Description détaillée des dessinsDetailed description of the drawings

Les Figures 1 à 15 représentent un premier dispositif de connexion 2 d'appareil à gaz (non représenté). Par exemple, l'appareil à gaz peut être un réchaud simple feu ou une lampe.The Figures 1 to 15 represent a first gas appliance connection device 2 (not shown). For example, the gas appliance can be a single burner stove or a lamp.

Le dispositif de connexion 2 comporte un corps 4 et un injecteur 6. L'injecteur 6 est configuré pour être monté sur le corps 4 et en alternance démonté du corps 4. Par exemple, l'injecteur 6 est configuré pour être vissé au corps 4 et en alternance dévissé du corps 4. L'injecteur 6 est agencé pour être connecté fluidiquement à l'appareil à gaz et en alternance déconnecté fluidiquement de l'appareil à gaz. Ici, l'injecteur 6 débouche vers le haut.The connection device 2 comprises a body 4 and an injector 6. The injector 6 is configured to be mounted on the body 4 and alternately removed from the body 4. For example, the injector 6 is configured to be screwed to the body 4 and alternately unscrewed from the body 4. The injector 6 is arranged to be fluidly connected to the gas appliance and alternately fluidly disconnected from the gas appliance. Here, the injector 6 opens upwards.

Dans une configuration non représentée l'injecteur 6 est configuré pour être vissé au pousse valve 8 et en alternance dévissé du pousse valve 8. Dans cette configuration, l'appareil à gaz est configuré pour être vissé au pousse valve 8 et en alternance dévissé du pousse valve 8.In a configuration not shown the injector 6 is configured to be screwed to the valve pusher 8 and alternately unscrewed from the valve pusher 8. In this configuration, the gas appliance is configured to be screwed to the valve pusher 8 and alternately unscrewed from the push valve 8.

L'appareil à gaz est configuré pour être monté sur le dispositif de connexion 2 et en alternance démonté du dispositif de connexion 2. Ici, l'appareil à gaz est configuré pour être vissé sur le corps 4 et en alternance dévissé du corps 4.The gas appliance is configured to be mounted on the connection device 2 and alternately disassembled from the connection device 2. Here, the gas appliance is configured to be screwed onto the body 4 and alternately unscrewed from the body 4.

Le dispositif de connexion 2 comporte un pousse valve 8 (ou pousse clapet visible aux Figures 3, 6, 9 10 et 15). Le pousse valve 8 est configuré pour être monté sur le corps 4 et en alternance démonté du corps 4. Le pousse valve 8 est configuré pour être déplacé entre une position reculée ou position haute (visible aux Figures 3, 6 et 15) dans laquelle le pousse valve 8 est reculé pour permettre la fermeture d'un clapet 10a d'une cartouche de gaz 10 (visible à la Figure 15) et une position avancée maximum ou position basse (visible à la Figure 9) dans laquelle le pousse valve 8 est avancé pour permettre l'ouverture du clapet 10a de la cartouche de gaz 10 en passant par une pluralité de positions avancée intermédiaire. Le pousse valve 8 est configuré pour coulisser à l'intérieur du corps 4. Le pousse valve 8 est de forme tubulaire. Le pousse valve 8 comporte une première portion annulaire 8a et une seconde portion annulaire 8b dont la fonction sera apparente plus avant. En position reculée le pousse valve 8 est agencé pour être déconnecté fluidiquement à la cartouche de gaz 10. En position avancée maximum ou en position avancée intermédiaire le pousse valve 8 est agencé pour être connecté fluidiquement à la cartouche de gaz 10.The connection device 2 comprises a valve pusher 8 (or valve pusher visible to the Figure 3 , 6 , 9 10 and 15 ). The valve pusher 8 is configured to be mounted on the body 4 and alternately removed from the body 4. The valve pusher 8 is configured to be moved between a retracted position or a high position (visible to the Figure 3 , 6 and 15 ) in which the valve pusher 8 is moved back to allow the closure of a valve 10a of a gas cartridge 10 (visible in the Picture 15 ) and a maximum advanced position or low position (visible at the Figure 9 ) in which the valve pusher 8 is advanced to allow the opening of the valve 10a of the gas cartridge 10 through a plurality of intermediate advanced positions. The valve pusher 8 is configured to slide inside the body 4. The valve pusher 8 is tubular in shape. The valve pusher 8 comprises a first annular portion 8a and a second annular portion 8b whose function will be apparent later. In the retracted position the valve pusher 8 is arranged to be fluidly disconnected from the gas cartridge 10. In position maximum advanced or in the intermediate advanced position the valve pusher 8 is arranged to be fluidically connected to the gas cartridge 10.

