ABSTRACT:
A piezoelectric valve for controlling fluid flow through valve ports comprises a fluidtight valve body and a diaphragm. The valve body defines valve ports, and the diaphragm includes a plurality of piezoelectric members, the members being adapted to be selectively piezoelectrically deflected in opposite directions in a plane of operation thereof to produce a cumulative excursion to selectively block or unblock the valve ports. The enhanced cumulative excursion enables valve ports of greater cross-sectional area to be employed.
