Claims (1)
工業用ロボツトにおいて、前記アクチユエータを
正方向および逆方向にそれぞれ駆動すべく圧油を
供給する流路にバイパス流路を設け、該バイパス
流路の途中には、ポペツトを弁座に当接させるこ
とによりバイパス流路を開閉する弁が設けられた
ことを特徴とする工業用ロボツト。 In an industrial robot whose arm is driven by a hydraulic actuator, a bypass flow path is provided in the flow path for supplying pressure oil to drive the actuator in the forward direction and the reverse direction, and a poppet is provided in the middle of the bypass flow path. An industrial robot characterized by being provided with a valve that opens and closes a bypass flow path by bringing the valve into contact with a valve seat.
