Abstract (en)
[origin: WO2008155480A1] The present invention relates to a multiple-acting linear actuator (100) intended to drive at least two elements capable of moving relative to a fixed element comprising a plurality of rod-forming concentric tubular bodies (103, 102, 104) engaged successively one inside the next via external and/or internal screw threads (105, 106, 107, 108), characterized in that one of the bodies is connected to rotational-drive means (109), the other bodies then together forming an internal and/or external transmission train, and in that said bodies are associated with selective lock-up means whereas the outermost bodies of the internal and/or external transmission trains are permanently prevented from rotating.
