Abstract: PURPOSE: A valve is opened by generating a force disproportional to the valve stroke by using a permanent magnet and a magnetic body. CONSTITUTION: In a valve to open/close a valve disk(9) operating a central link(10) by a spring(5) and a link(4), a magnetic body(2) is installed in upper part of the central link. A permanent magnet(1) is installed in upper part of the magnetic body, and is positioned at a link frame(3). When an inner pressure of the aircraft reaches a certain value, the valve is opened to its utmost stroke. When the pressure is reduced, the valve is closed.
