Lubrication system with passive valve
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.
1. A system, comprising:
a mechanical assembly;
a pumping mechanism configured to deliver a lubricating media to a mechanical assembly; and
a cooling system comprising:
a storage unit configured to contain a supplemental media; and
a valve operable to deliver the supplemental media from the storage unit to the mechanical assembly when a first force is greater than a second force, wherein the first force is substantially caused by the pressure of the supplemental media, the valve comprising:
a biasing member that changes volume as temperature changes and exerts a substantial portion of the second force, wherein the second force decreases as the temperature of the biasing member increases.
2. The system according to claim 1 , wherein the biasing member is a spring.
3. The system according to claim 1 , wherein the supplemental media is a lubricant.
4. The system according to claim 1 , wherein the mechanical assembly comprises a plurality of gears.
5. The system according to claim 1 , wherein the valve comprises an inner chamber and an outer chamber.
6. The system according to claim 5 , wherein the inner chamber comprises the biasing member, the outer chamber comprises a port that allows the supplemental media to flow from the storage unit to the mechanical assembly when the valve is open.
7. A valve comprising:
a piston configured to open the valve when a first force is greater than a second force;
supplemental media, wherein the pressure of the supplemental media exerts a substantial portion of the first force;
a biasing member that changes volume as temperature changes and exerts a substantial portion of the second force, wherein the second force decreases as the temperature of the biasing member increases.
8. The valve according to claim 7 , wherein the biasing member is a spring.
9. The valve according to claim 7 , wherein the supplemental media is a lubricant.
10. The valve according to claim 7 , wherein the valve comprises an inner chamber and an outer chamber.
11. The valve according to claim 10 , wherein the inner chamber comprises the biasing member, the outer chamber comprises a port that allows the supplemental media to flow from a storage unit to a mechanical assembly when the valve is open.
