Abstract
A relief valve having a cylindrical case with one side thereof communicated with a fluid-pressure source, a relief piston accommodated in the cylindrical case and slidable therein, a return spring for pressing the relief piston against the fluid-pressure source, a damper chamber provided on a rear-surface side of the relief piston, said damper chamber communicated with the fluid-pressure source through an orifice of the relief piston and used for displaying a buffer action against an operation of the relief piston, and a relief hole bored through a wall of the cylindrical case, the relief hole communicated with the fluid-pressure source when the relief piston retreats due to an increase in pressure generated by the fluid-pressure source.
