An improved one-way fluid valve construction is provided. A valve housing (102) includes one or more valve ports (108) and control ports (110). A control member (304) is disposed within the control port (110). The control member (304) is movable within the control port (110) between a first position and a second position. A control rod (302) can extend between the control member (304) and a portion of the valve port (108). A control rod coupling (402) interacts with the control member (304) to cause a rotational or pivotal movement the control rod (302) through a predetermined angular arc in response to movement of the control member (304). A sealing face (404) formed on a second portion of the control rod (302) advantageously forms a seal with an orifice (316) that separates an input side of the valve port (108) from an output side. The seal can be formed when the control rod (302) is in a control rod sealed position. When the control rod (302) is rotated to a control rod unsealed position, the sealing face unseals from the orifice (316).

We claim: 1. 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. 2. The improved valve of claim 1, wherein said at least one valve port is twelve valve ports. 3. The improved valve of claim 1, wherein said at least one control port is three control ports. 4. The improved valve of claim 1, wherein said resilient member is a spring. 5. The improved valve of claim 1, wherein said coupling includes a plurality of gear teeth. 6. The improved valve of claim 1, wherein said control member includes a plurality of gear teeth formed on a shaft of said control member. 7. The improved valve of claim 1, wherein said control rod is formed from at least one section. 8. The improved valve of claim 1, wherein said control rod includes two or more guide channels for maintaining said control rod in proper alignment with said valve housing. 9. The improved valve of claim 1, wherein said control rod includes a plurality of ribs disposed on a portion of said control rod opposed from said sealing face. 10. The improved valve of claim 1, wherein said control rod includes at least one land opposed from said sealing face and at least one bridge extending from said sealing face to said land. 11. A valve and fluid compressor arrangement, comprising: a fluid compressor; a valve housing having an inlet face and an outlet face; at least one valve port disposed in the valve housing defining a flow channel between said inlet face and said outlet face; at least one control port disposed in the valve housing defining a cavity between said inlet face and said outlet face; 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. 12.
