摘　　要：提出了数字阀控制主配压阀式电液系统的构成；分析了分别由二位三通数字阀和二位二通数字阀组成的电液系统的特点．实验表明数字阀控制主配压阀式电液系统具有较好的抗油污能力和理想的控制性能，是一种新型的调速器电液系统．This paper gives the electrohydraulic system piloted by digital valve. By analyzing the characteristics of the electrohydraulic system composed by 2 way 3 port digital valve and 2 way 2 port digital valve, it is concluded that the system controlled by digital valve has strong immunity of oil contamination and good control performance. It is a new kind of hydraulic system for speed governor.
