Abstract: A two-way fluid actuator assembly (100) comprising: a first cylinder-piston device (10) comprising a first cylinder (12) and a first piston (11) sliding inside said first cylinder (12) along a first axis (PA), forming a first variable-volume chamber (14) between said first cylinder (12) and said first piston (11) as a function of a relative position between said first cylinder (12) and said first piston (11), a first rolling-diaphragm fluid-tight element (13) between said first cylinder (12) and said first piston (11); a first hydraulic pipe (8) having a first end communicating with said first variable-volume chamber (14); a second cylinder-piston device ((2200)) comprising a second cylinder (22) and a second piston (21) sliding inside said second cylinder (22) along a second axis (SA), forming a second variable-volume chamber (24) between said second cylinder (22) and said second piston (21) as a function of a relative position between said second cylinder (22) and said second piston (21), a second rolling-diaphragm fluid-tight element (23) between said second cylinder (22) and said second piston (21); a second hydraulic pipe (9) having a first end communicating with said second variable-volume chamber (24); a linear actuator device (5) comprising a translating element (1) arranged to translate along a translation axis (T) wherein the remaining movements of said translating element (1) are prevented, a rotating element (2) arranged to rotate about said translation axis (T) constrained in all remaining movements, wherein the translating element (1) and the rotating element (2) are engaged with each other by means of a helical kinematic couple, the linear actuator device (5) comprising an electric motor (3) connected to said rotating element (2) to rotate said rotating element (2), wherein said first cylinder-piston device (10) and said second cylinder-piston device (20) are connected to said translating element (1) on opposite sides with respect to the translation direction (T) so that a translation of said translating element (1) corresponds to a compression of one of said first variable-volume chamber (14) and said second variable-volume chamber (24) and a simultaneous expansion of the other of said first variable-volume chamber (14) and said second variable-volume chamber (24).
