    New search for: CHERUBINI LIONELLO

    An emergency operation unit (12) for shutters (2) comprises a pinion (22), a crown (28), and unidirectional slowing and braking means suitable for slowing or stopping the rotation of the crown (28) according to a first direction of rotation (DOWN). The means comprise at least one torsion spring (48;48a,48b), a fixed cylinder (56";56a";56b") onto which the spring (48;48a,48b) is fitted, opening flaps (52") rotatably integral to the crown (28) and arranged between the spring ends (48',48'') to enlarge said spring (48;48a,48b), and closing flaps (54"), rotatably integral to the shutter movement, between which are arranged the spring ends (48',48") to tighten the spring (48;48a,48b) on the fixed cylinder (56";56a";56b"), generating a resistant torque.
