になされる。In this state, when the operating plate 9 to the magnet 12 move to the left in FIG. 2 due to a temperature change, the magnet 1
2 exerts a suction force on the ball valve body 5, and as the ball valve body 5 separates from the valve seat 2a, the ball valve body 4 comes into contact with the valve seat 1a, instantaneously switching the main pipe A from branch pipe B to C. Achieved in (Figure 3). Magnet 1 inside case 6
3.14 is not absolutely necessary, but if there is, the movement of the valve bodies 4 and 5 as the magnet 12 moves more reliably.

。。In the embodiment of FIGS. 5 and 6, a two-way valve is shown, one of the cylinders 2' having a flow passage 2' b at its outer circumference at its end.
is formed and a forest-like recess 2'a is formed inside it.
Therefore, the movement of the ball body 5' moving back and forth with respect to the recess 2'a and the accompanying opening/closing operation of the valve seat 1a by the ball valve body 4 are exactly the same as in the previous embodiment. .
