Abstract
A control motor for a servo valve is provided. The control motor comprises a control element which can carry out a pivotal movement due to an electric input signal supplied to said motor. The movement of the control element causes a corresponding change of hydraulic resistances and, as a consequence, changes in hydraulic output signals of an hydraulic amplifier actuated by said motor.
