Abstract:
(EN) The invention relates to a piezohydraulic actuator (10) comprising at least one piezo actuator (12), at least one drive (14), and at least two outputs (32, 44) hydraulically coupled to the drive (14) and mechanically coupled to one another, thus allowing a switch between at least two operational modes of the actuator (10) in a particularly advantageous and simple manner.
(FR) La présente invention concerne un actionneur piézohydraulique (10) comprenant au moins un actionneur piézoélectrique (12), au moins un entraînement d’entrée (14) et au moins deux entraînements de sortie (32, 44) couplés hydrauliquement à l’entraînement d’entrée (14) et couplés mécaniquement entre eux de sorte qu’une commutation peut être réalisée de manière particulièrement avantageuse et simple entre au moins deux modes de fonctionnement de l'actionneur (10).
(DE) Piezohydraulischer Aktor und Verfahren zum Betreiben eines solchen piezohydraulischen Aktors Die Erfindung betrifft einen piezohydraulischen Aktor (10), mit wenigstens einem Piezoaktor (12), mit wenigstens einem Antrieb (14), und mit wenigstens zwei hydraulisch mit dem Antrieb (14) gekoppelten und mechanische miteinander gekoppelten Abtrieben (32, 44), sodass auf besonders vorteilhafte und einfache Weise zwischen wenigstens zwei Betriebsmodi des Aktors (10) umgeschaltet werden kann.
