Hydraulic shock absorber for automatic closing of doors, essentially characterized by carrying an eccentric connecting rod, mounted on an axle (which is the same as that of the door). The turns of this axis are transformed by the connecting rod, in a compression or decompression of a helical spring, whose axis is perpendicular to that of rotation, being in the same plane.
