Sur la figure 1, le boîtier est constitué d'une pièce 4 et d'un capot 29.In FIG. 1, the housing consists of a part 4 and a cover 29.

La pièce 4 monobloc, est réalisée à partir d'un profilé en aluminium coupé à longueur et comprend deux conduits parallèles 5 et 6 cloisonnés par des bouchons étanches 9, 10, 11, 12 et 13, afin d'obtenir la chambre de sécurité 14, la chambre intermédiaire 15, la chambre de régulation 16 et la chambre de distribution 17 (nourrice).The one-piece part 4 is produced from an aluminum profile cut to length and comprises two parallel conduits 5 and 6 partitioned by watertight plugs 9, 10, 11, 12 and 13, in order to obtain the safety chamber 14 , the intermediate chamber 15, the regulation chamber 16 and the distribution chamber 17 (feeder).

Le capot 29 comporte des rainures 3 pour le montage d'une carte électronique 30 portant les circuits de commande des différentes vannes et porte sur sa face supérieure le tableau de commande 36 de l'appareil avec, notamment, les boutons de manoeuvre 31.The cover 29 has grooves 3 for mounting an electronic card 30 carrying the control circuits of the various valves and carries on its upper face the control panel 36 of the device with, in particular, the operating buttons 31.

Le gaz arrive par le raccord 8 et pénètre dans la chambre 14 où se trouve le clapet 7 de sécurité commandé par la vanne de sécurité 20, ce clapet étant en position fermée lorsque l'appareil est arrêté ou en sécurité et en position ouverte lorsque l'appareil fonctionne normalement.The gas arrives through the connector 8 and enters the chamber 14 where the safety valve 7 controlled by the safety valve 20 is located, this valve being in the closed position when the appliance is stopped or in safety and in the open position when the the device is operating normally.

En cours de fonctionnement, le gaz pénètre, à travers l'orifice 18, dans la chambre 15, puis, à travers l'orifice 19, dans la chambre 16 où se trouvent les clapets de régulation 21 et 22, actionnés respectivement par les vannes 23 et 24, celles-ci étant en position ouverte ou fermée suivant la demande. Lorsque l'un des clapets 21 ou 22 est ouvert, ou les deux, le gaz pénètre, à travers l'un ou l'autre des orifices 25 ou 26 ou à travers les deux, dans la chambre de distribution 17 sur laquelle sont montés des injecteurs 27 qui assureront l'alimentation du gaz aux brûleurs.During operation, the gas penetrates, through the orifice 18, into the chamber 15, then, through the orifice 19, into the chamber 16 where the regulating valves 21 and 22 are located, actuated respectively by the valves 23 and 24, these being in the open or closed position depending on demand. When one or both of the valves 21 or 22 is open, the gas penetrates, through one or the other of the orifices 25 or 26 or through both, into the distribution chamber 17 on which are mounted injectors 27 which will supply the gas to the burners.

La figure 2 illustre la fonction de sécurité qui est réalisée par la vanne de sécurité 20, qui peut être de type électrovanne ou vanne thermoélectrique ou tout autre moyen permettant d'assurer la fonction de sécurité et qui commande le clapet de sécurité 7 qui ouvre ou ferme l'orifice 18 permettant le passage du gaz dans les autres chambres.FIG. 2 illustrates the safety function which is carried out by the safety valve 20, which can be of the solenoid or thermoelectric valve type or any other means making it possible to ensure the safety function and which controls the safety valve 7 which opens or closes orifice 18 allowing gas to pass into the other chambers.

La figure 3 illustre la fonction de régulation qui est réalisée par les vannes de régulation 23 24, qui peuvent être du type électrovannes tout ou rien ou modulantes ou tout autre moyen permettant de réaliser la fonction de régulation et qui commandent les clapets 21 et 22 qui ouvrent ou ferment les orifices 25 et 26 permettant le passage du gaz dans la chambre de distribution 17.FIG. 3 illustrates the regulating function which is carried out by the regulating valves 23 24, which can be of the all-or-nothing or modulating solenoid type or any other means making it possible to carry out the regulating function and which control the valves 21 and 22 which open or close the orifices 25 and 26 allowing the passage of gas in the distribution chamber 17.

