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 venturi valve region therein. The venturi valve region includes a fluid jacket that encases at least a portion of the venturi valve region. 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 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.
