Abstract
An engine mount is described as having two concentrically disposed annular resilient rubber springs, the outermost of which is provided with a pair of cavities and connecting passageway for receiving a dampening fluid. The spring rates of the two rubber springs can be individually tuned by the use of voids or cavities. Thus, there is a threefold manner in which the spring rate of the engine mount can be tuned.