La cartouche de gaz 10 (visible à la Figure 15) comporte une valve. La valve comporte le clapet 10a, un siège 10b (ou joint) et un organe de rappel élastique (non représenté) rappelant le clapet 10a vers le siège 10b. Le clapet 10a comporte une paroi de fond 10c. Le clapet 10a comporte un croisillon 10d agencé sur la paroi de fond 10c pour permettre de maintenir une distance entre pousse valve 8 et la paroi de fond 10c du clapet 10a lorsque le pousse valve 8 est en position avancée (visible à la Figure 9). La cartouche de gaz 10 comporte également une collerette 10f.The gas cartridge 10 (visible on the Picture 15 ) has a valve. The valve comprises the valve 10a, a seat 10b (or seal) and an elastic return member (not shown) recalling the valve 10a towards the seat 10b. The valve 10a has a bottom wall 10c. The valve 10a comprises a crosspiece 10d arranged on the bottom wall 10c to make it possible to maintain a distance between the valve pusher 8 and the bottom wall 10c of the valve 10a when the valve pusher 8 is in the advanced position (visible at the Picture 9 ). The gas cartridge 10 also includes a collar 10f.

Lorsque le pousse valve 8 est en position reculée (visible aux Figures 3, 6 et 15), l'organe de rappel élastique repousse le clapet 10a dans la direction du siège 10b. Le clapet 10a est en contact avec le siège 10b et le gaz contenu par la cartouche de gaz 10 ne peut s'écouler entre le clapet 10a et le siège 10b et par conséquent ne peut s'écouler de l'extérieur du clapet 10a vers l'intérieur du clapet 10a.When the valve pusher 8 is in the retracted position (visible to Figure 3 , 6 and 15 ), the elastic return member pushes the valve 10a in the direction of the seat 10b. The valve 10a is in contact with the seat 10b and the gas contained by the gas cartridge 10 cannot flow between the valve 10a and the seat 10b and therefore cannot flow from the outside of the valve 10a towards the inside the valve 10a.

Lorsque le pousse valve 8 est en position avancée maximum (visible à la Figure 9) ou en position avancée intermédiaire, le pousse valve 8 repousse le clapet 10a dans la direction opposée au siège 10b. Le clapet 10a est distante du siège 10b et le gaz contenu par la cartouche de gaz 10 peut s'écouler entre le clapet 10a et le siège 10b. Le pousse valve 8 est en contact avec le croisillon 10d et est ainsi distant de la paroi de fond 10c du clapet 10a. Le pousse valve 8 est également distant de la paroi latérale 10e du clapet 10a. Ainsi, lorsque le pousse valve 8 est en position avancée maximum ou en position avancée intermédiaire le gaz contenu par la cartouche de gaz 10 peut s'écouler de l'intérieur du clapet 10a vers l'intérieur du pousse valve 8.When the valve pusher 8 is in the maximum advanced position (visible on the Figure 9 ) or in the intermediate advanced position, the valve pusher 8 pushes the valve 10a in the direction opposite to the seat 10b. The valve 10a is remote from the seat 10b and the gas contained by the gas cartridge 10 can flow between the valve 10a and the seat 10b. The valve pusher 8 is in contact with the spider 10d and is thus distant from the bottom wall 10c of the valve 10a. The valve pusher 8 is also remote from the side wall 10e of the valve 10a. Thus, when the valve pusher 8 is in the maximum advanced position or in the intermediate advanced position, the gas contained by the gas cartridge 10 can flow from the inside of the valve 10a towards the inside of the valve pusher 8.

