摘　　要：提出了把磁流体添加入射流管伺服阀力矩马达的工作间隙,从而改善射流管伺服阀动态响应的方法,给出了采用磁流体的射流管伺服阀的结构及工作原理,对射流管伺服阀的动态响应特性进行了试验研究,介绍了试验原理,给出了相应的试验结果。The method of filling magnetic fluid into the working clearances of jet - pipe servo valve to improve the dynamic response of jet - pipe servo valve was presented. The construction and working principle of jet - pipe servo valve with magnetic fluid were introduced. The experiments of jet - pipe servo valve dynamic response characteristics were carried out. The experimental results were compared when the magnetic fluid is used or not in the servo valve.
