Abstract
A hinge for the controlled rotatable movement of a closing element anchored to a stationary support structure includes a pivot, a hinge body and a hydraulic damping cylinder. The pivot has a first axis and includes a cam, and the hinge body is engaged to the pivot so as to be rotatably coupled to each other around the first axis. The hydraulic damping cylinder includes a jacket and a plunger element, and the jacket defines a second axis, houses a working fluid and is divided into a first and a second variable volume compartment in fluid communication with each other. The plunger has a first and a second end respectively inserted into the first and second variable volume compartment to slide sealingly in the jacket. The hinge body includes a working chamber defining a third axis that is substantially perpendicular to the first axis and contains an elastic counteracting member.
