摘　　要：电液转换器的选型是DEH系统设计的关键问题之一,在实际应用中选择的主要是MOOG阀和DDV阀,它们各有优缺点。就响应时间、流量、灵敏度和油质这4项指标对G761型MOOG阀和D634型DDV阀在透平油压力为4MPa下的性能进行分析和对比,得出了一些结论,可供选用时参考。The selection of the Electro hydraulic Servo is one of the serious factors in the design of the DEH system. We select MOOG and DDV as the Electro hydraulic Servo in the practical application, they have respect merits and faults. The analysis and comparison on the performance of MOOG and DDV in the 4MPa of the oil pressure in the four indexes of the respense time, flow, sensitivity, and oil quality are indicated, then draw some useful conclusion.
