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 (14) transfers mechanical energy from a predetermined axis into the force transfer member operably positioned for driving at least one pivotable arm (18, 20) portion in rotational movement.

La présente invention concerne un ensemble actionneur piézoélectrique compact destiné à commander des vannes de réglage ou des dispositifs de serrage industriels, lequel ensemble comprend une structure principale monobloc à charnière intégrée, un levier mécanique et un ressort d'une forme telle qu'en réponse à une activation électrique, le dispositif piézoélectrique transfère de l'énergie mécanique en provenance d'un axe prédéterminé à l'organe de transfert de force fonctionnellement positionné afin d'entraîner au moins une partie bras pivotante en un mouvement de rotation.
