PRESSURE ADJUSTING VALVE AND CONSTRUCTION MACHINE
To provide a pressure adjusting valve capable of suppressing enlargement in a direction orthogonal to an axis of a spool.SOLUTION: A pressure adjusting valve 10 includes a drive spool 30 capable of moving in an axial direction, an electromagnetic proportional valve 40A that has a control spool 41 arranged in the same direction as the drive spool 30, and a position compensation mechanism 50A that is disposed between the drive spool 30 and the control spool 41 in the axial direction, and compensates an actual position of the drive spool 30 with respect to a command position of the drive spool 30 based on the electromagnetic proportional valve 40A.SELECTED DRAWING: Figure 3
【課題】スプールの軸線と直交する方向への大型化を抑制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、駆動スプール３０と同方向に配置された制御スプール４１を有する電磁比例弁４０Ａと、駆動スプール３０と制御スプール４１との軸方向の間に配置され電磁比例弁４０Ａ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と、を備える。【選択図】図３
