Claims

[Scope of utility model registration request]

A valve is slidably inserted into a valve hole of a valve body having a fluid inlet port and an outlet port, and is pressed against a valve seat of the valve hole by a spring, and one end is fixed to one end on the axis of the valve and the other end is A tension rod that protrudes through an end cover that closes the other end of the valve hole, a cylindrical rod case that has its end fixed to the end cover and surrounds the tension rod leaving a free end, and a free end of the tension rod. A thermovalve that controls flow rate in response to temperature changes, characterized by comprising a spring made of a shape memory alloy and whose pressing force changes depending on temperature changes, which is attached between a pair of plate washers fixed to the end of a rod case. .
