A hinge for the controlled rotatable movement of at least one closing element, such as a door, a door leaf or the like, anchored to a stationary support structure, such as a wall, a floor, a frame or the like, includes a hinge body and a pivot defining a first axis and reciprocally coupled to allow rotation of the at least one closing element between an open position and a closed position. The hinge further includes a working chamber defining a second axis substantially perpendicular to the first axis and a plunger element sliding in the working chamber along the second axis between a position proximal to the bottom wall of the working chamber and a position distal therefrom. |

1. A hinge for controlled rotatable movement of at least one closing element anchored to a stationary support structure, the hinge comprising:
a hinge body anchorable to one of the stationary support structure or the at least one closing element and at least one pivot defining a first axis anchorable to the other one of the stationary support structure or the at least one closing element, said pivot and said hinge body being reciprocally coupled to allow the at least one closing element to rotate between an open position and a closed position; at least one working chamber within said hinge body defining a second axis, said at least one working chamber including a bottom wall; and at least one plunger element sliding in said working chamber along said second axis between a position proximal to said bottom wall of said at least one working chamber and a position distal therefrom, said at least one plunger comprising a cylindrical body; wherein said at least one working chamber further includes a working fluid acting on said at least one plunger element for hydraulically damping an action thereof, said cylindrical body being inserted in said at least one working chamber for dividing thereof into at least one first and a second variable volume compartment in fluidic communication with each other, wherein the cylindrical body includes at least one first passage to allow the passage of the working fluid between said at least one first and second compartment upon one of the opening or closing of the at least one closing element, a circuit being provided for the passage of the working fluid between said first and second compartment upon the other of the opening or closing of the at least one closing element, wherein said circuit includes an adjusting screw inserted through said hinge body, the adjusting screw comprising a first upper threaded end screwed in a corresponding first upper counterthreaded connecting portion of said hinge body and a second lower end slidably inserted in a corresponding second lower guide portion of the hinge body, the second lower end being tightly inserted into the corresponding second lower guide portion of the hinge body, wherein said second lower end including a hollow seat housing a substantially frustoconical element coaxially inserted therein, said adjusting screw including a first opening for letting said working fluid in and out, an inner surface of said hollow seat facing an outer surface of said substantially frustoconical element to define an interspace therebetween which is fluidically connected to said first opening for letting said working fluid in and out and to said circuit, said interspace being interposed therebetween, and wherein said hollow seat has a substantially cylindrical shape, said substantially frustoconical element having a smaller diameter end faced to said first opening for letting said working fluid in and out so that unscrewing or screwing said first upper end of said adjusting screw from or in said first upper connecting portion of said hinge body corresponds to a mutual distancing or approaching of said substantially frustoconical element and said adjusting screw, so as to define an adjusting valve for adjusting the passage of the working fluid. |
