Claims (1)
接続し他方の受圧面の大きな圧力室はパストン行程端位
置検出手段からの位置信号で切換ってタスクと圧力源に
交互に接続する３ポート方向切換弁に接続してピストン
を往復動させるシリンダ制御装置において、受圧面の小
さな圧力室を圧力源に接続する流路に流量制御弁と圧力
源側へのみ流体流れを許すチェック弁を並設したことを
特徴とするシリンダ制御装置。The small pressure chamber on the pressure-receiving surface of the differential cylinder is always connected to the pressure source, and the large pressure chamber on the other pressure-receiving surface is switched by a position signal from the paston stroke end position detection means and alternately connected to the task and pressure source. In a cylinder control device that connects to a 3-port directional control valve to reciprocate a piston, a flow control valve and a check valve that allow fluid to flow only toward the pressure source side are installed in the flow path that connects the small pressure chamber on the pressure receiving surface to the pressure source. A cylinder control device characterized by being installed in parallel.
