ABSTRACT:
A piezoelectric fluid pumping apparatus includes pumping means for supplying a fluid under pressure and an energizer arranged in driving relationship therewith. The energizer includes a generally planar flexure member having first and second piezoelectric laminates supported thereon. The flexure member includes a first edge and a second edge, the edges being resiliently constrained for substantially preventing longitudinal movement thereof when an electrical signal is applied to the laminates. Preferred embodiments of the flexure member include bimorphous, biunimorphous and quadrimorphous piezoelectric structures.
