AN APPARATUS FOR MOVING FOLDED-BACK ARMS HAVING A PAIR OF OPPOSING SURFACES IN RESPONSE TO AN ELECTRICAL ACTIVATION

摘要

A piezoelectric actuator assembly for actuating industrial control valves or clamps provides a compact actuator including a single piece main structure with integrated hinge, mechanical lever, and spring in a shape such that in response to electrical activation, the piezoelectric device transfers mechanical energy from a predetermined axis into the force transfer member operably positioned for driving at least one pivotable arm portion in rotational movement.
