Abstract: An actuation device (1) comprising a threaded shaft (2) connected at one end to driving means adapted to allow the threaded shaft (2) to rotate about its longitudinal axis (a). A movable element (3) is provided with a cylindrical cavity (30) adapted to receive the threaded shaft (2), and configured so that a rotation of the threaded shaft (2) corresponds to a translation the movable element (3) along the longitudinal axis (a). The device (1) has two guiding rods (4,4?) coupled to the movable element (3) and adapted to constrain the translation of the latter along a direction parallel to the longitudinal axis (a). Element (3) comprises a first (31) and a second (32) element constrained to each other, wherein the first element (31) is coupled to the threaded shaft (2) and the second element (32) is coupled to the two guiding rods (4,4?).

Abstract: An actuator (10) includes a body (12), an output member (14) slidably received in the body (12) along— a first axis (X1), an electric motor (18) arranged to set into rotation a motor shaft (20) about a, second axis (X2) and a motion conversion mechanism (22) for converting the rotary motion produced by the electric motor (18) about the second axis (X2) into a translational motion of the output member (14) along the first axis (X1). The motion conversion mechanism (22) includes a driving pulley (24) which is drivingly connected for rotation with the motor shaft (20) and an elongated mechanical transmission member which is wound onto the driving pulley (24) and is fastened at its two opposite ends to the output member (14) to draw this latter in either direction along the first axis (X1) as a result of the rotation of the driving pulley (24) in either direction. The output member (14) is shaped as a rod and is received in a cylindrical cavity (16) of the body (12) so as to project partially therefrom.
