Integral bi-directional flow control valve

An integral bi-directional flow control valve comprising:

• a housing defining a fluid passageway for the flow of a fluid in a first direction and a second direction, said housing defining a phase change chamber in said fluid passageway, said housing including a first restrictor member having an exterior surface, an interior surface, a first end and a second end, said exterior surface including attachment means at said second end, said interior surface defining a first passageway extending from said first end to said second end, said first passageway increasing in size from said first end to said second end, said housing further including a phase change chamber member having an outside surface, an inside surface, a first attachment end and a second attachment end, said inside surface including attachment means at said first attachment end for mating engagement with said attachment means at said second end of said first restrictor member, said outside surface including attachment means at said second attachment end, said inside surface defining a second passageway extending from said first attachment end to said second attachment end, said second passageway being in communication with said first passageway in said first restrictor member;
• a first restrictor having a first bore positioned in said first 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 first 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 fluid 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 fluid 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.

• a first restrictor having a first bore positioned in said first 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 first 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 third 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 third 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.

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.
