PRESSURE ADJUSTING VALVE AND CONSTRUCTION MACHINE
To provide a pressure adjusting valve capable of simplifying a structure.SOLUTION: A pressure adjusting valve 10 includes a drive spool 30 capable of moving in an axial direction, electromagnetic proportional valves 40A and 40B that have a control spool 41 disposed so as to move in an orthogonal axial direction, and are disposed on both sides in the axial direction of the drive spool 30, and position compensation mechanisms 50A and 50B that compensate an actual position of the drive spool 30 with respect to a command position of the drive spool 30 based on the electromagnetic proportional valves 40A and 40B, on the basis of displacement converting a position of the drive spool 30 in the axial direction into the orthogonal axial direction.SELECTED DRAWING: Figure 2
【課題】構成を簡素化することができる圧力調整弁を提供する。【解決手段】実施形態の圧力調整弁１０は、軸方向へ移動可能な駆動スプール３０と、直交軸方向に移動可能に配置された制御スプール４１を有し、駆動スプール３０の軸方向の両側に配置された電磁比例弁４０Ａ，４０Ｂと、軸方向の駆動スプール３０の位置を直交軸方向に変換した変位に基づき、電磁比例弁４０Ａ，４０Ｂに基づく駆動スプール３０の指令位置に対する実際の駆動スプール３０の位置を補償する位置補償機構５０Ａ，５０Ｂと、を備える。【選択図】図２
