Abstract:
A thermoresponsive valve (100) comprises an expansion medium (3), a first diaphragm (41), a second diaphragm (42), a contact portion (5), a valve body (6), and a valve seat (7). Formed in the second diaphragm (42) and the valve body (6) is a through-hole (61) that passes through the second diaphragm (42) and the valve body (6) and that communicates with a valve hole (71) when the valve body (6) is closed.

Formed in the contact portion (5) is a communication channel (53) that allows communication between the through-hole (61) and a space (43) between the first diaphragm (41) and the second diaphragm (42) in a state in which the contact portion (5) is in contact with the first diaphragm (41).
