de gaz dans un briquet à gaz liquéfié. Device for closing the gas circuit in a liquefied gas lighter.
La présente invention concerne un dispositif d'obturation du circuit de gaz dans un briquet à gaz liquéfié. De tels dispositifs d'obturation sont, généralement. constitués d'un clapet, élastique porté par un support, qui sous L'action d'un ressort, appuie de façon étanche ledit clapet sur un siège disposé sur le circuit de gaz..The present invention relates to a device for closing the gas circuit in a liquefied gas lighter. Such shutters are, generally. consisting of a valve, elastic carried by a support, which under the action of a spring, presses said valve in a sealed manner on a seat arranged on the gas circuit.
Pour ouvrir ce circuit de gaz, il suffit de déplacer le support du clapet à l'encontre de l'action du ressort.To open this gas circuit, simply move the valve support against the action of the spring.
Une méthode de fixation du clapet élastique d'obturation sur son support consiste à le sertir : le clapet, en forme de pastille, est placé dans un logement, situe à L'une des extrémités du support, et dont la paroi est rabattue radialement, soit en totalité soit en partie.One method of fixing the elastic shutter valve to its support consists of crimping it: the valve, in the form of a pellet, is placed in a housing, located at one of the ends of the support, and the wall of which is folded down radially, either in whole or in part.
Cette méthode, de mise en oeuvre relativement simple, présente cependant un double inconvénient, compte-tenu des dimensions du clapet dont le diamètre est de L'ordre de quelques millimètres : Si le sertissage est trop fort, le clapet se présente alors extérieurement sous forme d'un ménisque plus ou moins irrégulier et risque de ne pas assurer une obturation totale, tandis que si le sertissage n'est pas assez fort, le clapet risque, au bout de quelques temps, de resterplus ou moins collé sur le siège lorsque l'on retire le support et de se dessertir, et un tel dessertissage peut aboutir par la suite, à cause de la pression du gaz à laquelle est soumis le clapet, à une fuite incontrôlable.This method, which is relatively simple to implement, has however a double disadvantage, given the dimensions of the valve, the diameter of which is of the order of a few millimeters: If the crimping is too strong, the valve then appears externally in the form of a more or less irregular meniscus and may not ensure complete closure, while if the crimping is not strong enough, the valve may, after a while, remain more or less stuck on the seat when the 'the support is removed and to be crimped, and such crimping can result subsequently, because of the gas pressure to which the valve is subjected, to an uncontrollable leak.
Une autre méthode de fixation du clapet sur son support consiste à prévoir un clapet présentant une section axiale en forme de T ce qui donne non plus une forme de simple pastille mais de pastille avec une tige centrale. Dans ce cas, le sertissage a lieu sur cette tige et n'influence donc pas la surface du clapet qui viendra en contact avec le siège d'obturation. Mais la mise en place d'un tel clapet est très délicate et donc onéreuse, du fait que, comme il a été rappelé ci-dessus, le diamètre du clapet dans sa partie assurant l'obturation est de l'ordre de quelques millimètres, la tige étant évidemment de diamètre encore plus petit.Another method of fixing the valve on its support consists in providing a valve having an axial T-shaped section which gives no longer a simple pellet shape but a pellet with a central rod. In this case, the crimping takes place on this rod and therefore does not influence the surface of the valve which will come into contact with the shutter seat. But the establishment of such a valve is very delicate and therefore expensive, because, as has been recalled above, the diameter of the valve in its part ensuring the obturation is of the order of a few millimeters, the rod obviously being of even smaller diameter.
La présente invention se propose de remédier aux inconvénients des modes de fixation précédemment décrits du clapet élastique d'obturation sur son support.The present invention proposes to remedy the drawbacks of the previously described methods of fixing the elastic shutter valve on its support.
Elle a pour objet un dispositif d'obturation du circuit de gaz dans un briquet à gaz liquéfié dans lequel l'obturation est obtenue par appui, sur un siège disposé sur le circuit de gaz à contrôler, d'un clapet élastique porté par un support dans lequel ϋ est retenu par des moyens n'exerçant aucune contrainte sur La surface de contact dudit ciapet avec son siège, ce dispositif d'obturation étant caractérisé en ce que Le cLapet élastique est formé in situ dans un réceptacle prévu dans le support. Les figures jointes montrent des exemples de réalisation de l'invention, donnés à titre indicatif et non limitatif.It relates to a device for shutting off the gas circuit in a liquefied gas lighter in which the shutter is obtained by pressing, on a seat arranged on the gas circuit to be checked, an elastic valve carried by a support. in which ϋ is retained by means not exerting any constraint on the contact surface of said valve with its seat, this closure device being characterized in that the elastic valve is formed in situ in a receptacle provided in the support. The attached figures show exemplary embodiments of the invention, given by way of non-limiting illustration.
La figure L est une coupe partielle d'un briquet à gaz Liquéfié équipé d'un dispositif d'obturation suivant l'invention.Figure L is a partial section of a liquefied gas lighter equipped with a closure device according to the invention.
La figure 2 est une vue en perspective du clapet d'obturation de la figure l.Figure 2 is a perspective view of the shutter valve of Figure l.
