サーボ弁。[Scope of Claim for Utility Model Registration] By applying an input signal to a torque motor, a current is passed through the coil, the flapper is operated by the attraction force generated by the magnetic action, and the outflow flow rate from the nozzle is changed to change the position of the spool of the valve body. An electric feedback servo valve characterized in that a displacement sensor is provided to detect the position of the spool, and a displacement signal from the displacement sensor is fed back to the input signal to control the position of the flapper. .
