Abstract

A pressure relief valve with a trigger mechanism having a plurality of tines on the ejector which engage with a fixed stop. The tine ends and/or the fixed stop are chamfered. The valve opens when the force from the contained fluid exceeds the force of the spring plus the force necessary to move the tines out of alignment with the fixed stop. The trigger pressure of the valve can be adjusted by adjusting the geometry of the tines. This is accomplished by using interchangeable tine sections on the ejector. Pressure is contained by a primary seal located on the outer diameter of the ejector.
