摘要
介绍了一种新型的压力先导控制伺服阀,该阀的功率放大级采用双阀芯结构代替传统单阀芯结构。通过分析其工作原理及相关特性,得知该阀适用于工程机械的液压控制系统中,且其制造装配工艺简单,是一种廉价的伺服阀。
A new servovalve using a pressure control pilot state was introduced, which uses two spools instead of single spool in power magnifying stage. Its working principle and relative characteristics was analyzed, it is indicated that this servovalve is suitable for the hydraulic control system of engineering machine, and it is easv to make or assemble, so it is a cheap servovalve.
