Abstract: The invention relates to a telescopic actuator comprising a rod (4), a hollow lead screw (5), a fixed piston (9) comprising a first tail (10) which extends in the lead screw (5) and a head (11). According to the invention, the actuator comprises a first hydraulic connection channel (16) extending through the first tail (10) to fluidically connect a first chamber (C1) with a source of hydraulic fluid (17), and the channel (16) comprises first damping means suitable for slowing down the rod (4) when the latter is depressed by regulating a hydraulic fluid flow rate in the first channel provoked by the depression of the rod.
