The valve is driven directly by a large strake multilayer piezoelectric stack, its displacement actuates the power cascade spool after amplification by a lever mechanism.
该阀采用大行程的压电叠堆作为驱动元件，经杠杆放大后的位移直接驱动功率级滑阀。
The new motor-driven devices of valve based on analyses above have been successfully used in industry production.
基于上述分析而重新设计的阀门电动装置已成功用于工业生产。
Driven through the solenoid valve coil, only on or off, the switch moves a short time.
电磁阀通过线圈驱动，只能开或关，开关时动作时间短。
