Abstract (en)
A fluid operated actuator comprising a cylinder (10) a piston (17) reciprocable in said cylinder (10) a screw shaft (19) rotatably supported in the cylinder (10), said screw shaft (19) axially extending through and being threadly engaged by said piston (17) for rotation during relative axial movement between said piston (17) and said cylinder (10); a centrifugally controlled and fluid actuated braking device (31, 32; 38) is provided for retaining said screw shaft (19) from rotation to lock the relative movement between the piston (17) and the cylinder (10) of the actuator. <IMAGE>
