Patent ID: 8915260

Claim:
A pressure relief device for a system containing a pressurized fluid, comprising; a main valve body including an axial passageway defining an inlet port, an outlet port, and a fluid flowpath between the inlet and outlet ports; a valve plug positioned to seal the inlet port of the main valve body; a force transmission component connected to the valve plug, the force transmission component comprising a curved protrusion member; an activation component installed between the protrusion member and a mounting surface, the activation component configured to prevent axial movement of the valve until a predetermined pressure is exerted on the valve; and a piston slidably housed within the relief device between the protrusion member and the activation component, the piston having a first end and a second end, wherein the first end and second end are exposed to environmental pressure; wherein the force transmission component only transfers an axial force acting on the valve plug to the activation component through the curved protrusion member and piston.
