| Abstract: | A new structure of piezoelectric microvalve based on switching principle was designed via selection of piezoelectric actuator and dimension calculation of pressure chamber and throttling orifice.Based on the piezoelectric microvalve,a new type of electronic electric-pneumatic transfer was developed.Experimental results show the good capability of the transfer,which provides good basis of development of electric-pneumatic transfer with new piezoelectric structure. |
