Abstract

L'invention concerne un procédé et un circuit permettant d'allumer un flux de gaz de manière entièrement automatique. L'objectif de cette invention est de maintenir la consommation de courant nécessaire à l'allumage à un niveau si faible qu'une source de tension intégrable peut être utilisée. A cet effet, après l'activation d'une unité de commande électronique, une soupape de sécurité d'allumage thermoélectrique (2) est ouverte par l'intermédiaire d'un électroaimant (5) qui est excité momentanément par une impulsion de courant et maintenue en position ouverte par l'intermédiaire d'aimants de sécurité d'allumage (6), au moyen d'un courant de maintien fourni par une source de tension (10), et le gaz qui s'écoule est allumé. Dès qu'un élément thermique (4) a fourni le courant de maintien nécessaire, la source de tension (10) est mise hors circuit. En cas de panne, le procédé selon l'invention est automatiquement interrompu.
