FIELD: engines and pumps.
SUBSTANCE: invention relates to machine building, particularly, to engine production. Proposed device comprises a cylindrical-ring flexible element made from coiled steel. The rope turns, arranged between the plates, are arranged perpendicular to the support axis at diametrically opposite points of spiral turn. The additional flexible element is arranged inside the main one. The main flexible element turns embrace those of the additional flexible element. The steel rope of the cylindrical-ring flexible element is made up of strands, while the additional flexible element is made up of untwisted strand of steel rope rolled in fake.
EFFECT: higher efficiency in wide frequency range.
