ABSTRACT:
An axially bored valve body having inlet and exhaust ports is provided with a valve movable toward and away from a sealed position in the inlet port at its pressure connected end. A cap closes the end of the body opposite its inlet port. An axially collapsible member is axially interposed between the downstream end of the valve stem and the cap to normally maintain the fluid passageway between the ports closed. Excessive fluid pressure against the valve at the inlet port collapses the collapsible member and unseats the valve to open the fluid passageway.
