<p>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).</p> |
