御弁。 a valve body having a high pressure port and a low pressure port;
It is slidably provided inside the valve body, and can be opened by moving between the high pressure port and the low pressure port in one direction (hereinafter referred to as the opening direction), and in the other direction (hereinafter referred to as the closing direction). ), and a pressing means for pressing the valve body in the closing direction, and an internal volume inside the valve body is configured to move the valve body in the opening direction. A damper chamber is formed which increases as the valve body moves in the closing direction and decreases as the valve body moves in the closing direction.When the pressure on the high pressure port side exceeds the valve opening pressure set by the pressing means, the high pressure port A pressure control valve configured such that the valve body is moved in the opening direction by the pressure of hydraulic oil on the side, characterized in that the damper chamber is communicated with a low pressure side via a throttle part. control valve.
