Hinge device comprising a fixed element (10), a movable element (11) and a slider (30, 60). One of the fixed element (10) and the movable element (11) comprises a working chamber (20) to slidingly house the slider (30, 60), the other of the fixed element (10) and movable element (11) comprising a pivot (50) reciprocally coupled with the slider (30, 60) so as the rotation of the movable element (11) corresponds to the sliding of the slider (30, 60) and vice versa. The working chamber (20) includes an end cap (27) and a working fluid. The slider (30, 60) includes a plunger member (30) that divides the working chamber (20) into a first and a second variable volume compartment (23, 24) fluidly communicating therebetween and preferably adjacent. The plunger member (30) comprises first valve means (32). The hydraulic circuit (100) includes a first duct (120) passing through the end cap (27) in fluid communication with both the first and the second compartment (23, 24). The end cap (27) includes an elongated tubular wall (28) extending within the working chamber (20). The hydraulic circuit (100) includes the interspace between the working chamber (20) and the elongated tubular wall (28). The latter is tightly inserted in the working chamber (20). The plunger member (30) is tightly inserted in the elongated tubular wall (28). The latter includes a first peripheral conduit (107) having a first port (102) in one of the first compartment (23) and the second compartment (24) and a second port (108) in fluid communication with the other of the first compartment (23) and the second compartment (24) through the first duct (120). |
