A hydraulic damper (100) comprises a cylinder (10) with a bottom wall (11), a head wall (12) and side walls (13) that define a damping chamber (15) containing a damping fluid (17); in the damping chamber (15) a piston (20) slides with a first face (20a) and a second face (20b) opposite to each other. In particular, the piston (20) defines a first chamber (21) and a second chamber (22) separate from each other and is integral to a shaft (25) with an external connection end (36). The piston (20) is suitable for carrying out a forward stroke (A), between a first dead point (BDP), towards a second dead point (TDP) and a back stroke (B) between the second dead point (TDP) and the first dead point (BDP). In particular, the piston (20) comprises a plurality of permanent holes (33) suitable for permanently connecting the first chamber (21) and second chamber (22) and a plurality of apertures (26) associated each to a plurality of plug elements (37) pivotally connected by connection means (40), on a face of the piston (20) at the apertures (26). The plug elements (37) are suitable to pass spontaneously from a closed configuration (C), in which they close the apertures (26) and allow the leakage of the damping fluid (17) through the plurality of permanent holes (33), in order to damp the movement of the piston (20), to an open configuration (D), in which they open the apertures (26) and allow the free passage of the damping fluid (17) between the first (21) and second chamber (22) allowing a substantial passage of the damping fluid (17) between the first (21) and second chamber (22), in order to reduce the time that takes the piston (20) in the return stroke to return to the starting position BDP.
