にしたことを特徴とする電磁油圧アクチュエータ。The I-pressure actuator is equipped with a three-way switching valve driven by a solenoid, and drives the piston of the actuator by hydraulic pressure supplied through the three-way switching valve. In the fixed core of the solenoid component, a movable piece of magnetic material is installed inside the solenoid component so that the movable piece can be slightly slidable therein, and there is a three-sided valve body that is driven by the movable piece and a fixed part that forms an oil path for each port. An electrohydraulic actuator characterized in that a switching valve component and a piston of the actuator are housed and provided, and the output hydraulic pressure of the three-way switching valve component is applied directly to the piston.
