PROBLEM TO BE SOLVED: To suppress a flow sound while securing a sufficient flow speed of a working fluid, in the flushing of a fluid pressure operator into which the working fluid from a high-pressure source is introduced while being adjusted in pressure by an electromagnetic linear valve, and in which an output corresponding to the pressure of the introduced working fluid is obtained.SOLUTION: The servo pressure P(output) of a regulator being a fluid pressure operator is monitored as a working index, and the flushing of the regulator by the working fluid which is introduced from a high-pressure source via an electromagnetic linear valve is performed while feedback-controlling a supply current Ito the electromagnetic linear valve so that the servo pressure reaches set pressure P. By the feedback control, a sufficient flow speed of the working fluid at the flushing can be secured, and a flow sound is suppressed by suppressing the flow speed of to become excessive.SELECTED DRAWING: Figure 5

    【課題】 高圧源からの作動液が電磁式リニア弁によって圧力調整されて導入され、その導入された作動液の圧力に応じた出力が実現される液圧作動器のフラッシングにおいて、充分な作動液の流速を確保しつつ、流動音を抑制する。【解決手段】 液圧作動器であるレギュレータのサーボ圧PSRV(出力)を作動指標としてモニタし、そのサーボ圧が設定圧PSRV-Sとなるように、電磁式リニア弁への供給電流IAのフィードバック制御を行いつつ、その電磁式リニア弁を介して高圧源から導入される作動液によるレギュレータのフラッシングを行う。フィードバック制御により、フラッシングにおける充分な作動液の流速が確保されるとともに、その作動液の流速が過度となることが抑制されることで、流動音が抑制される。【選択図】 図5
