Abstract

The invention relates to a telescopic actuator comprising a rod (), a hollow lead screw (), a fixed piston () comprising a first tail () which extends in the lead screw () and a head (). According to the invention, the actuator comprises a first hydraulic connection channel () extending through the first tail () to fluidically connect a first chamber (C) with a source of hydraulic fluid (), and the channel () comprises first damping means suitable for slowing down the rod () when the latter is depressed by regulating a hydraulic fluid flow rate in the first channel provoked by the depression of the rod.
