Description

La présente invention concerne les briquets à gaz liquéfié.The present invention relates to liquefied gas lighters.

On sait que les briquets de ce type comportent un système détendeur-évaporateur destiné à assurer le passage du gaz dans la phase liquide, sous laquelle il est stocké, à la phase vapeur, sous laquelle il est distribué. Ce système est, d'autre part, habituellement utilisé pour réduire la pression du gaz jusqu'à la pression d'utilisation.It is known that lighters of this type include a regulator-evaporator system intended to ensure the passage of gas in the liquid phase, under which it is stored, to the vapor phase, under which it is distributed. This system is, on the other hand, usually used to reduce the gas pressure to the operating pressure.

Afin d'améliorer la sécurité de ces briquets, on a proposé de limiter la hauteur de flamme maximale qu'ils sont susceptibles de fournir, en disposant en amont du détendeur-évaporateur un dispositif limiteur de débit (voir FR-A No 2313638).In order to improve the safety of these lighters, it has been proposed to limit the maximum flame height that they are capable of providing, by having a flow limiting device upstream of the regulator-evaporator (see FR-A No 2313638).

Ces limiteurs de débit, du fait de leur position en amont du détendeur-évaporateur, opèrent une réduction de débit sur du gaz en phase liquide. Or on sait qu'un volume donné de gaz liquide fournit, après évaporation, un volume environ cinq fois plus important de phase gazeuse. Il en résulte que la restriction produite par un tel limiteur doit être importante en regard de celle réalisée dans le détendeur-évaporateur. r.These flow limiters, due to their position upstream of the expansion valve-evaporator, operate a flow reduction on gas in the liquid phase. Now we know that a given volume of liquid gas provides, after evaporation, an approximately five times greater volume of gas phase. It follows that the restriction produced by such a limiter must be significant compared to that achieved in the expansion valve-evaporator. r.

C'est pourquoi, lorsque ces limiteurs sont constitués de matériau perméable et compressible traversé par le gaz, ils doivent être comprimés très fortement pour fournir une restriction de débit suffisante.This is why, when these limiters are made of permeable and compressible material through which the gas passes, they must be compressed very strongly to provide a sufficient flow restriction.

Certains de ces limiteurs de débit sont essentiellement constitués d'un matériau perméable, tel qu'une mèche, que l'on comprime radialement à l'aide d'un élément élastique sur lequel on exerce une contrainte axiale. Ces contraintes sont telles qu'au cours de l'utilisation du briquet, elles peuvent aller jusqu'à créer dans cet élément élastique des déformations irréversibles.Some of these flow limiters are essentially made of a permeable material, such as a wick, which is compressed radially using an elastic element on which an axial stress is exerted. These constraints are such that during the use of the lighter, they can go so far as to create irreversible deformations in this elastic element.

Celles-ci se traduisent par un relâchement de la compression exercée sur le matériau perméable, ce qui provoque une augmentation de la flamme maximale délivrée par le briquet, pouvant aller dans la pratique jusqu'à l'annulation des effets du limiteur de débit.These result in a relaxation of the compression exerted on the permeable material, which causes an increase in the maximum flame delivered by the lighter, which can go in practice up to the cancellation of the effects of the flow limiter.

La forte compression nécessaire dudit élément élastique entraîne une grande dureté du système de préréglage, qui en exclut pratiquement l'usage par un simple utilisateur et qui empêche celui-ci d'ajuster à sa guise etsuivantses besoins la flamme maximale qu'il désire obtenir.The high compression required of said elastic element results in great hardness of the presetting system, which practically excludes its use by a simple user and which prevents the latter from adjusting as desired and according to needs the maximum flame which he wishes to obtain.

La présente invention vise à éviter cet inconvénient, en proposant un briquet équipé d'un limiteur de débit du type précité, dans lequel ledit élément élastique ne nécessite pas de force de compression importante.The present invention aims to avoid this drawback, by proposing a lighter equipped with a flow limiter of the aforementioned type, in which said elastic element does not require significant compressive force.

Elle a par conséquent pour objet un briquet à gaz liquéfié comportant un dispositif détendeur-évaporateur, en amont duquel est disposé un dispositif limiteur de débit, caractérisé en ce que ledit dispositif limiteur de débit comprend un manchon déformable en un matériau perméable au gaz, une pièce rigide que gaine ledit manchon, un organe déformable élastiquement en contact avec une partie de la surface externe dudit manchon, et un moyen de préréglage apte à comprimer axialement ledit organe en vue de le déformer radialement en direction dudit manchon et de ladite pièce rigide.It therefore relates to a liquefied gas lighter comprising a pressure-reducing evaporator device, upstream of which is arranged a flow-limiting device, characterized in that said flow-limiting device comprises a deformable sleeve made of a material permeable to gas, a rigid part sheathed by said sleeve, an elastically deformable member in contact with a part of the external surface of said sleeve, and a presetting means capable of compressing said member axially in order to deform it radially in the direction of said sleeve and said rigid piece.

