PROBLEM TO BE SOLVED: To provide a selector valve capable of selecting a flow path depending on the temperature of en external object.SOLUTION: A selector valve includes a valve body 1 which has three inlet/outlet ports 3, 4, 5, and a valve element 9 which is displaced in the valve body 1 depending on a temperature detected by a temperature detecting part mounted on the valve body 1 to selectively close one of the two outflow inlets 4, 5 out of the three inlet/outlet ports 3, 4, 5. Herein, a wax element 14 is mounted on the valve body 1. The wax element 14 has a wax to be expanded/contracted depending on the temperature, and a piston 16 to be moved forward/backward with the expansion/contraction of the wax. With the forward/backward movement of the piston 16, the valve element 9 urged by a return spring 20 is moved in the valve body 1 to open/close the inlet/outlet ports 4, 5. A wax storage part of the wax element 14 constitutes the temperature detecting part, is protruded from the valve body 1 and is exposed to the outside of the valve body 1. |
