Abstract: A valve with supplemental media and a piston configured to open the valve when a first force is greater than a second force. The pressure of the supplemental media exerts a substantial portion of the first force. The valve also has a biasing member that changes volume as temperature changes and exerts a substantial portion of the second force. The second force decreases as the temperature of the biasing member increases.

Abstract: A lubrication system is disclosed. The lubrication system may have a collection area for collecting lubricating media and a pumping system for transporting the lubricating media from a withdrawal location of the collection area to a distribution location of the collection area. The lubricating media may collect in the collection area to a static level when the pumping system is off and to a dynamic level when the pumping system is on. The lubrication system may also include a drain valve located between the static level and the dynamic level. The drain valve may operable to open to drain a portion of the lubricating media in response to the lubricating media reaching a predefined threshold temperature and level. The valve may comprise a thermally-activated material, and the material may substantially change phase or volume upon reaching a predetermined temperature.