Dans une variante particulièrement intéressante de l'invention, l'élément rigide sur lequel est enfilé le manchon perméable déformable est le support de la rondelle perméable élastique constituant, de façon connue, le système détendeur-évaporateur.In a particularly advantageous variant of the invention, the rigid element on which is threaded the deformable permeable sleeve is the support for the elastic permeable washer constituting, in known manner, the expansion valve-evaporator system.

Ainsi, les deux dispositifs constituent un sous-ensemble, ce qui permet d'améliorer les opérations de montage et de maintenance du briquet.Thus, the two devices constitute a sub-assembly, which improves the assembly and maintenance operations of the lighter.

D'autre part, le fait que l'organe déformable élastiquement soit comprimé axialement et que les forces de compression qu'il exerce sur le manchon perméable soient orientées radialement permet de créer une démultiplication assurant une meilleure progressivité de cette compression et, donc, un contrôle plus précis du débit de gaz.On the other hand, the fact that the elastically deformable member is compressed axially and that the compression forces which it exerts on the permeable sleeve are oriented radially makes it possible to create a reduction ensuring a better progressiveness of this compression and, therefore, a more precise control of gas flow.

Plusieurs exemples de réalisation de l'invention seront décrits ci-après, en référence aux dessins annexés, dans lesquels:

  • la fig. 1 est une coupe d'une première réalisation de l'invention, dans laquelle le préréglage de la hauteur de flamme maximale et le réglage de flamme proprement dit sont réalisés à partir de la tête du briquet;
  • la fig. 2 représente une seconde réalisation de l'invention, dans laquelle le préréglage de la hauteur de flamme maximale est effectué à partir de la tête du briquet et le réglage de la flamme proprement dit est commandé à partir de la base de celui-ci;
  • la fig. 3 est une coupe d'une troisième variante de réalisation de l'invention, dans laquelle le préréglage de la hauteur de flamme maximale et le réglage de flamme proprement dit sont commandés à partir de la base du briquet.
Several embodiments of the invention will be described below, with reference to the accompanying drawings, in which:
  • fig. 1 is a section through a first embodiment of the invention, in which the presetting of the maximum flame height and the actual flame setting are carried out from the head of the lighter;
  • fig. 2 shows a second embodiment of the invention, in which the presetting of the maximum flame height is carried out from the head of the lighter and the adjustment of the flame itself is controlled from the base thereof;
  • fig. 3 is a section through a third alternative embodiment of the invention, in which the presetting of the maximum flame height and the actual flame setting are controlled from the base of the lighter.

Dans le cas de la fig. 1, le dispositif suivant l'invention est logé dans une cavité 1 du corps 2 du briquet, communiquant avec le réservoir du gaz (non représenté sur le dessin) par un passage 3.In the case of fig. 1, the device according to the invention is housed in a cavity 1 of the body 2 of the lighter, communicating with the gas tank (not shown in the drawing) by a passage 3.

Une pièce rigide cylindrique 4, entourée d'une mèche 5 en forme de manchon, est disposée dans une cuvette 6 creusée dans le fond de la cavité 1.A rigid cylindrical part 4, surrounded by a sleeve 5 in the form of a sleeve, is placed in a bowl 6 hollowed out in the bottom of the cavity 1.

Un joint torique 7, appliqué contre le fond de cette cavité 1 par une douille 8 vissée dans le corps 2 du briquet, comprime radialement le manchon 5.An O-ring 7, applied against the bottom of this cavity 1 by a socket 8 screwed into the body 2 of the lighter, radially compresses the sleeve 5.

La pièce rigide 4 est surmontée d'un plateau support 9 comportant un téton 10 en son centre. Une rondelle perméable élastique 11, reposant sur le plateau 9 coaxialement au téton 10, est comprimée par une seconde douille 12, vissée dans un tauradage de la douille 8. La partie inférieure de la douille 12 comporte un orifice 13, dans lequel est engagé le téton 10 et qui forme un passage pour le gaz. Un brûleur-clapet 14 est disposé dans un alésage de la douille 12.The rigid part 4 is surmounted by a support plate 9 comprising a stud 10 at its center. An elastic permeable washer 11, resting on the plate 9 coaxially with the stud 10, is compressed by a second sleeve 12, screwed into a sleeving of the sleeve 8. The lower part of the sleeve 12 has an orifice 13, in which the nipple 10 and which forms a passage for the gas. A valve burner 14 is placed in a bore of the bush 12.

