ABSTRACT:
A viscous spring damper for damping and levelling structural agitation comprising a first outer member joined to a connecting member by a first elastomeric shear spring, the first outer member including a first fluid chamber and a first elastomeric diaphragm. A second outer member is joined to the connecting member by a second elastomeric shear spring and includes a second fluid chamber and a second elastomeric diaphragm. The connecting member is comprised of a plurality of elastomeric flexible sections which are disposed to form a main fluid chamber communicating with the first fluid chamber and the second fluid chamber, and further includes restrictive orifice for restricting the flow of fluid in the main fluid chamber.
