Claims

[Scope of utility model registration request]

a high-temperature valve seat 5 that communicates and blocks communication between the high-temperature flow path 6 and the mixing chamber 2;
a low-temperature valve seat 3 that connects and disconnects the low-temperature flow path 4 and the mixing chamber 2;
A high temperature fluid control valve 8, a low temperature fluid control valve 7 corresponding to each valve seat, a first spring 9 that biases the high temperature fluid control valve 8 in a direction away from the high temperature valve seat 5, and a low temperature fluid control valve 7. Second spring 10 biased in the direction of pressing against the low temperature valve seat
and a driving body 11 made of a shape memory alloy and disposed between the high temperature fluid control valve 8 and the low temperature fluid control valve 7, and the spring force of the driving body 11 is reduced below a certain temperature. <Resilient force of the first spring 9 <The second spring 1
A control valve characterized in that the spring force of the driving body 11 is set to 0 and the spring force of the driving body 11 is made larger than the spring force of the first and second springs 9 and 10 at a certain temperature or higher.
