Abstract (en)
The mechanism has an ignition electrode (21) and flame detector (22), adjacent to the ignition burner (20). A control box (9) encloses a membrane (8) acting on a valve (6), admitting gas to the burner (3). The membrane forms two chambers (10,11) in the control box, one communicating with the gas admission chamber (2), upstream of the admission valve. A small valve (14), spring returned, communicates with the gas admission chamber (2,10), its operating coil (15) being controlled by an electronic circuit (23). This circuit also pilots the ignition burner, under control of the flame detector. An electromagnet (18) maintains the membrane in the open position, to admit gas to the burner, under control of the electronic circuit.

La membrane (8) du boîtier de commande est reliée, par l'intermédiaire de la tige de liaison et d'une pastille métallique (25) montée en bout de la tige, avec un embout magnétique (18) disposé sous le boîtier de commande, qui assure le maintien de ladite membrane en position d'ouverture du clapet d'admission gaz au brûleur, sous le contrôle du boîtier électronique (23). Application aux appareils sans veilleuse permanente. <IMAGE>
