動発生機。[Claims for Utility Model Registration] An electrodynamic vibration generator, a servo valve having a hydraulic power source and a hydraulic valve driven by the electrodynamic vibration generator, and a servo valve that draws oil from the hydraulic power source by driving the hydraulic valve. The concentric two-cylinder actuator has an outer cylinder and an inner cylinder part extending concentrically, and has a contraction side pressure and an expansion side pressure in the outer cylinder part and the inner cylinder part, respectively. A cylinder having a hollow inner hole and a piston sliding on the outer cylinder portion at one end, and a plunger for closing the inner hole fixed at the other end, the hollow inner hole sliding on the inner cylinder portion. The piston rod is configured to have an equal pressure receiving area with the piston receiving pressure on the contraction side and the plunger receiving pressure on the expansion side, and a non-contact type detection device for detecting displacement, velocity, and acceleration of the piston rod is provided in the hollow portion of the piston rod. An electro-hydraulic vibration generator characterized by:
