PIEZOELECTRIC ACTUATOR FOR MOVING FOLDED-BACK ARMS

摘要

A piezoelectric actuator assembly for actuating industrial control valves orclamps provides a compact actuator including a single piece main structurewith integrated hinge, mechanical lever, and spring in a shape such that inresponse to electrical activation, the piezoelectric device (14) transfersmechanical energy from a predetermined axis into the force transfer memberoperably positioned for driving at least one pivotable arm (18, 20) portion inrotational movement.
