ABSTRACT:
In a pressure-reducing regulator valve for high-pressure gases, the diaphragm is linked to the movable valve member controlling the flow of gas between the high-pressure inlet and the regulated outlet. The linkage is done through a lost-motion connection so that the diaphragm can be set to deflect by a nominal amount from its relaxed position at the time that it starts to open the valve seat assembly and can be slightly deflected from its relaxed position to pull the valve against the seat of the valve seat assembly. Sealing prevents leakage through the diaphragm assembly.
