A hinge device includes a first fixed tubular half-shell having a working chamber defining a longitudinal axis, a second tubular half-shell rotatable about the longitudinal axis, a pivot rotating unitarily with the latter which includes a single pass-through actuating member having a helical shape, a plunger member slidable along the longitudinal axis, and a tubular bushing having a pair of guide cam slots. A pin inserted within the pass-through actuating member is provided to allow the mutual engagement of the pivot and the bushing. The first tubular half-shell includes an end portion susceptible to rotatably support the pivot, the second tubular half-shell and the bushing are coaxially coupled to each other, and the bushing and the first tubular half-shell are mutually unitarily coupled. |

1. A hinge device configured to rotatably move or check during closing or opening a closing element anchored to a stationary support structure, the hinge device comprising:
a fixed element anchored to the stationary support structure; a movable element anchored to the closing element, said movable element and said fixed element being mutually coupled to rotate about a first longitudinal axis between an open position and a closed position; and a slider movable along a second axis between a first end-stroke position, corresponding to one of said open and closed positions, and a second end-stroke position, corresponding to the other of said open and closed positions, wherein one of said fixed element or movable element comprises a working chamber defining said second axis for slidably housing said slider, the other one of said fixed element or movable element comprising a pivot defining said first axis, said pivot and said slider being mutually coupled so that a rotation of the movable element around said first axis corresponds to a at least partly sliding of the slider along said second axis and vice-versa, wherein said working chamber includes a working fluid acting on said slider to hydraulically counteract an action thereof, said slider including a plunger member configured to separate said working chamber in a first and a second variable volume compartment fluidly communicating with each other, said plunger member comprising a pass-through opening to put in fluid communication said first compartment and said second variable volume compartments and a valve member interacting with said opening to allow a passage of the working fluid between said first compartment and said second compartment during one of the opening or closing of the closing element and to prevent a backflow thereof during the other of the opening or closing of the closing element, a hydraulic circuit being provided to allow the passage of the working fluid between said first compartment and said second compartment during the other of the opening or closing of the closing element, wherein said hydraulic circuit includes a channel external to said working chamber defining a third axis substantially parallel to said first or said second axis, said channel having a first opening in said first compartment and a second opening in said second compartment which is proximal to said first opening, said channel further including a third opening in said second compartment distal from said first opening, wherein said plunger member is in a spatial relationship with said second and third openings of said circuit such to remain fluidly decoupled from said third opening for an entire stroke of the plunger member and such to remain fluidly coupled with said second opening for a first part of said stroke and to remain fluidly decoupled therefrom for a second part of said stroke, wherein a first regulating member for regulating a flow of said working fluid between said first compartment and said second compartment is further provided, said first regulating member including a rod defining a fourth longitudinal axis having an outer surface facing both said first and said second openings, said first regulating member being inserted in said channel to cause said third and fourth axis to be substantially parallel to or coinciding with each other, wherein an outer surface of said first regulating member includes a first portion facing said first opening and a second portion facing said second opening, said first regulating member further including an operative end to be operated from outside by a user to promote the rotation of said rod about said fourth axis between a working position, in which said second portion of the outer surface of the first regulating member selectively obstructs said second opening, and a rest position, in which the latter and said channel are in mutual fluid communication, said first portion of the outer surface of said first regulating member being configured or dimensioned such that said first opening and said third opening are always in mutual fluid communication through said channel regardless of whether the rod is in the rest position or in the working position, and wherein said channel includes a seat for said first regulating member that includes said first and said second openings, said seat having a first portion at said first opening having a first maximum diameter and a second portion at said second opening having a second maximum diameter, said first and second portions of the outer surface of said first regulating member including a respective third and fourth portion each having a respective maximum diameter laying respectively in said first and second portion of said seat. |
