  • Elastic mount having fluid chamber partially defined by elastically supported oscillating plate
    Patent number: 5277409
    Abstract: A fluid-filled elastic mount wherein an elastic body elastically connecting a first and a second support partially defines a fluid chamber filled with a non-compressible fluid. The elastic mount includes an oscillating plate which partially defines the fluid chamber and which is supported by the second support such that the oscillating plate is displaceable relative to the second support, and an actuator for oscillating the oscillating plate to thereby change a pressure of the fluid in the fluid chamber. The elastic mount further includes an elastic support member for flexibly connecting the oscillating plate to the second support such that the oscillating plate is movable toward and away from the fluid chamber. This elastic support member is formed of an elastic material which substantially permits shearing deformation of the elastic support member and inhibits its compressive and tensile deformation.
