Claims

[Scope of utility model registration request]

゛An annular movable holder having a spring holder having an inverted U-shaped cross section on the outer periphery and a spring insertion hole in the center is provided in the valve body so as to be movable up and down, and the outer periphery of the movable holder A shape memory alloy spring is installed between the holding part and the valve seat member forming the valve opening, and the movable holder is moved up and down by the expansion and contraction of the shape memory alloy spring, and a central spring insertion hole of the movable holder is configured. The structure is such that a tight bias spring is inserted into the spring, and the upper part of the tight bias spring is formed into a large diameter part that is larger than the spring insertion hole, and from the large diameter part to the lower side. The portion leading to the end is a gradually smaller diameter portion, and the flanged tip of the valve shaft of the valve is inserted into the minimum diameter lower end of the gradually smaller diameter portion, so that the valve is supported so as to be movable up and down within the main body. Features a temperature-responsive valve.
