Abstract
PURPOSE: To arrange a valve of a cooling system to be controlled for operation freely and manually without being influenced by any operating condition of the system by applying a shape memory alloy to the valve driving element for an expansion valve.
CONSTITUTION: Valve driving element 21 is made of a shape memory alloy. In general, a shape memory alloy is on the martensite abnormal phase when it is under a certain fixed temperature and is liable to be displaced by the force applied from outside. Therefore, the valve driving element 21 is deformed to make a convex curve in the centre by the elestic force of the spring 26 and thus the valve 25 is on the condition to keep the orifice 14 open. then, if you charge on the heater 24 to heat up the valve driving element 21 beyond the prescribed temperature, the martensite abnormal phase vanishes to return to the original metal phase bringing the valve driving element 9 to the original flat shape. With this flat element, the valve 25 changes position resisting against the elastic force of the spring 26 to the direction to close the orifice 14 completely.
