弁。 Between the case and the valve body that is loosely inserted into the valve chamber of the case and opens and closes the flow path, there is a valve body that is in a contracted state and held in the open position in one temperature range with a predetermined transition temperature as the boundary. A temperature-sensing operating valve characterized in that it is equipped with a two-way shape-memory alloy coil spring that is subjected to shape-memory treatment so as to hold the valve body in a closed position when it is in an expanded state in the other temperature range.
