Abstract

PURPOSE: To prevent unburned gas from flowing out, by expanding or contracting a thermal expander by the heat of a burner and shutting off a valve when the burner is extinguished.
CONSTITUTION: Valves 7, 14 are provided in parallel with each other in a casing 1 having a gas inlet pipe 16 and a gas outlet pipe 17 and are energized by springs 9, 15 in the direction to be closed. The valve stem 5 of the valve 7 is in contact with a cam 2 mounted on a timer shaft 3. The valve stem 13 of the valve 14 is in contact with the thermal expander 10. A heat receiver 11, which receives heat from the burner, is connected to the thermal expander 10. To ignite then burner, the valve 7 is opened for a predetermined time by a timer through the cam 2. When the burner is ignited, its heat expands the thermal expander 10, which the opens the valve 14, thereby continuing the combustion. To extinguish the burner, the thermal expander 10 is cooled and contracts, thereby closing the valve 14