Le dispositif de connexion 2 comporte un organe de commande 12. L'organe de commande 12 est configuré pour être monté sur le corps 4 et en alternance démonté du corps 4. L'organe de commande 12 est configuré pour être déplacé entre une position de fermeture (visible aux Figures 1 à 6 et 12 à 15) et une position d'ouverture maximum (visible aux Figures 7 à 9) en passant par une pluralité de positions d'ouverture intermédiaire. En position de fermeture l'organe de commande 12 déplace le pousse valve 8 en position reculée (visible aux Figures 3, 6 et 15). En position d'ouverture maximum l'organe de commande 12 déplace le pousse 8 valve en position avancée maximum (visible à la Figure 9). En position d'ouverture intermédiaire l'organe de commande 12 déplace le pousse 8 valve en position avancée intermédiaire.The connection device 2 comprises a control member 12. The control member 12 is configured to be mounted on the body 4 and alternately removed from the body 4. The control member 12 is configured to be moved between a position of closure (visible to Figures 1 to 6 and 12 to 15 ) and a maximum open position (visible to Figures 7 to 9 ) passing through a plurality of intermediate opening positions. In the closed position, the control member 12 moves the valve pusher 8 to the retracted position (visible to the Figure 3 , 6 and 15 ). In the maximum open position, the control member 12 moves the valve pusher 8 into position maximum advance (visible at Figure 9 ). In the intermediate open position, the control member 12 moves the valve pusher 8 to the intermediate advanced position.

Le pousse valve 8 et l'organe de commande 12 sont configurés de sorte que lorsque l'organe de commande 12 est déplacé entre la position de fermeture (visible aux Figures 1 à 6 et 12 à 15) et une première position d'ouverture intermédiaire (visible à la Figure 11) le pousse valve 8 demeure en position reculée. Ainsi, le dispositif de connexion 2 permet de rattraper les tolérances industrielles et assure que la connexion fluidique ne soit pas réalisée entre le pousse valve 8 et la cartouche de gaz 10 lorsque l'organe de commande 12 est déplacé entre la position de fermeture (visible aux Figures 1 à 6 et 12 à 15) et la première position d'ouverture intermédiaire (visible à la Figure 11).The valve pusher 8 and the control member 12 are configured so that when the control member 12 is moved between the closed position (visible to Figures 1 to 6 and 12 to 15 ) and a first intermediate open position (visible at the Picture 11 ) the valve pusher 8 remains in the retracted position. Thus, the connection device 2 makes it possible to catch up with industrial tolerances and ensures that the fluidic connection is not made between the valve pusher 8 and the gas cartridge 10 when the control member 12 is moved between the closed position (visible to Figures 1 to 6 and 12 to 15 ) and the first intermediate open position (visible on the Picture 11 ).

Le pousse valve 8 et l'organe de commande 12 sont configurés de sorte que lorsque l'organe de commande 12 est déplacé entre la première position d'ouverture intermédiaire (visible à la Figure 11) et une seconde position d'ouverture intermédiaire (non représentée) avec un pas fixe le pousse valve 8 est déplacé entre la position reculée (visible aux Figures 3, 6 et 15) et une position avancée intermédiaire (non représentée) avec un pas variable.The valve pusher 8 and the control member 12 are configured so that when the control member 12 is moved between the first intermediate opening position (visible at Picture 11 ) and a second intermediate opening position (not shown) with a fixed pitch the valve pusher 8 is moved between the retracted position (visible to Figure 3 , 6 and 15 ) and an intermediate advanced position (not shown) with a variable pitch.

Le pousse valve 8 et l'organe de commande 12 sont configurés de sorte que lorsque l'organe de commande 12 est déplacé entre la seconde position d'ouverture intermédiaire (non représentée) et la position d'ouverture maximum (visible aux Figures 7 à 9) avec un pas fixe, le pousse valve 8 est déplacé entre la position avancée intermédiaire (non représentée) et la position avancée maximum (visible à la Figure 9) avec un pas fixe ou variable.The valve pusher 8 and the control member 12 are configured so that when the control member 12 is moved between the second intermediate open position (not shown) and the maximum open position (visible to Figures 7 to 9 ) with a fixed pitch, the valve pusher 8 is moved between the intermediate forward position (not shown) and the maximum forward position (visible in Picture 9 ) with a fixed or variable pitch.

