  • Device for automatic reignition of an extinguished burner flame
    Patent number: 5403183
    Abstract: A device for automatic reignition of an extinguished gas flame in a burner. The burner (10) is connected to a gas source via a security valve (13) operated to its closed position by the action of spring means. By magnetic means the security valve can be kept in its open position under the influence of the EMF generated by a thermocouple (25) heated by the gas flame. An igniter (20,21) is activated by an electronic control arrangement (22) upon the latter detecting changes of a predetermined rate of change in the EMF generated by the thermocouple.
