口へ導くようにしたアンロード弁。A body having a primary side port, a secondary side port, and a passage that communicates these ports, a valve body that is unseated from the opposite side of the passage with respect to a valve seat formed facing the passage, and this valve body. pressure regulating means for adjusting the elastic force that presses the valve against the valve seat, and a piston valve provided on a portion of the valve stem extending from the valve body to the secondary port side, and the piston valve has a piston reverse A stop valve is provided, and when pressure liquid flows from the outlet port, this liquid passes through the internal port of the piston and pushes the check valve open to reach the outlet port, so that the outlet pressure is increased. When the value exceeds the value set by the pressure regulating means, the check valve closes and the piston slides to separate the valve body from the valve seat, allowing the pressure liquid on the next side to flow through the valve body and into the spill outlet. An unload valve designed to lead to.
