Claim:
1. A hinge for coupling a door and a stationary support structure, the hinge comprising: a fixed element to be coupled to the stationary support structure; a movable element to be coupled to the door, the fixed element and the movable element being rotatably coupled each other to rotate about a first longitudinal axis; wherein one of said movable element and fixed element includes a hinge body, the other of said movable element and fixed element including a pivot extending along said first axis; wherein said pivot includes a cam member rotating about said first longitudinal axis, said hinge body including at least one working chamber extending along a second longitudinal axis perpendicular to said first axis, said at least one working chamber including a follower member reciprocally interacting with said cam member for sliding along said second longitudinal axis between a first end-stroke position and a second end-stroke position, said follower member including at least one elastic counteracting element; wherein said cam member includes at least one first cam element and at least one second cam element mutually superimposed along said first axis, the at least one first cam element being configured to move said follower member from one of said first and second end stroke positions to a third position which is intermediate therebetween and vice-versa, said at least one second cam element being configured to move the follower member from said third intermediate position to the other of said first and second end stroke positions and vice-versa; wherein said follower member includes at least one interface element interposed between said pivot and said at least one elastic counteracting element, said at least one interface element comprising at least one first operating surface and at least one second operating surface, said at least one first operating surface and at least one second operating surface being mutually superimposed to sequentially interact respectively with said at least one first cam element and with said at least one second cam element and vice-versa.
