Abstract

Described is 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 second 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);an outer conduit (31, 32), connected to the re-entry chamber (23) of the second cylinder (C2) for allowing the supply and discharge of oil.The outer conduit (31, 32) comprises:a first body (31), comprising a first slider (31a) slidable in a sealed fashion in a first sleeve (31c) constrained to the second piston (21);a second body (32), comprising a second slider (32a) slidable in a sealed fashion in a second sleeve (32c) which is constrained to the second jacket (A2) and is in fluid communication with the re-entry chamber (23) of the second cylinder (C2), said second slider (32a) being constrained to the first sleeve (31c);wherein the first slider (31a) comprises a first inner channel (310) which emerges in the first chamber (31b); wherein the second slider (32a) comprises a second inner channel (320) which emerges in the second chamber (32b);wherein the first chamber (31b) is in fluid communication with the second inner channel (320).
