PURPOSE: A pilot servo valve system is provided to supply rapid response of a spool by controlling a displacement of the spool through chancing electrode and ER fluid. CONSTITUTION: System of a pilot servo valve comprises a base plate(12) mounted in a housing(10); a spool(14) movably installed on an upper portion of the base plate; a rod(36) guiding movement of the spool by being mounted on both ends of the spool; a leaf spring(16) combined to a middle portion of the spool; a hinge supporting an upper portion of the leaf spring; plural electrodes(32) arranged on a pilot(26) of the housing; an amplifier(22) connected to the electrode; and a controller(24) engaged with the amplifier. Thereby, the system of the pilot servo valve supplies rapid response of the spool by controlling a displacement of the spool through chancing the electrode and ER fluid.
