ABSTRACT:
The present invention covers a door hinge equipped with a damper spring, composed of two cylindrical bodies, kept in place by their anchor plates with the door, respectively the door frame. One of the cylindrical bodies forms a watertight chamber by way of sealing plugs, inside which a piston is mounted, held laterally in the cylinder by longitudinal guides which prevent the piston from rotating. Said piston has a threaded axial bore by which it is mounted on a journal with a wide screw pitch, the journal being the end of an axial shaft which passes through a central perforation in one of the sealing plugs of the watertight chamber. All this is so designed that the turning of the second cylindrical body of the hinge caused by its being fixed to the door by its respective anchor plate, creates a torsion stress in a spring, while at the same time turning the axial shaft in the watertight chamber filled with oil-hydraulic fluid.
