Abstract:
A pressure relief valve for maintaining a sealing condition under a first pressure differential condition and for breaking the sealing condition when the pressure differential exceeds a second pressure differential condition comprising:a housing;a spring mounted in said housing;a plate mounted in said housing, said plate maintained in a first position by a force generated by said spring;a resilient cantilevered extension mounted in said housing, said resilient cantilevered extension having a base on one end and a sealing surface on the other end with said resilient cantilevered extension angled inwardly so that a greater pressure on an inward side of said cantilevered extension produces a lateral and a radial force on said extension to thereby force said sealing surface into sealing engagement with said plate, said plate displaceable against the force generated by said spring when the pressure differential across said plate exceeds the second pressure differential condition to thereby allow high a pressure fluid to escape from said housing.
