録請求の範囲第１項記載の圧力調整弁。[Claims for Utility Model Registration] (1) One end of the pressure regulating compression spring 26 of the pressure regulating valve is brought into contact with the poppet 23, and the other end is brought into contact with one end surface of the piston 33, which is slidable within a specified stroke, and Piston back pressure chamber 3 of the piston 33
By introducing pressure oil from the high pressure chamber 20 into the pressure regulating valve 5, the operating pressure of the pressure regulating valve is gradually increased, and the operating pressure becomes constant at the position where the piston 33 contacts the stopper portion 38a. ,
The pressure oil in the high pressure chamber 20 is transferred to the flow control valve 4 with pressure compensation.
2. A pressure regulating valve characterized in that the pressure regulating valve is introduced into the piston back pressure chamber 35 through the piston back pressure chamber 35. (2) The pressure compensated flow control valve 42 is connected to the piston 33.
2. The pressure regulating valve according to claim 1, wherein the pressure regulating valve is disposed coaxially with the utility model.
