  • Shock absorber
    Patent number: 4026534
    Abstract: A shock absorber having alternate layers of a viscoelastic material and thin leaf springs disposed between, and having each end mounted on a pair of parallel side members which are disposed to undergo translative movement when the shock absorber is forced into either a compressed or an extended position. The layers of viscoelastic material and leaf springs are loaded as fixed end beams in the compressed and extended position, and return to the neutral position because of the spring constant in the leaf springs when a load is removed.
