ROTARY VALVE AND FLUID PRESSURE ACTUATOR UNIT INCLUDING THE SAME
PROBLEM TO BE SOLVED: To improve controllability of a fluid pressure actuator rotating a drive object around a rotational shaft.SOLUTION: A rotary valve controlling a flow rate of hydraulic oil supplied/discharged to/from a hydraulic cylinder rotating a wing around a rotational shaft includes a rotor 60 rotating with rotation of the wing with the rotational shaft as a center, and a first control flow passage 61 and a second control flow passage 65 formed in the rotor 60 and controlling the flow rate of hydraulic oil supplied/discharged to/from the hydraulic cylinder. The first control flow passage 61 and the second control flow passage 65 each change resistance imparted to flow of passing hydraulic oil with rotation of the rotor 60.SELECTED DRAWING: Figure 3
【課題】回転軸を中心に駆動対象を回転させる流体圧アクチュエータの制御性を向上させる。【解決手段】回転軸を中心にウィングを回転させる油圧シリンダに給排される作動油の流量を制御するロータリーバルブであって、回転軸を中心とするウィングの回転に伴い回転するロータ６０と、ロータ６０に形成され油圧シリンダに給排される作動油の流量を制御する第一制御流路６１及び第二制御流路６５と、を備え、第一制御流路６１及び第二制御流路６５は、ロータ６０の回転に伴い、通過する作動油の流れに付与する抵抗がそれぞれ変化する。【選択図】図３
