Influence of the feedback spring parameters on the servovalve flow characteristics

One of the most frequently used electrohydraulic transducers is servovalve with mechanical feedback linkage realized by means of a feedback spring. In case of pressure-flow control applications of such servovalve one of the crucial problems is to match its feedback spring rigidity to flow output characteristics. This paper contains a linear mathematical model which enables to obtain suitable relation between the input of current of torque motor and flow output of the valve in steady states.
