  • Spark ignition system with positive suppression of spark when pilot flame is sensed
    Patent number: 4689006
    Abstract: A spark ignition system for a pilot flame uses a flame sensing rod to switch ac voltage from a spark generator to a main valve, thereby providing positive suppression of spark generation once the pilot flame is sensed. A main oscillator activated by a flame sensing signal is provided to operate a switch for this purpose. Should the pilot flame be extinguished, the switch automatically reverts to its first state, thereby closing the main valve and reactivating the spark generator. The entire system is operative only when ac voltage is present from a thermostat demanding heat. The pilot valve connected directly to the thermostat is open to emit gas whenever there is a demand for heat.
