Claims

[Scope of utility model registration request]

(1) An internal pressure regulating cap that has a pressure valve equipped with a pressure spring and a negative pressure valve equipped with a negative pressure spring, and has a spring force stronger than that of a normal spring and the spring force that occurs above a predetermined temperature. 1. A radiator comprising: a shape memory spring having a spring force; and a temperature-sensitive valve device having a piston valve installed therein, in an upper tank of a radiator main body.

(2) A temperature-sensitive valve device is a valve container with a discharge pipe provided at the top and a flow hole formed on the side, and a piston valve having a d-dead between the bead and the upper wall surface of the valve container. A practical use in which a shape memory spring is interposed between the bead and the lower wall surface of the valve container, and the spring action is generated between the bead and the lower wall surface of the valve container, and the spring force is stronger than that of the normal spring.
