<p>An actuator of the screw-nut type for converting a rotary input movement into a rectilinear output movement between two fixed end positions; …<??>According to this invention, the rotary input movement is transmitted to the screw shaft (176) through a linkage comprising a clutch mechanism (206) and a torsion bar (214), the two clutch elements (208, 210) being frictionally engaged under the force of an axial compression spring (212), and cam means (268, 274) being further provided for expanding the spring and thus disengaging the clutch elements when the torsion of bar (214) reaches a predetermined amount; …<??>For use particularly in jet aircraft thrust reversers.</p> |
