PROBLEM TO BE SOLVED: To obtain a fluid control device having a spool valve in which, for example, a spool can smoothly move.SOLUTION: A fluid control device comprises: a spool valve having an introduction port which can introduce fluid into a supply pressure chamber, a discharge port which can discharge the fluid from the supply pressure chamber, and a supply port which supply the fluid to a control object from the supply pressure chamber; a control valve for controlling the pressure of a control pressure chamber by changing an opening/closing state; a control part for controlling the opening/closing state of the control valve on the basis of a command value; and a storage part which stores past data related to at least one of a control value of the control valve by the control part, a calculation value by the control part and a detection value by a sensor. The control part differentiates the opening/closing state of the control valve based on the command value on the basis of the past data.SELECTED DRAWING: Figure 6

    【課題】例えば、スプールがより円滑に移動することが可能なスプール弁を有した流体制御弁装置を得る。【解決手段】流体制御弁装置は、供給圧室に流体を導入可能な導入ポートと、供給圧室から流体を排出可能な排出ポートと、供給圧室から流体を制御対象に供給する供給ポートと、が設けられた、スプール弁と、開閉状態を変化させることにより制御圧室の圧力を制御する制御弁と、指令値に基づいて制御弁の開閉状態を制御する制御部と、制御部による制御弁の制御値、制御部による算出値、およびセンサによる検出値のうち少なくとも一つに関する過去データを記憶する記憶部と、を備え、制御部は、過去データに基づいて、指令値に基づく制御弁の開閉状態を異ならせる。【選択図】図6
