Summary:To provide a hydraulic drive system which can automatically remove air in fluid while being automatically operable at any posture and position of a cylinder actuator.SOLUTION: A hydraulic drive system includes: a three-port cylinder actuator 1 having a piston 15; at least two operation valves including a first operation valve 31 and a second operation valve 32; an exhaust valve 33; a tank 8 for storing fluid; a motor pump 7 for supplying the fluid to the operation valves from the tank; and a control device 100 for controlling all of the operation valves and the exhaust valve and the motor pump. The first operation valve is connected to a bottom port 11 of the three-port cylinder actuator. The second operation valve is connected to a rod port 12 of the three-port cylinder actuator. The exhaust valve 33 is connected to the exhaust port 13 of the three-port cylinder actuator.SELECTED DRAWING: Figure 1 【課題】任意のシリンダアクチュエータの姿勢や位置においても自動操作が可能でありながら、流体中の空気を自動的に除去することができる液圧駆動システムを提供する。【解決手段】ピストン15を有する3ポートシリンダアクチュエータ1と、第1の作動弁31と第2の作動弁32とを含む少なくとも2つの作動弁と、排気弁33と、流体を貯留するタンク8と、前記タンクから前記作動弁に前記流体を供給するモータポンプ7と、前記作動弁および前記排気弁の全ての弁と前記モータポンプを制御する制御装置100と、を含む液圧駆動システムであって、前記第1の作動弁は、前記3ポートシリンダアクチュエータの底部ポート11に接続され、前記第2の作動弁は、前記3ポートシリンダアクチュエータのロッドポート12に接続され、前記排気弁33は、前記3ポートシリンダアクチュエータの排気ポート13に接続される。【選択図】図1
