Abstract (en)

Improvements on instant lighting devices in built-in safety valves used in gas appliances; particularly in house hold appliances with one or more burners. Each of these devices includes a printed circuit (2) equipped with a selector (5) for the feed by means of a trigger (6), to a valve which controls the flow of gas to the burner once an external button (3) is pressed. The burner is lit by means of time delay (10) or flame ionization, and at the same instant an auxiliary current supply to the magnetic group of the valve is produced. This current is timed, and it replaces the electrical current generated by a thermocouple (4) when it is heated by the flame of the burner.
