Patent ID: 7506662

Claim:
An improved one-way fluid valve construction, comprising: a valve housing including at least one valve port and at least one control port, each said valve port and said control port defining a hollow passage extending from an inlet face of said valve housing to an outlet face of said valve housing; a control member disposed within said control port, said control member having first and second faces, a first face in fluid communication with said inlet face and a second face in fluid communication with said outlet face, said control member movable within said control port between a first position and a second position; a resilient member which biases said control member toward said first position, said control member transitioning from said first position to a second position upon the occurrence of a predetermined fluid pressure differential as between said inlet face and said outlet face; a control rod rotatably journaled within said housing and extending between said control member and a portion of said valve port, said control rod having a coupling at a first portion adjacent to said control member, said coupling engaging a portion of said control member and rotating said control rod a predetermined angular amount when said control member transitions between said first position and said second position; a sealing face formed on a second portion of said control rod, said sealing face forming a seal with an orifice defined in said hollow passage when said control rod is rotated by said control member to a control rod sealed position, said sealing face unsealing from said orifice when said control rod is rotated by said control member to a control rod unsealed position.
