Abstract:
A valve assembly comprising:a housing having an interior cavity and at least one conduit which forms at least one fluid flow path; a member slidably disposed within said interior cavity and having at least one tapered channel which cooperates with said at least one conduit to form said at least one fluid flow path, said member being selectively movable from a first position in which said at least one tapered channel causes said at least one fluid flow path to have a first volume, to a second position in which said at least one tapered channel causes said at least one fluid flow path to have a second volume; and a selectively expandable diaphragm which is disposed at a first end of said cavity and which abuttingly engages a first surface of said member, said selectively expandable diaphragm being effective to selectively expand upon receipt of an amount of pressurized fluid, effective to cause said member to move from said first position to said second position.
