The actuator unit (1) comprises a hollow body (2) defining a sliding chamber inside (3, 103, 203); a piston (4) mounted sliding inside said sliding chamber (3, 103, 203) in such a way as to provide an actuation force (F) and operated by a fluid fed from outside; a body (6) having one transmission end (6B) for the transmission of said actuation force prolonged outside said sliding chamber (3, 103, 203) and one hooking end (6A) hooked to said piston (4), amplification means (18, 21, 23) being interposed between said body (6) and said piston (4) to amplify said actuation force (f) so as to obtain an amplified actuation force (F1). |
