  • Low-power piezoelectric micro-machined valve
    Patent number: 7789371
    Abstract: A piezoelectric microvalve employs a valve element formed of hermetically sealed and opposed plates flexed together by a cross axis piezoelectric element. Large flow modulation with small piezoelectric actuator displacement is obtained by perimeter augmentation of the valve seat which dramatically increases the change in valve flow area for small deflections.
    Type: Grant
    Filed: May 31, 2007
    Date of Patent: September 7, 2010
