Hydraulic actuator and method for operating a hydraulic actuator

The hydraulic actuator comprises: a hydraulic input cylinder having an input piston; a hydraulic output cylinder, which is hydraulically coupled to the input cylinder; and a pressure-limiting valve, which limits the output cylinder with respect to pressure in dependence on the usability of a force o...

Beschreibung
Zusammenfassung:	The hydraulic actuator comprises: a hydraulic input cylinder having an input piston; a hydraulic output cylinder, which is hydraulically coupled to the input cylinder; and a pressure-limiting valve, which limits the output cylinder with respect to pressure in dependence on the usability of a force on the input piston. The method is a method for operating such a hydraulic actuator, wherein the drive actuator is deflected with deflections having a deflection duration at a deflection frequency for the duration of an acting or a non-acting phase of the hydraulic actuator, wherein the deflection duration defines a movement stiffness of the hydraulic actuator and the deflection frequency defines the resulting deflection speed of the hydraulic actuator.
