ABSTRACT:
An improved adjustable pressure relief valve having an adjustable biasing apparatus engaged thereto and exerting a biasing force on a fluid valving device. The valving device has a pressure bearing component that defines a fluid retaining boundary and is acted upon by a fluid under pressure. The fluid pressure exerts a force upon the fluid bearing component counter to the biasing force acting upon the fluid bearing component. The improvement comprises a pressure bearing component retaining device disposed within the pressure relief valve for presenting a barrier to the pressure bearing component, whereby the fluid retaining boundary defined by the pressure bearing component of the valve is maintained in the event of disengagement of the adjustable biasing apparatus from the fluid valving device of the pressure relief valve while the fluid under pressure is acting on the valving device.
