Abstract
A fluid circuit includes a device, a cooler, and a valve. The valve includes a housing, a sealing member, a biasing device, and an actuator. The sealing member moves inside the housing between a first position and a second position. The actuator includes a smart material that is activated when the temperature of a fluid inside the housing exhibiting at least a first temperature, causing the sealing member to move to the second position. The smart material is deactivated when the fluid is a sufficient number of degrees less than the first temperature, causing the sealing member to move to the first position. The fluid flows from the housing to the device and then to the housing when the sealing member is in the first position. The fluid flows from the housing to the cooler and then to the device when the sealing member is in the second position.
