Two way non leaking flow valve with full-open capability |
摘要 |
Disclosed is a two way valve that has a valve chamber having a first valve chamber opening bounded and a fluid flow opening. A chamber shuttle, adapted to travel within the valve chamber, is characterized by a chamber shuttle cavity and has a first chamber shuttle cavity opening and a second chamber shuttle cavity opening. A shuttle-plug that is biased by a force established within the valve closes the chamber shuttle cavity to establish a closed fluid-flow state. The chamber shuttle is also movable against the biasing force thereby resisting the shuttle-plug by a structure fixed relative to the valve chamber and opening the chamber shuttle cavity to establish a second fluid-flow state. A preferred embodiment of the invention is incorporated in a valve construction of components that incorporate aspects of the disclosed invention.
