| Abstract: | The characteristics and structure of electro-hydraulic servovalve with compensative restrictors are analyzed.A pair of compensative restrictors is added in the cavity on both ends of main spool of two stage servovalve to adjust its dynamic characteristics.The transfer function model of this valve is got,and the influence of these compensative restrictors to electro-hydraulic servovalve is analyzed. |
