ABSTRACT:
A dry friction shock absorber including a casing having an internal surface, a piston of low coefficient of friction bearing material having an external surface in contiguous relationship with the internal surface of the casing, attachment fittings on the piston and the casing for moving the piston into the casing when the shock absorber is subjected to shock forces, and expanding structure within the piston for tending to move the external surface of the piston outwardly toward the internal surface of the casing to increase the friction therebetween when the shock absorbing force is applied to the shock absorber for moving the piston into the casing. Adjustment structure is provided for varying the expanding force on the piston. A shock absorber of the foregoing type wherein the expanding structure is not activated when the piston moves slowly relative to the casing but which produces an expanding force on the piston when the shock absorber is subjected to shock forces both in tension and compression.