L'opération de réglage de la hauteur de flamme se décompose en deux temps: dans un premier temps, on règle la hauteur maximale de la flamme que pourra produire le briquet, puis, dans un second temps, on ajuste la flamme à sa hauteur normale d'utilisation.The flame height adjustment operation is divided into two stages: firstly, the maximum height of the flame that the lighter can produce is adjusted, then, secondly, the flame is adjusted to its normal height of use.

Pour régler la hauteur maximale de ta flamme, on desserre tout d'abord la douille 12, de façon à décomprimer la rondelle perméable élastique 11, afin de réduire la perte de charge occasionnée par celle-ci.To adjust the maximum height of your flame, we first loosens the sleeve 12, so as to decompress the elastic permeable washer 11, in order to reduce the pressure drop caused by the latter.

On serre ensuite la douille 8 de manière à comprimer le joint torique 7, qui, en se déformant, comprime lui-même le manchon 5 contre la pièce rigide 4, en provoquant ainsi dans ce manchon la perte de charge correspondant à la flamme maximale désirée.The sleeve 8 is then tightened so as to compress the O-ring 7, which, when deformed, itself compresses the sleeve 5 against the rigid part 4, thereby causing in this sleeve the pressure drop corresponding to the maximum desired flame .

Compte tenu de ce que la mèche 5 est comprimée contre une pièce rigide, la force nécessaire pour créer l'étranglement est relativement faible. En conséquence, il en est de même de la déformation nécessaire du joint torique et donc de la force exercée sur celui-ci par la douille 8 pour provoquer sa déformation.Given that the wick 5 is compressed against a rigid part, the force necessary to create the constriction is relatively low. Consequently, the same is true of the necessary deformation of the O-ring and therefore of the force exerted on it by the sleeve 8 to cause its deformation.

Il est ainsi possible à un utilisateur de régler lui-même la hauteur de la flamme maximale fournie par son briquet en fonction des conditions particulières d'utilisation auxquelles il est soumis, par exemple les variations de température externes en cours de voyage.It is thus possible for a user to adjust himself the height of the maximum flame provided by his lighter as a function of the particular conditions of use to which he is subjected, for example the variations in external temperature during the journey.

Pour ajuster ensuite la flamme à la hauteur d'utilisation désirée, on serre la douille 12, de façon à comprimer la rondelle 11. On crée ainsi en aval du manchon 5 une perte de charge supplémentaire, qui diminue la flamme jusqu'à la hauteur d'utilisation désirée.To then adjust the flame to the desired height of use, the sleeve 12 is tightened, so as to compress the washer 11. This creates an additional pressure drop downstream of the sleeve 5, which decreases the flame to the height of desired use.

Dans la forme de réalisation de la fig. 2, le dispositif suivant l'invention est disposé dans un tube 20 fixé sur le corps 21 du briquet. L'intérieur du tube 20 comprend deux chambres 22 et 23, communiquant entre elles par un canal 24. Un élément support, constitué d'une tige cylindrique 25 surmontée d'un plateau 26, prend appui par sa base sur une vis de réglage 27 logée dans la chambre 22.In the embodiment of FIG. 2, the device according to the invention is arranged in a tube 20 fixed to the body 21 of the lighter. The interior of the tube 20 comprises two chambers 22 and 23, communicating with each other by a channel 24. A support element, consisting of a cylindrical rod 25 surmounted by a plate 26, is supported by its base on an adjustment screw 27 housed in room 22.

Un manchon 28 fait de mousse perméable est enfilé sur la tige 25 et est comprimé axialement par un joint torique 29, plus ou moins écrasé contre le fond de la chambre 23 par une vis de préréglage 30, avec interposition d'une rondelle rigide 31.A sleeve 28 made of permeable foam is threaded on the rod 25 and is compressed axially by an O-ring 29, more or less crushed against the bottom of the chamber 23 by a presetting screw 30, with the interposition of a rigid washer 31.

Le détendeur-évaporateur est constitué d'une rondelle perméable 32, disposée sur le plateau 25 et comprimée entre celui-ci et la vis 30. La tige 25, le plateau 26, le manchon 28 et la rondelle 32 constituent ainsi un sous-ensemble, facile à mettre en place dans le tube 20.The expansion valve-evaporator consists of a permeable washer 32, disposed on the plate 25 and compressed between the latter and the screw 30. The rod 25, the plate 26, the sleeve 28 and the washer 32 thus constitute a sub-assembly. , easy to install in the tube 20.

Un ressort 33, comprimé entre le fond 35 du tube 20 et une rondelle 37 solidaire de la tige 25, maintient celle-ci en butée contre la vis de réglage 27.A spring 33, compressed between the bottom 35 of the tube 20 and a washer 37 integral with the rod 25, maintains the latter in abutment against the adjusting screw 27.

