Apparatus for moving folded-back arms having a pair of opposing surfaces in response to an electrical activation

摘要

A pizoelectric 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 with a loss of motion of less than 40%.
