PIEZOHYDRAULIC ACTUATOR AND METHOD FOR OPERATING SUCH A PIEZOHYDRAULIC ACTUATOR

摘要

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.