Dans cet exemple de réalisation, le réglage de la hauteur de flamme maximale est réalisé à partir de la tête du briquet au moyen de la vis 30, alors que l'ajustement de la flamme à la hauteur d'utilisation désirée est obtenu à partir de la base du briquet, au moyen de la vis de réglage 27.In this exemplary embodiment, the adjustment of the maximum flame height is carried out from the lighter head by means of the screw 30, while the adjustment of the flame to the desired height of use is obtained from the base of the lighter, using the adjusting screw 27.

Cette disposition est rendue possible, de façon simple, en utilisant la pièce rigide constituée par la tige 25 pour transmettre l'effort de compression de la vis 27 au disque perméable 32.This arrangement is made possible, in a simple manner, by using the rigid part constituted by the rod 25 to transmit the compressive force of the screw 27 to the permeable disc 32.

Sur la fig. 3, pour faciliter les opérations de réglage, l'opération de préréglage de la hauteur de flamme maximale et l'opération de réglage de la flamme à la hauteur d'utilisation sont toutes deux réalisables à partir de la base du briquet.In fig. 3, to facilitate the adjustment operations, the operation for presetting the maximum flame height and the operation for adjusting the flame at the height of use are both achievable from the base of the lighter.

De plus, afin de rendre l'ensemble facilement interchangeable, le dispositif conforme à l'invention est logé dans un tube 40, dont la base 42 prend place dans un alésage 43 du fond 44 de celui-ci. Une douille 47 est vissée à l'intérieur du tube 40. Elle comporte une rainure 58 destinée à faciliter son entraînement en rotation. La face supérieure 48 de cette douille est percée axialement d'un trou 49, dans lequel est engagée de manière coulissante une tige support 50. Cette tige support est munie, à sa partie supérieure, d'un plateau 51 et prend appui, par son extrémité inférieure, contre une pièce de réglage 52, qui est vissée à l'intérieur de la douille 47 et qui est entraînée en rotation à l'aide d'un organe de commande 45, dont elle est rendue solidaire au moyen de cannelures 53 et d'une vis 46.In addition, in order to make the assembly easily interchangeable, the device according to the invention is housed in a tube 40, the base 42 of which takes place in a bore 43 in the bottom 44 thereof. A sleeve 47 is screwed inside the tube 40. It has a groove 58 intended to facilitate its driving in rotation. The upper face 48 of this socket is axially pierced with a hole 49, in which a support rod 50 is slidably engaged. This support rod is provided, at its upper part, with a plate 51 and is supported by its lower end, against an adjusting part 52, which is screwed inside the sleeve 47 and which is rotated by means of a control member 45, of which it is made integral by means of grooves 53 and a screw 46.

A l'extérieur de la douille 47, un manchon 54 en mousse perméable, servant de limiteur de débit, est enfilé sur la tige 50. Ce manchon 54 est serré radialement par un joint torique 55, entre deux rondelles rigides, dont l'une 56 prend appui contre le fond 48 de la douille 47, tandis que l'autre 57 prend appui contre un épaulement 59 du tube 40.Outside the sleeve 47, a sleeve 54 of permeable foam, serving as a flow limiter, is threaded on the rod 50. This sleeve 54 is tightened radially by an O-ring 55, between two rigid washers, one of which 56 bears against the bottom 48 of the socket 47, while the other 57 bears against a shoulder 59 of the tube 40.

Entre le plateau 51 et le fond 60 du tube 40 est interposée une rondelle 61 de matière perméable, servant de détendeur pour le briquet. Cette rondelle 61 est disposée coaxialement à un téton 62, qui fait saillie sur la face supérieure du plateau 51 et qui est engagé dans le canal 63 d'alimentation du brûleur du briquet.Between the plate 51 and the bottom 60 of the tube 40 is interposed a washer 61 of permeable material, serving as a regulator for the lighter. This washer 61 is arranged coaxially with a stud 62, which projects on the upper face of the plate 51 and which is engaged in the supply channel 63 of the lighter burner.

Pour réaliser le préréglage de la hauteur de flamme maximale, après avoir démonté l'organe de commande 45, on visse plus ou moins la douille 47, en s'aidant pour ce faire de la rainure 58, de façon à régler la compression du joint 55 et ainsi la perte de charge dans le manchon 54.To carry out the presetting of the maximum flame height, after having dismantled the control member 45, the socket 47 is more or less screwed in, using the groove 58 to do this, so as to adjust the compression of the joint. 55 and thus the pressure drop in the sleeve 54.

Pour ajuster la flamme à la hauteur d'utilisation désirée, on agit sur la pièce de réglage 52 par l'intermédiaire de l'organe de commande 45, de façon à comprimer plus ou moins, à l'aide de la tige 50 et du plateau 51, la rondelle perméable 61.To adjust the flame to the desired height of use, the adjusting part 52 is acted on by means of the control member 45, so as to compress more or less, using the rod 50 and the plate 51, the permeable washer 61.
