御弁。[Scope of Claim for Utility Model Registration] It is formed into a substantially cylindrical shape, and has a first port communicating with the fluid flow path at one end in the axial direction, and a relief port at the other end in the axial direction, a valve body having a second port opened on a side surface communicating with a fluid flow path; and one end in an axial direction facing the first port, the valve body having a substantially cylindrical shape and being slidably inserted into the valve body. A third port with a smaller diameter than the first port was opened in
A first valve body whose other end in the axial direction is open and communicates with the relief port; and a first valve body which is slidably inserted into the first valve body and which closes the third port when subjected to an elastic force. 2 valve bodies, and an elastic body that applies elastic force to the first valve body and the second valve body, and the first valve body receives the elastic force from the elastic body and moves the first valve body together with the second valve body. When the port is closed and the pressure of the fluid exceeds a first set pressure, the second valve body is configured to move toward the relief port side against elastic force and open the first port, and the second valve body is characterized in that when the pressure of the fluid exceeds a second set pressure that is higher than the first set pressure, it moves to the relief port side against elastic force and opens the third port. pressure control valve.