La figure 3 est une coupe partielle d'un briquet à gaz liquéfié dans lequel le brûleur et le dispositif d'obturation, suivant l'invention, constituent une seule pièce.Figure 3 is a partial section of a liquefied gas lighter in which the burner and the shutter device, according to the invention, constitute a single piece.
La figure 4 montre une variante de réalisation. Dans Le briquet l partiellement dessiné sur la figure 1, le gaz qui se trouve à l'intérieur du briquet passe par le canai 2 dans L'espace Libre autour d'un porte détendeur 3 et, à travers le détendeur 4, arrive dans une chambre 5.Figure 4 shows an alternative embodiment. In the lighter partially drawn in FIG. 1, the gas which is inside the lighter passes through the channel 2 in the free space around a regulator holder 3 and, through the regulator 4, arrives in a room 5.
Un dispositif d'obturation 6, comprenant un clapet 7 et un support de clapet 8, assure l'obturation de la chambre 5, sous l'action d'un ressort non représenté et agissant dans le sens de la flèche 9, par anpui du clapet 7 sur le bord de l'orifice 10 qui Lui sert de siège.A closure device 6, comprising a valve 7 and a valve support 8, provides the closure of the chamber 5, under the action of a spring not shown and acting in the direction of the arrow 9, by anpui du valve 7 on the edge of the orifice 10 which serves as its seat.
Lorsque, par un moyenqueLconque ne faisant pas partie de l'invention, Le dispositif d'obturation 6 est déplacé en sens contraire de la flèche 9, le gaz passe par l'orifice 10 à une canalisation 11 qui débouche dans un brûleur non représenté.When, by a means that is not part of the invention, the closure device 6 is moved in the opposite direction to the arrow 9, the gas passes through the orifice 10 to a pipe 11 which opens into a burner not shown.
Le clapet 7,dont la forme particulière est illustrée figure 2, comprend trois parties. La partie 12 assurant l'obturation de l'orifice 10 est cylindrique. Elle se continue par une deuxième partie 13 également cylindrique mais de diamètre plus petit. Enfin, la troisième partie 14, cylindrique aussi,est disposée perpendiculairement à la deuxième partie.The valve 7, the particular shape of which is illustrated in FIG. 2, comprises three parts. The part 12 ensuring the closure of the orifice 10 is cylindrical. It is continued by a second part 13 also cylindrical but of smaller diameter. Finally, the third part 14, also cylindrical, is arranged perpendicular to the second part.
Cette forme a été obtenue par deux perçages dans le support 8 t un perçage axiai correspondant à la deuxième partie du clapet, un perçage radial correspondant à la troisième.This shape was obtained by two holes in the support 8 t an axiai hole corresponding to the second part of the valve, a radial hole corresponding to the third.
Il a suffi alors de mouler le clapet "in situ" c'est-à dire dans le logement qui lui est destiné. Du fait qu'elle présente, dans un plan perpendiculaire à l'axe du clapet, une section plus grande que celle de la partie 13, la partie 14 constitue un moyen de retenue du clapet dans son support sans exercer une contrainte quelconque sur la surface de contact du clapet avec son siège.It then suffices to mold the valve "in situ", that is to say in the housing intended for it. Because it has, in a plane perpendicular to the axis of the valve, a larger section than that of the part 13, the part 14 constitutes a means of retaining the valve in its support without exerting any stress on the surface contact of the valve with its seat.
Sur la figure 3, on a représenté partiellement un briquet 15 dans lequel le support 16 du clapet 17 obturant l'orifice 18 constitue également le brûleur qui reçoit le gaz par la canalisation 19 en position ouverte du clapet 17. Ce clapet a la forme d'un tronc de cône inversé qui a été obtenu en rabattant d'abord vers l'intérieur la paroi du logement cylindrique qui lui était destiné et en moulant alors le clapet "in situ".In FIG. 3, a lighter 15 is partially shown in which the support 16 of the valve 17 closing the orifice 18 also constitutes the burner which receives the gas through the pipe 19 in the open position of the valve 17. This valve has the form of 'an inverted truncated cone which was obtained by first folding inwards the wall of the cylindrical housing which was intended for it and then molding the valve "in situ".
Dans ce cas également, le moyen de retenue du clapet dans le support, moyen constitué par la diminution du diamètre du logement du clapet, n'exerce aucune contrainte sur la surface de contact du clapet avec son siège.In this case also, the means of retaining the valve in the support, means constituted by the reduction in the diameter of the housing of the valve, exerts no constraint on the contact surface of the valve with its seat.
Il est entendu que l'on peut, sans sortir de l'invention modifier des détails de construction ou adapter telle ou telle variante équivalente aux exemples proposés.It is understood that it is possible, without departing from the invention, to modify construction details or to adapt such or such variant equivalent to the examples proposed.
Par exemple, comme illustré par la figure 4, le clapet 20 pourrait être retenu dans son support par une barrette transversale 21 préalablement disposée dans le logement audit clapet 20. For example, as illustrated in FIG. 4, the valve 20 could be retained in its support by a transverse bar 21 previously arranged in the housing to said valve 20.
