A friction shock absorber having a thin wall cylinder filled with compressible solid, an outer sleeve fitted over and slidably engaging the thin wall cylinder, with the wall thickness of the outer sleeve being approximately three times greater than the wall thickness of the thin wall cylinder, and a piston rod extending into the thin walled cylinder having a piston head in engagement with the inner surface of the cylinder, with the piston head being provided with a multiplicity of axially disposed orifices. When subject to relatively high impact forces, the wall of the cylinder expands radially into tighter frictional engagement with the wall of the outer sleeve and a peripheral orifice is thus obtained for additional throttling of the compressible solid, thereby increasing the shock dissipating capacity of the shock absorber.
