动态压力反馈伺服阀在动态条件下的功能类似于压力流量控制阀,但在稳定状态下(或静态)却与纯流量控制阀的作用类似。因而这种压力反馈的优点不但在于其给谐振负载提供了阻尼,而且在静态时仍能为系统保留流量控制阀所能得到的高分辨率和刚度特性。
Dynamic pressure feedback servo valves function similarly to pressure flow control valves under dynamic conditions but function similarly to pure flow control valves at steady state (or static). The advantage of this pressure feedback is therefore not only that it provides damping of the resonant load but also retains the high resolution and stiffness characteristics of the flow control valve for the system at rest.
