ABSTRACT:
An excess pressure relieving means is illustrated for use with fluid pressure reducing apparatus wherein fluid passes from a high pressure inlet chamber to a reduced pressure outlet chamber and includes a valve member having a relief port carried by a diaphragm which extends across the outlet chamber, a closure member carried by the diaphragm normally closing the fluid relief port, and an operator carried by the closure member engaging a stop which limits movement of the closure member but which permits further movement of the valve member producing a separation of the valve and closure members permitting excess fluid pressure to be dissipated through the relief port.
