Abstract: A self-activated no-back device includes a housing, an input shaft, an output shaft, a reactor hub, first grooves, a brake hub, second grooves, a plurality of balls, a reactor plate, a brake pack, a reactor spring, and a load spring. The first grooves are formed on an interior side of the reactor hub interior side, and the second grooves are formed in an interior side of the brake hub. Each second groove is aligned with a different first groove to define a plurality of groove pairs. Each ball is positioned in a different one of the groove pairs. One side of the reactor plate contacts the reactor hub. The brake pack is selectively contacted by the brake hub. The reactor spring supplies a spring force to the reactor plate, and the load spring supplies a spring force to the brake pack.
