The present invention is directed to an integral bi-directional flow control valve. The valve includes a housing that defines a passageway for the flow of a fluid in a first direction and a second direction. The housing defines a phase change chamber in the passageway. A first restrictor having a first bore is positioned in the passageway adjacent the phase change chamber. The bore has a volume less than the volume of the chamber. As the fluid flows through the bore in the first direction into the chamber, the fluid changes from a liquid to a gas as it exits the bore. The gas continues to flow through the passageway. A second restrictor having a second bore is positioned in the passageway adjacent the chamber and opposed to the first restrictor. The second restrictor includes a second bore having a volume less than the volume of the chamber. The second bore can be the same size as the first bore or a different size depending on the application. The fluid changes from a liquid to a gas as the fluid flows through the second bore and the chamber in the second direction.

An integral bi-directional flow control valve comprising: a housing defining a passageway for the flow of a fluid in a first direction and a second direction, said housing defining a phase change chamber in said passageway; a fluid flow regulation member having an opening in communication with said passageway and a movable plunger adjacent said opening, said plunger being movable from an open position to a closed position to regulate the flow of fluid through said opening to or from said passageway; a first restrictor having a first bore positioned in said passageway adjacent said chamber, said first bore having a volume less than the volume of said chamber, said first bore regulating said flow of said fluid through said passageway, said fluid changing from a liquid to a gas as said fluid flows through said first bore and said chamber in said first direction; and a second restrictor having a second bore positioned in said passageway adjacent said chamber opposed to said first restrictor, said second bore having a volume less than the volume of said chamber, said second bore regulating said flow of said fluid through said passageway, said fluid changing from a liquid to a gas as said fluid flows through said second bore and said chamber in said second direction.
