- Figures 6 to 10 illustrate another embodiment of the invention.
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
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 includes two
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
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
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

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 performed by the regulating
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
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
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
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
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
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
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.
