PURPOSE:To improve operability and durability by conducting a liquid below a set temperature of a spring made of a shape memory alloy to the first outflow port, and a liquid above the set temperature to the second outflow port. CONSTITUTION:When the temperature of a liquid entering an inflow port 2 is lower than a set temperature, a working body 6 is pressed by a spring 7 to close the second outflow port 5 and open the first outflow port 3, whereby the outflow port 3 and the inflow port 2 are connected to each other. When the temperature of a liquid is higher than the set temperature, the working body 6 is pressed by a spring 8 made of a shape memory alloy, which is heated by warming heat to generate strong spring force, thereby to close the first outer port 3 and open the second outflow port 5, so that the liquid is guided to a specified passage through the second outflow port 5. |
