Pressure regulating valve and construction machine
The invention provides a pressure regulating valve and a construction machine. The pressure regulating valve is provided with a drive spool that is movable in the axial direction; an electromagnetic proportional valve having a control spool disposed in a direction coaxial with the drive spool; and a position compensation mechanism that is disposed at a position between the drive spool and the control spool in the axial direction and compensates for the actual position of the drive spool with respect to the command position of the drive spool based on the electromagnetic proportional valve.
本发明提供一种压力调整阀和建筑机械。本发明的压力调整阀具备：驱动滑阀芯，其能够在轴向上移动；电磁比例阀，其具有配置到与所述驱动滑阀芯同轴的方向的控制滑阀芯；以及位置补偿机构，其配置于在所述轴向上位于所述驱动滑阀芯与所述控制滑阀芯之间的位置，对相对于基于所述电磁比例阀的所述驱动滑阀芯的指令位置的实际的所述驱动滑阀芯的位置进行补偿。
