記載のアンロード弁。[Claims for Utility Model Registration] A body having a passage communicating between a primary port and a secondary port, a spillway communicating with the passage below, and a valve formed facing the lower side of the passage. A valve body is seated from the opposite side of the passage with respect to the seat, and the valve body is formed integrally with the valve body and is formed on the upper end side of the valve rod extending upward from the body to press the valve body against the valve seat. and a piston valve provided at a portion of the valve stem in the passage, the piston valve being equipped with a piston and a check valve,
- When the pressure liquid flows from the downstream port, this liquid passes through the internal port of the piston, pushes the check valve open, and reaches the secondary side, and the secondary side pressure is set by the pressure regulating means. When the specified value is exceeded, the check valve closes, the piston slides, and the valve body is separated from the valve seat, so that the downstream pressure liquid is guided to the spill port through the valve body. An unload valve featuring: 2. The unload valve according to claim 1, wherein the elastic force is a compression coil spring interposed between the body and the pressure regulating means.
