Electro-hydraulic servovalve having mechanical feedback |
摘要 |
The invention is a multi-stage electro-hydraulic servovalve having a mechanical feedback between the valve's main and pilot stages. The feedback mechanism makes use of an interconnected set of linkages that transform a linear motion of the main stage slide into a rotative movement of a torque rod that can produce a translation of the pilot stage slide. Many of the linkages of the feedback mechanism are located exterior to the valve's fluid boundary and feature readily adjustable connections through which a user can adjust various parameters of the feedback such as the degree of gain and null point. |
