CA 2424612

A device (1) for the control of a burner (2) in general comprises an electrical control unit (7) for the lighting and automatic control of flame in the burner and a valve unit including: normally-closed valve means (5, 6) which are disposed in main line (3) for the supply of fuel to the burner (2) and can be opened by the control unit (7), means (14), controlled by the control unit (7), for automatically lighting the flame in the burner, and flame-detection means (17) associated with the burner and connected to the control unit (7). The device (1) also comprises actuator means (18) operatively associated with the control unit (7) and connected to the valve means (5, 6) for the manual operation thereof when the control unit (7) is deactivated owing to lack of electrical energy. When the control unit (7) is activated upon the return of the electrical energy, the actuator means (18) are relieved of the control of the valve means (5, 6).

L'invention concerne un dispositif (1) de commande d'un brûleur (2), comprenant une unité de commande électrique (7) pour l'allumage et la régulation automatique de la flamme dans le brûleur, et une unité de soupape comportant les élément suivants : des organes soupapes (5, 6), normalement fermés, disposés sur une ligne (3) principale d'alimentation du brûleur (2) en fuel et actionnés en ouverture par l'unité de commande (7) ; des moyens (14) pilotés par l'unité de commande (7) pour allumer automatiquement la flamme dans le brûleur ; des moyens de détection de flamme (17) associés au brûleur et reliés à l'unité de commande (7). Ce dispositif (1) comprend aussi des éléments actionneurs (18) couplés de manière fonctionnelle à l'unité de commande (7) et connectés aux organes soupapes (5, 6) pour être actionnés manuellement, lorsque l'unité de commande (7) est désactivée par suite d'une coupure de courant. Lorsque l'énergie électrique est à nouveau disponible et que l'unité de commande (7) est donc en service, les éléments actionneurs (18) ne sont plus commandés par les organes soupapes (5, 6).
