机电跟踪控制公用转阀变换系统

应用公用控制理论，设计出只有一组控制油孔控制多个油缸的公用转阀，此转阀体积小、工作可靠、加工容易。采用机电跟踪控制公用转阀变换系统，实现了机床变速的远距离集中控制，还可根据要求实现给定顺序的变换。系统具有结构简单、体积小、工作可靠等特点。

Electromechanic Tracing Control or Change System for Common Rotary Valve

Based on the common contrl principle, It is designed that a commom rotary valve controls multiple cylinders by only one group of control hole. The valve features conpact,reliable and easy to make. By use of electromechanic tracing controlled common rotary valve changing system, remote centering contrl of speeds of machine tools is realized and the speed can be changed according to the given sequence.
