The spring 50 urges the safety valve member 48 toward the safety valve port 49. Other configurations are the same as those in the first embodiment.

When the fuel gas is supplied from the fuel tank 1, the fuel gas passes through the center of the temperature-sensitive ferrite 37 and passes through the gap 42 between the temperature-sensitive ferrite 37, the magnet 39, and the valve holder 41. After passing through, it reaches the valve port 45 and blows out from the nozzle 30. At this time, the air is drawn in from the intake hole 51 by the flow rate of the fuel gas, and becomes a mixture of the fuel gas and the air and is supplied to the catalyst 33.

When the heater 36 is energized and glows red, a flame is reliably generated on the heater 36 side of the catalyst 33, and the metal net 52 glows red. Thereby, the catalyst 33

When the temperature-sensitive ferrite 37 fixed to the outer shell 38 is heated, and the temperature of the temperature-sensitive ferrite 37 reaches the Curie point determined by the composition, the magnet 39 can no longer adsorb the temperature-sensitive ferrite 37, and The valve member 40 moves to the valve body 44 side to close the valve port 45. As a result, the fuel gas is no longer supplied to the catalyst 33, and the temperature decreases.

The temperature-sensitive ferrite 37 has a very small hysteresis and returns to the original state when the temperature changes by several degrees or less.
When the temperature-sensitive ferrite 37 returns, the magnet 39 attracts the temperature-sensitive ferrite 37 again and opens the valve port 45. Since the temperature of the catalyst 33 is sufficiently high during this time, the catalytic reaction starts again when the fuel gas is supplied. By repeating this operation, the temperature of the case 34 can be kept constant.

At this time, the control temperature is the temperature-sensitive ferrite 3
7, the temperature controller 32 made of the temperature-sensitive ferrite 37 having the same composition can control the temperature at the same temperature, and does not require adjustment at the time of assembly. For this reason, mass production becomes very easy. In addition, when it is desired to change the set temperature, a temperature-sensitive ferrite 37 having a predetermined composition may be combined, which can be performed very easily.

Even if the temperature of the temperature-sensitive ferrite 37 reaches the Curie point, the valve port 45 cannot be closed for some reason, and if the fuel gas continues to be supplied, the temperature of the heat fusible material 46 will decrease. When the temperature reaches 221 ° C., the heat fusible body 46 melts, and the spring force of the spring 50 presses the safety valve member 48 against the safety valve port 49, whereby the fuel gas is released from the catalyst 33.
And the safety can be ensured.
