Abstract: A temperature control regulating valve includes a mounting seat and a valve disc set on the end face of the mounting seat. The mounting seat is provided with a valve hole that penetrates through the mounting seat. The end of the valve disc close to the valve hole is slidably set relative to the valve hole, sliding with temperature changes. The structure of the temperature control regulating valve is simple. With temperature changes, the valve disc deforms, gradually changing its relative position to the valve hole, gradually blocking the valve hole or gradually overlapping the valve disc hole with the valve hole, allowing for a gradual change in the cross-sectional area through which fluid can pass, automatically adjusting the flow rate of the fluid with temperature changes.

Abstract: An aircraft exterior light unit may comprise a magnetically controlled fluid drain valve configured to expel liquid water from the light unit. The valve may include a permanent magnet configured to induce a magnetic flux circuit that generates a magnetic force configured to close the valve. The valve may be configured to open when the pressure inside the light unit exceeds the magnetic force. As the valve opens and expels the water, the pressure within the light unit may decrease, equalizing with that of the external environment. As the magnetic force generated by the magnet increases as the valve is open and the water expelled, the magnet may be configured to close the valve once more. As such, the magnet may be configured to control a self-acting fluid drain valve in an aircraft exterior light.