La figure 4 illustre la fonction de distribution réalisée par la chambre 17 qui porte les injecteurs 27 assurant l'alimentation du gaz aux brûleurs.Figure 4 illustrates the distribution function performed by the chamber 17 which carries the injectors 27 ensuring the supply of gas to the burners.

La figure 5 est une coupe de la pièce profilée 4 et montre les conduits 5 et 6. A sa partie supérieure, deux rainures 28 permettent de recevoir le capot 29.FIG. 5 is a section of the profiled part 4 and shows the conduits 5 and 6. At its upper part, two grooves 28 make it possible to receive the cover 29.

Il est entendu que l'on peut, sans sortir de l'invention, modifier des détails de réalisation ou leur arrangement en vue d'obtenir un même résultat ainsi qu'il apparait au vu de la variante illustrée par les figures 6 à 10.It is understood that it is possible, without departing from the invention, to modify construction details or their arrangement with a view to obtaining the same result as appears from the variant illustrated in FIGS. 6 to 10.

Le boîtier 43 de la figure 6 se compose d'un corps de boîtier 32 et d'un couvercle 33, le corps de boîtier comportant, à sa partie inférieure, un conduit de gaz 34, et à sa partie supérieure, deux rainures 35 recevant une carte électronique 44 portant les circuits de commande des différentes vannes.The housing 43 of FIG. 6 consists of a housing body 32 and a cover 33, the housing body comprising, at its lower part, a gas conduit 34, and at its upper part, two grooves 35 receiving an electronic card 44 carrying the control circuits of the various valves.

Pour assurer les fonctions de sécurité et de régulation et éventuellement même de distribution avec un seul conduit, on utilise un porte-siège de clapet 37 de forme particulière illustrée par les figures 7, 8 et 9, la figure 7 étant une vue extérieure de ce porte-siège, la figure 8, une coupe suivant la ligne VIII-VIII de la figure 7 et la figure 9, une coupe suivant IX-IX de la figure 8.To ensure the safety and regulation functions and possibly even distribution with a single duct, use is made of a valve seat carrier 37 of particular shape illustrated by FIGS. 7, 8 and 9, FIG. 7 being an external view of this seat carrier, Figure 8, a section along line VIII-VIII of Figure 7 and Figure 9, a section along IX-IX of Figure 8.

Ce porte-siège de clapet se présente sous la forme d'un cylindre creux, avec une cloison médiane transversale 38 qui porte le siège de clapet proprement dit 39 avec son orifice 40, les deux parties cylindriques situées de part et d'autre de la cloison 38 comportant deux évidements 41 et 42 mais diamétralement opposés l'un à l'autre.This valve seat holder is in the form of a hollow cylinder, with a transverse central partition 38 which carries the valve seat itself 39 with its orifice 40, the two cylindrical parts located on either side of the partition 38 having two recesses 41 and 42 but diametrically opposite one another.

Il est monté étanche sur le corps du conduit qu'il dessert, en l'occurrence par collage, dans un alésage d'un diamètre plus grand que celui du conduit de gaz 34, de manière que le gaz contenu dans la partie du conduit située côté de l'évidement 41 ne puisse passer dans celle située du côté de l'évidement 42 que par l'orifice 40 et donc en être isolé lorsque l'orifice 40 est fermé (voir figure 10).It is mounted leaktight on the body of the duct which it serves, in this case by gluing, in a bore with a diameter larger than that of the gas duct 34, so that the gas contained in the part of the duct situated side of recess 41 cannot pass into that located on the side of the recess 42 only through the orifice 40 and therefore be isolated from it when the orifice 40 is closed (see FIG. 10).

On peut ainsi avoir sur le même et unique conduit les trois fonctions de sécurité, de régulation et de distribution, quel que soit le nombre de vannes utilisées.It is thus possible to have the three safety, regulation and distribution functions on the same single line, regardless of the number of valves used.
