Direct action type 2D electro -hydraulic pressure servo valve

The utility model relates to a direct action type 2D electro -hydraulic pressure servo valve. Its characterized in that comprises valve body module, electromechanical converter module, drive mechanism module and displacement sensor module, and the displacement sensor module cooperatees with the valve body module, and the electromechanical converter module cooperatees through drive mechanism module and valve body module, the displacement of 2D piston and the rotary electromagnet signal of telecommunication of electromechanical converter module constitute the closed loop feedback in the displacement sensor module real -time supervision valve body module. The utility model discloses a control rotary electromagnet's deflection angle changes the axial displacement distance of case, and then the size that changes the spring force comes adjustment system's pressure, has structurally simplified original two -stage or multiple -order structural style greatly, accords with the simple compact requirement of trade. 本实用新型