Lorsque l'organe de commande est déplacé entre la première position d'ouverture intermédiaire (visible à la Figure 11) et la seconde position d'ouverture intermédiaire (non représentée) le pousse valve 8 est connecté fluidiquement à la cartouche de gaz 10. L'ouverture du clapet 10a de la cartouche de gaz 10 croît (par exemple non-linéairement ou sinusoïdalement). Le débit de gaz circulant à travers le clapet 10a de la cartouche de gaz 10 croît (par exemple non-linéairement ou sinusoïdalement).When the control member is moved between the first intermediate opening position (visible on the Picture 11 ) and the second intermediate opening position (not shown) the valve pusher 8 is fluidly connected to the gas cartridge 10. The opening of the valve 10a of the gas cartridge 10 increases (for example non-linearly or sinusoidally). The flow of gas circulating through the valve 10a of the gas cartridge 10 increases (for example non-linearly or sinusoidally).

Lorsque l'organe de commande 12 est déplacé entre la seconde position d'ouverture intermédiaire (non représentée) et la position d'ouverture maximum (visible aux Figures 7 à 9) le pousse valve 8 est toujours connecté fluidiquement à la cartouche de gaz. L'ouverture du clapet 10a de la cartouche de gaz 10 croît (par exemple linéairement ou sinusoïdalement) jusqu'à atteindre une ouverture maximale. Le débit de gaz circulant à travers le clapet 10a de la cartouche de gaz 10 croît (par exemple linéairement ou sinusoïdalement) jusqu'à atteindre un débit maximal (plein débit). Ainsi, le réglage du débit de gaz entre la cartouche de gaz 10 et l'appareil à gaz peut être facilité.When the control member 12 is moved between the second intermediate open position (not shown) and the maximum open position (visible in Figures 7 to 9 ) the valve pusher 8 is still fluidly connected to the gas cartridge. The opening of the valve 10a of the gas cartridge 10 increases (for example linearly or sinusoidally) until reaching a maximum opening. The flow of gas circulating through the valve 10a of the gas cartridge 10 increases (for example linearly or sinusoidally) until it reaches a maximum flow (full flow). Thus, the adjustment of the gas flow between the gas cartridge 10 and the gas appliance can be facilitated.

Ici, l'organe de commande 12 comporte un arbre à came 12a, une came 12b montée à une première extrémité de l'arbre à came 12a et un bouton de réglage 12c (ou volant) monté à une seconde extrémité de l'arbre à came 12a. La came 12b est agencée pour prendre appui sur le pousse valve 8. Ici, la came 12b est agencée pour être reçue entre la première portion annulaire 8a et la seconde portion annulaire 8b du pousse valve 8. La came 12b est agencée pour prendre appui sur la seconde portion annulaire 8b lorsque l'organe de commande 12 est déplacé de la position de fermeture (visible aux Figures 1 à 6 et 12 à 15) à la position d'ouverture maximum (visible aux Figures 7 à 9). La came 12b est agencée pour prendre appui sur la première portion annulaire 8a lorsque l'organe de commande 12 est déplacé de la position d'ouverture maximum (visible aux Figures 7 à 9) à la position de fermeture (visible aux Figures 1 à 6 et 12 à 15). Le pas du pousse valve 8 est défini par la forme du pousse valve 8 et/ou de la came 12b. Ici, le bouton de réglage 12c est agencé pour être tourné au moins entre 0 et 180 degrés. La première position d'ouverture intermédiaire (visible à la Figure 11) est située entre 20 et 100 degrés. La seconde position d'ouverture intermédiaire (non représentée) est située entre 105 et 180 degrés. Il est entendu que d'autres plages de valeurs sont possibles.Here, the control member 12 comprises a camshaft 12a, a cam 12b mounted at a first end of the camshaft 12a and an adjustment knob 12c (or flywheel) mounted at a second end of the camshaft. cam 12a. Cam 12b is arranged to bear against valve pusher 8. Here, cam 12b is arranged to be received between first annular portion 8a and second annular portion 8b of valve pusher 8. Cam 12b is arranged to bear against the second annular portion 8b when the control member 12 is moved from the closed position (visible to the Figures 1 to 6 and 12 to 15 ) to the maximum open position (visible to Figures 7 to 9 ). The cam 12b is arranged to bear against the first annular portion 8a when the control member 12 is moved from the maximum open position (visible to Figures 7 to 9 ) to the closed position (visible on Figures 1 to 6 and 12 to 15 ). The pitch of the valve pusher 8 is defined by the shape of the valve pusher 8 and/or of the cam 12b. Here, the adjustment knob 12c is arranged to be turned at least between 0 and 180 degrees. The first intermediate open position (visible on the Picture 11 ) is between 20 and 100 degrees. The second intermediate opening position (not shown) is located between 105 and 180 degrees. It is understood that other ranges of values are possible.

