A hydraulic hinge device for a controlled rotary movement of a closing element (P), which can be anchored to a stationary support structure (S), the hydraulic hinge device comprising:
- a hinge body (110) configured to be integrally anchored to one of the closing element (P) and the stationary support structure (S);
- a pivot (200) configured to be integrally anchored to the other one of the closing element (P) and the stationary support structure (S), said pivot (200) defining a first axis (X), said hinge body (110) and said pivot (200) being mutually rotatably coupled to rotate one with respect to the other around an axis substantially parallel to or coincident with said first axis (X) between an opening position and a closing position of the closing element (P);
- control means (1) for controlling a flow of a working fluid, comprising:
- a first and a second hydraulic working chamber (11, 12) housing said working fluid, said first and said second hydraulic working chamber (11, 12) comprising a respective inlet port (13′, 14′);
- a line (15) for a fluidic connection of said first and said second working chamber (11, 12);
- an adjustment element (40) for adjusting the flow of the working fluid arranged in said fluidic connection line (15);
- a first and a second stem (20′, 20″) sealingly and slidably inserted into the respective inlet port (13′, 14′) to slide along a respective second and third axis (Y′, Y″), each of said first and said second stems (20′, 20″) comprising an end (21′, 22′) respectively disposed inside the first and the second hydraulic working chamber (11, 12) and an opposite end (21″, 22″) external thereto respectively slidable along the second and the third axes (Y′, Y″) between respective positions distal from and proximal to the respective inlet ports (13′, 14′);
- wherein said hinge body (110) internally includes a compartment (112) comprising said pivot (200), said compartment (112) further including said control means (1) or the control means being removably insertable into said compartment (112);
- wherein said working fluid is exclusively contained in said first and said second working chamber (11, 12) and said fluidic connection line (15), said compartment (112) comprising a dry portion (113) which includes said pivot (200) and the opposite ends (21″, 22″) of said first and said second stem (20′, 20″);
- and
- wherein said pivot (200) comprises a first and a second cam portion (215, 210) susceptible to dry-interact selectively and alternately with corresponding at least first and second cam followers (25′, 25″) integrally coupled respectively with said opposite ends (21″, 22″) of said first and said second stem (20′, 20″);
- whereby, to a mutual rotation of said hinge body (110) and said pivot (200) around said axis substantially parallel to or coincident with said first axis (X) between said opening position and at least said closing position of the closing element (P), there corresponds a sliding of one of said opposite ends (21″) along the respective second or third axis (Y′) from a respective distal position toward a respective proximal position and a simultaneous sliding of the other one of said opposite ends (22″) along the respective second or third axis (Y″) from the respective proximal position toward the respective distal position and vice versa.
