Abstract: A hinge device includes a fixed element, a movable element, and a slider. One of the fixed or the movable elements defines a working chamber receiving the slider, and the other one has a pivot causing the slider to slide upon a rotation of the pivot. The working chamber contains a working fluid and is separated into a first and a second variable volume compartments by a plunger of the slider, which includes a first valve providing fluid communication between the compartments. A first duct passing through a closing cap of the working chamber has a second valve in fluid communication with the first and second compartments and spaced from the plunger for a first part of a stroke of the plunger. During a second part of the stroke, the plunger acts upon the second valve to cause the closing element to latch toward an open or closed position.
