<p>The present invention refers to a hinge for doors having a spring with a damper, being made up by two cylindrical bodies (1, 2), solidarized respectively with the blades (3,4) for anchoring to the door and frame respectively. One of said cylindrical bodies (1, 2) constitutes a tight chamber (5), by means of closure and caps (6, 7), inside which is placed a piston (8) laterally related with the cylinder by means of longitudinal guides (9) which hinder the rotation of the piston (8). Said piston (8) presents an axial threaded pitch (10), through which it is left mounted in a spindle (11) with an ample thread pitch, which spindle (11) forms the extreme part of an axial shaft (12) which passes through a central perforation (13) of one of the closure caps (6) of said tight chamber (5). All of it is disposed in a mode that the rotation of the second cylindrical body (2) of the hinge through the coupling of its blade (4) corresponding to the door, performs a torsion effort of the spring (19), whilst a rotation of the central shaft (12) takes place in the tight chamber (5) which is occupied by an oleo-hydraulic fluid.</p> |
