Beschreibung
Zusammenfassung:	The invention discloses a direct-acting servo valve, which belongs to the field of hydraulic elements, is mainly applied to a servo hydraulic system and mainly comprises a valve body, a valve core, a valve sleeve, a voice coil motor, a controller, a connecting mechanism, a control plug mechanism and a centering mechanism, and the valve sleeve can be switched between a left position and a right position; the control plug mechanism can be switched between a plugging state and an opening state; the connecting mechanism is fixedly connected between the valve body and the voice coil motor; the centering mechanism can be switched between a locking state and a loosening state; when the control plug mechanism is in a plugging state, the valve sleeve is in a right position, the centering mechanism is in a locking state, and at the moment, the centering mechanism is fixedly connected with the valve element; when the control plug mechanism is in an open state, the valve sleeve is in a left position, the centering mechan
