1. A cable cylinder comprising a body, in which a screw is rotatably mounted so as to rotate about a longitudinal axis by being selectively driven by a motor, a nut cooperating with the screw so as to move in the body due to the rotational movement of the screw, the cylinder comprising a pair of upstream pulleys and a pair of downstream pulleys arranged on either side of the nut, such that in at least one of the pairs, the pulleys are rotationally secured to one another, and two cables each cooperating with one of the upstream pulleys and one of the downstream pulleys so as to define, for each cable, strands that are parallel to the axis of rotation of the screw, which are attached to the nut, wherein one of the cables forms a loop between its upstream pulley and its downstream pulley, while the other of the cables is extended beyond its downstream pulley to cooperate with a remote pulley rotatably mounted so as to rotate about a remote axis of rotation, separate from the axis of rotation of the downstream pulley, the remote pulley forming a return to return the extended cable to the upstream pulley, the extended cable being prevented from sliding over at least that of its upstream or downstream pulley that is rotationally secured.
