摘　　要：The magnetic fluid is used as working medium in pilot stage of electro-hydraulic servoamplifier. Utilizing the magnetization viscous character of the fluid, a new type of electro-hydraulicservo amplifier without any moving parts in its pilot stage has been developed. This research provides a way for improving the frequency property and reliability of electro-hydraulic servoelements.The magnetic fluid is used as working medium in pilot stage of electro-hydraulic servoamplifier.
