Abstract
A fluid-damped elastomeric bushing has an inner sleeve and an outer sleeve disposed outwardly of the inner sleeve, and two sidewalls extending between the inner sleeve and the outer sleeve and a partition wall to thereby form a pair of fluid compartments. The fluid compartments has a main chamber and a supplemental chamber in communication with the main chamber. An elastic support member extends radially outwardly from the inner sleeve toward the outer sleeve between the side walls to form a first main chamber and a second main chamber. An orifice device is disposed circumferentially along the outer sleeve for communicating the first and second main chambers for causing a fluid in one of the first and second main chambers to be forcibly fed to the other one of the first and second main chambers when a load is applied to the bushing.
