ABSTRACT:
An in-line high pressure fluid release valve is formed by a valve body having a cylinder and having a transverse opening forming a fluid passageway interposed in a fluid conductor. A piston normally closing the fluid passageway and having a fluid passageway size transverse opening is guided to prevent angular rotation during longitudinal sliding movement in the cylinder by a piston rod and a cylinder wall supported guide rod projecting into a piston wall slot for mating and mismating the piston opening with the flow passageway. A pin cage connected with the piston rod end of the cylinder axially supports a collapsible pin normally biasing the piston to a fluid passageway closed position until upstream fluid pressure of a predetermined value channeled through a cylinder wall fluid bypass at the piston end opposite the piston rod to bias the piston toward a passageway open position for releasing fluid pressure downstream. A fluid bypass check valve holds fluid under pressure in the piston cavity and against the piston end opposite its rod to insure full travel of the piston for axially aligning its opening with the fluid passageway.
