Abstract
PURPOSE: To decrease a number of part items in a valve and extremely increase its life, by using a shape-memory alloy for a coil spring in the valve for controlling temperature of cooling water in internal combustion engines.
CONSTITUTION: A coil spring 5 is constituted by a shape memory alloy. At low temperature of cooling water, the coil-shaped shape memory metal 5, being fixed by hooks 8a and 8b on a valve 4, is attracted upward by a coil spring 6 fixed with one end to hooks 10a and 10b of a housing 2 and the other end to hooks 9a and 9b of the valve 4, and the valve 4 is moved upward to close a water line. For an increase of cooling water temperature, the coil-shaped shape memory metal 5 reaches an inverse transformation point to extinguish martensite, return to the set shape and open the water line. This is, a thermostat is all constituted by metals further with no sliding parts, thus to increase reliability further obtain an extremely long life.
