速度を制御するよう設けて成る液体制御弁。 The liquid inflow passage and outflow passage are provided in the main body so as to communicate with each other through a communication hole formed with a valve seat, and the valve seat is fitted into the guide hole of the main body so as to be able to move freely in the axial direction so as to be able to move away from and sit on the valve seat. A valve element is inserted to open and close the communication hole, and pressure on the inflow passage side is applied to the valve element in the opening direction, and an action chamber pressure and a spring are formed on the back of the valve element, which communicates with the inflow passage side via a throttle passage. A force is applied to the valve body in the closing direction, an action chamber is provided so that communication can be cut off to the low pressure side by moving the pilot valve body, and the tip is inserted into the end of the valve body opposite to the action chamber. A brake member is disposed in the main body, and the liquid in the action chamber formed by fitting the brake member into the valve body is throttled and controlled to flow out and control the speed at which the valve body moves from the open position to the closed direction. Liquid control valve consisting of
