Original Kurzfassung:
A detailed mathematical model for a hydraulic servo-valve with a flapper-nozzle pilot-stage is of sixth order. This model requires numerous data which to a great part must be taken from extensive experiments. By singular perturbation arguments the order can be reduced at least to three in many cases even more to one. The coefficients of this reduced models can be determined fom the step response- and frequency-response curves, which are provided as normal data in the manufacturer's valve-catalogues.
