Resilient support device

Claim 1

A resilient support device for mounting an oscillating body on a support structure, of the type including: a tubular support body fixable to the support structure; an attachment member attachable to an oscilliating body and connected coaxially to one end of the tubular support body; an annular elastomeric element having its outer surface fixed to the tubular support body and its inner surface fixed to the attachment member to connect the latter to said one end of the support body, and a fluid-dynamic damper for damping oscillations of the attachment member relative to the tubular support body, wherein the improvement consists in: a rigid transverse wall being provided at the opposite end of the tubular support body to the attachment member; a shank being provided on the attachment member, and extending coaxially in the tubular support body, a transverse disk being carried at the inner end of said shank, and an annular elastomeric diaphragm interposed between the attachment member and the transverse disk so as to be coaxial with the tubular support body and axially spaced from said annular elastomeric element, said diaphragm being connected at its inner surface to said shank and at its outer surface to the tubular support body, a first chamber being defined between said diaphragm and said transverse wall of the tubular support body, and a second chamber being defined between said diaphragm and the annular elastic element, said first chamber being filled with a damping liquid in which the transverse disk is immersed and sealed with respect to said second chamber.
