Abstract
System, method, and apparatus for controlling circulation of fluid to, and evacuation of the fluid from, an external fluid circuit for heat transfer. A single control valve selectively stops the circulation of fluid from a supply passageway to an external fluid circuit, and diverts fluid to a bypass passageway which creates a suction force at a fluid restriction therein. A suction passageway couples the suction force of bypass passageway to either return passageway or supply passageway, for evacuating fluid from external fluid circuit. No other valve is disposed or required in the supply passageway or the bypass passageway apart from the single control valve. No more than a single actuator is required to operate the apparatus. No more than a single suction passageway is required to be coupled to either supply passageway and/or return passageway. A return check valve disposed in return passageway prevents backflow of fluid through return passageway.
