Abstract
According to one embodiment of the invention, a control valve for regulating temperature comprises a conduit, a fluid limiter, a restoring actuator, an opening actuator, and a restoring actuator chamber. The conduit has an inlet, an outlet, and an opening between the inlet and the outlet. The inlet is operable to receive fluid into the conduit and the outlet is operable to dispense of fluid out of the conduit. The fluid limiter is operable to at least partially cover the opening and thereby resist flow of fluid through the opening. The restoring actuator is operable to provide a force that moves the fluid limiter toward the opening to resist flow of fluid through the opening. The opening actuator is operable to provide a second force that moves the fluid limiter away from the opening to allow the flow of fluid through the opening. The opening actuator is activated based on a temperature of fluid in the conduit. The restoring actuator chamber is disposed around the restoring actuator and has a passage in communication with fluid upstream of the opening.
