As shown in FIG. 1, the automatic on-off valve according to the present invention has a metal or resin holding sleeve 3 provided with a metal or resin orifice disc 2 at an arbitrary axial position inside a metal or resin guide pipe 1. The valve rod 4 is penetrated through the opening 13 of the orifice disc 2 and the valve seat rubber 5 is fixed to the step portion at the inner end of the valve disc 4 on the valve seat rubber 5 side. The normal coil spring 6 for bias is arranged, and the stopper ring 8 is fixed by a screw or an adhesive material so as to receive the reaction force of the coil spring 6, while the valve seat rubber 5 on the opposite side is not attached. A coil spring 7 made of a shape memory alloy is arranged in the above, and a stopper ring 9 is fixedly attached to the valve rod 4 with a screw or an adhesive so as to receive the reaction force of the coil spring 7.

る。When a hot fluid having a temperature equal to or higher than a certain temperature flows in from the inflow port 10 of the guide pipe 1, the shape memory effect of the coil spring 7 causes the spring force of the normal coil spring 6 for bias and the reaction force against fluid pressure and valve rod movement. The shape memory alloy coil spring 7 comes into contact with the thermal fluid to exert a shape memory effect and expands, and transmits the reaction force to the stopper ring 8 to cause the valve seat rubber 5 to make an orifice. The valve rod 4 can be moved to the right until it comes into close contact with the disc 2 to close the flow of the thermal fluid. In addition, when a cold fluid having a temperature below a certain temperature is flown into the inlet 10 from this state, or when the shape memory alloy coil spring reaches a temperature below a certain temperature due to natural cooling or the like, the spring force due to the shape memory effect is generated. Because of the decrease, the spring force of the bias coil spring 6 overcomes to move the valve rod 4 to the left to form a sufficient gap between the valve seat rubber 5 and the orifice plate 2, and the outlet 10 'as shown by the arrow. It is possible to open the flow path of the fluid leading to.