L'organe de l'organe de commande 12 est monté sur le corps 4, par exemple par une vis sans tête 13 reçu dans un alésage du corps 4 et une rainure semi-circulaire de la came 12b.The member of the control member 12 is mounted on the body 4, for example by a grub screw 13 received in a bore of the body 4 and a semi-circular groove of the cam 12b.

La course de l'organe de commande 12 entre la première position de fermeture et la position d'ouverture maximum est longue (typiquement 180 degrés). En revanche, la course du pousse valve 8 entre la position reculée et la position avancée maximum est très courte (typiquement de l'ordre de 1mm). Aussi, il peut être difficile de convertir la longue course de l'organe de commande 12 en la courte course du pousse valve 8 et peut être difficile d'ajuster finement la position du pousse valve 8, l'ouverture du clapet 10a et le débit de gaz de la cartouche de gaz.The stroke of the control member 12 between the first closed position and the maximum open position is long (typically 180 degrees). On the other hand, the stroke of the valve pusher 8 between the retracted position and the maximum advanced position is very short (typically of the order of 1 mm). Also, it can be difficult to convert the long stroke of the control member 12 into the short stroke of the valve pusher 8 and can be difficult to finely adjust the position of the valve pusher 8, the opening of the valve 10a and the flow rate. of gas from the gas cartridge.

Une solution à ce problème pourrait être d'ajuster finement la forme de la came 12b. Toutefois les tolérances industrielles requises serait trop faible (typiquement de l'ordre du centième de millimètre) et les couts afférents seraient manifestement trop importants au vu de l'objectif visé.A solution to this problem could be to fine tune the shape of the cam 12b. However, the industrial tolerances required would be too low (typically of the order of a hundredth of a millimeter) and the related costs would obviously be too high in view of the objective sought.

Une solution alternative à ce problème est décrite plus loin en référence aux Figures 20 à 29 et propose de modifier la cartouche de gaz 10 plutôt que de se concentrer sur la forme de la came 12b.An alternative solution to this problem is described later with reference to Figures 20 to 29 and proposes to modify the gas cartridge 10 rather than focusing on the shape of the cam 12b.

Le dispositif de connexion 2 comporte un organe de verrouillage 14 (visible aux Figures 3, 6, 9 et 10) configuré pour être déplacé entre une position déverrouillée (visible à la Figure 3) et une position verrouillée (visible aux Figures 6, 9 et 15). Lorsque l'organe de verrouillage 14 est en position verrouillée (visible aux Figures 6, 9 et 15) l'organe de verrouillage 14 verrouille le dispositif de connexion 2 à la cartouche de gaz 10. Lorsque l'organe de verrouillage 14 est en position déverrouillée (visible à la Figure 3) l'organe de verrouillage déverrouille le dispositif de connexion 2 à la cartouche de gaz. L'organe de verrouillage 14 est monté sur le corps 4, par exemple par des vis 15 reçues à travers des orifices de l'organe de verrouillage 14 et des alésages du corps 4.The connection device 2 comprises a locking member 14 (visible to Figure 3 , 6 , 9 and 10 ) configured to be moved between an unlocked position (visible at the Figure 3 ) and a locked position (visible to Figure 6 , 9 and 15 ). When the locking member 14 is in the locked position (visible to Figure 6 , 9 and 15 ) the locking member 14 locks the connection device 2 to the gas cartridge 10. When the locking member 14 is in the unlocked position (visible in Figure 3 ) the locking member unlocks the connection device 2 to the gas cartridge. The locking member 14 is mounted on the body 4, for example by screws 15 received through holes in the locking member 14 and bores in the body 4.

Ici, l'organe de verrouillage 14 comporte une bague comprenant des pattes. Les pattes s'étendent longitudinalement (c'est-à-dire s'étendant selon un axe parallèle à l'axe du pousse valve 8). Les pattes sont élastiquement déformables radialement (c'est-à-dire sont élastiquement déformables ou déplaçables selon un plan perpendiculaire à l'axe du pousse valve 8).Here, the locking member 14 comprises a ring comprising lugs. The legs extend longitudinally (that is to say extending along an axis parallel to the axis of the valve pusher 8).
