Abstract

A telescopic cylinder, comprising:a first cylinder (C1), comprising a first piston (11) slidable in a sealed fashion in a jacket (A1) which comprises an extension chamber (12) and a re-entry chamber (13), separated from each other by a head (11a) of the first piston (11);a second cylinder (C2), comprising a second piston (21) slidable in a sealed fashion in a jacket (A2) which comprises an extension chamber (22) and a re-entry chamber (23), separated from each other by a head (21a) of the second piston (21);wherein the jacket (A1) of the first piston (11) is integral with the second piston (21);a conduit for connection to the extension chamber (22) of the second cylinder (C2) which is made at least partly through said first piston (11) and said second piston (21);a compensating device (100), provided with a control module (M) configured for adjusting a flow rate of operating fluid to be fed to the extension chamber (22) or discharged from the extension chamber (22) of the second cylinder (C2) as a function of a variation of volume per unit time of the extension chamber (12) of the first cylinder (C1).
