压电晶体型电液开关阀

Multilayed Piezoelectric ElectroHydraulic OnOff Valve

根据压电晶体的逆压电效应，设计了粘接式多层压电晶体电－机械转换器及其驱动电路．在此基础上设计了压电晶体型电液开关阀，进行了压电晶体型电液开关阀的开启特性实验．

According to the antipiezoelectric effect, an adhered multilayer piezocrystal electromechanical transducer and its drive circuit have been designed. Based on this, the multilayer piezocrystal electrohydraulic onoff valve have also been designed, and then the onoff characteristic experiment of this valve has been completed.
