PURPOSE: To simplify a rigidity decoupling over a short stroke by supporting the rigidity decoupling on an internal fastening ring on its inner surface confined in air, and on its outer surface on a cone integrated with the internal fastening ring, with the outer surface held in contact with damping liquid. CONSTITUTION: An elastic device comprises a sleeve with a side wall 11 capable of deformation accompanied by pressure reduction damping that utilizes radial elasticity produced by circulation of liquid between two upper and lower chambers 13, 14 through an elongate annular passage 10 formed around an external fastening round armature 1. A rigidity decoupling, over a short stroke, is secured by deformation of a thin wall 8 closing the chambers 13, 14, i.e., by geometrically limited deformation as the thin wall 8 confined in air is supported on an internal fastening ring 6 on its inner surface and on its outer surface on a cone 20 integrated with the internal fastening ring 6 with the outer surface held in contact with the damping liquid. |
