を備えてなる油圧制御装置。A housing that forms a load port and a tank flow path, one end facing the seat side of the tank flow path that opens to the load port side, and the other end facing the pressure chamber side, and this pressure chamber is connected to the load port. A main poppet is formed with an orifice that communicates with the pressure chamber, and the tip facing the pressure chamber is brought into pressure contact with the main poppet to close a hole formed in the main poppet. A control iron is formed in the control iron and is configured to block the passage connecting the chamber and the tank flow path, while moving in the direction of opening the passage in response to the action of the control pressure. An oil passage that connects the chamber to the tank, and a pilot that normally closes this oil passage and opens the oil passage to communicate the pressure chamber with the tank when the pressure on the load port side exceeds the set pressure. A hydraulic control device comprising a poppet.
