Abstract:
A valve, comprising:a housing having, a valve chamber bounded by a valve chamber wall, a valve chamber opening edge bounding a first valve chamber opening, a valve chamber wall protrusion, and a second valve chamber opening bounded by a fluid flow opening edge in the valve chamber wall; a chamber shuttle having, a chamber shuttle cavity bounded by a chamber shuttle cavity wall, a first chamber shuttle opening edge bounding a first chamber shuttle cavity opening, and a second chamber shuttle opening edge bounding a second chamber shuttle cavity opening, the chamber shuttle adapted for travel within the valve chamber in a direction that will enabled contact with the valve chamber wall protrusion; a shuttle-plug, positioned within the chamber shuttle cavity and having a shuttle-plug edge that is biased with a force from against the chamber shuttle cavity wall to resist the first chamber shuttle opening edge thereby closing the first chamber shuttle cavity opening, the chamber shuttle movable against the force to disengage the first chamber shuttle opening edge from the shuttle-plug edge thereby opening the first chamber shuttle cavity opening, the shuttle-plug edge resisted instead by the valve chamber wall protrusion.
