Abstract: An actuation unit includes an actuating arm pivotable between an open and closed position; a pneumatic cylinder comprising a stem movable linearly along a cylinder axis and configured to control pivoting of the actuating arm; and a closing device that includes a braking unit configured to brake movement of the actuating arm having a surface portion configured to come into contact with at least one braking assembly. The braking assembly is locked against rotation and axially movable between a non-braking and braking configuration. The surface portion is in a non-orthogonal arrangement with respect to the cylinder axis and the braking assembly includes a plurality of rollers retained in the braking assembly with clearance at least with respect to a radial movement thereof, the rollers being able to assume a first radial configuration not in contact with the surface portion and a second radial configuration in contact with the surface portion.

Abstract: An actuating device comprising a housing inside of which an actuating element is provided, the actuating element being slidably displaceable along a first axis between a first operative position and a second non-operative position, the displacement between the first operative position and the second non-operative position defining the stroke of the actuating element; a manual operating element pivotably connected to the housing at a first pivoting axis and coupled to the actuating element through a linkage, so that the linkage produces a translation of the actuating element, upon rotation of the manual operating element; the linkage comprising at least one lever arm coupled to a respective driver member, wherein the driver member is guided and constrained into a respective blind seat provided on the actuating element, characterized in that the lever arm is slidably coupled to the driver member and the driver member is movably constrained into the blind seat.

Abstract: An actuating device of the articulated lever or cam type having a body coupled to a sliding control piston, the piston coupled to an actuator movable along a piston axis and operatively coupled to a pivotable arm to pivot it about a first rotational axis upon a sliding movement of the actuator. The actuator has two relatively displaceable parts and one or more rotary elements having at least one mechanical coupling that acts on the first part of the actuator to transform a rotary control movement imparted on the at least one mechanical coupling about a second rotational axis transverse to the piston axis, into a relative displacement between the first part and the second part of the actuator along the piston axis to modify the length of the actuator.

Abstract: An actuating device which comprises a housing inside of which a slidably displaceable actuating element and sensing means adapted to detect the positioning of the actuating element are provided, wherein the actuating element is coupled to at least one triggering part and the housing comprises at least one reading opening through which the positioning of the at least one triggering part at at least one sensing position can be detected; further wherein the sensing means are placed outside the housing at the reading opening and the at least one triggering part is completely housed inside the housing, the at least one reading opening being sealed with a cover made of a material adapted to allow the detection of the triggering part when placed at the at least one sensing position.
