Abstract:
1. A method for igniting a stream of gas with a system including an electronic control unit ( 5 ) and an ignition locking valve ( 17 ) having a valve disc ( 21 ) and an anchor ( 19 ) operatively connected to the valve disc ( 21 ), the method comprising the steps of: briefly energizing an electromagnet ( 11 ) by an electric pulse so that an actuating strut ( 10 ) engages the valve disc ( 21 ) to open the ignition locking valve ( 17 ) and position the anchor ( 19 ) adjacent an ignition locking magnet ( 18 ) connected to the electronic control unit, generating a holding current from an electricity source connected to the electronic control unit, and energizing the ignition locking magnet ( 18 ) with the holding current via the electronic control unit ( 5 ) before the stream of gas is ignited to hold the ignition locking valve ( 17 ) open when the anchor ( 19 ) is positioned adjacent the ignition locking magnet ( 18 ) by the actuating strut ( 10 ), maintaining the energization of the ignition locking magnet ( 18 ) with the holding current via the electronic control unit ( 5 ) until the stream of gas has been ignited or a defined holding period has been exceeded.
