Abstract

PURPOSE: To obtain sure control for a valve by a small electric power in an electric switch valve used in a refrigerating cycle of refrigerant by adopting a form-memorizing alloy for a drive element of the valve for obtaining a small-sized switch valve.
CONSTITUTION: A heater 10 is wound round a plate-shaped valve drive element 9 made of Ni-Ti alloy, and an operation rod 14 is inserted between the element 9 and a diaphragm 11. Generally, in a maltensite transformation phase, a form- memorizing alloy is easily displaced by an external force. This valve drive element 9 is transformed by the elasticity of a spring 13 to be convexed in the center and a valve body 12 is separated from an opening part 5 for conducting fluid from the first passage 2 to the second passage 3. Meanwhile, when the heater 10 is electrified to heat this alloy over a fixed temperature, the maltenside transformation phase is extinguished to obtain the original metal phase of a high elesticity, and the valve drive element 9 is returned into a flat state before transformation. As it is made flat, it pushes the valve body 12 downward against the spring 13, and closes the opening part 5 for intercepting the flow of the fluid.
