AbstractA fluid-sealed mounting comprises a base adapted to be secured to a vehicle body frame, for example, an attachment adapted to be connected to a source of vibrations, a first elastic member connected to the base and the attachment, a fluid chamber defined at least partly by the base, the attachment, and the first elastic member, and filled with a fluid, a partition dividing the fluid chamber into first and second chambers, and an orifice providing communication between the first and second chambers. The partition comprises a second elastic member connected to the base and the attachment. The rate of flow of the fluid through the orifice between the first and second chambers at the time the first elastic member is vibrated is different from the rate of flow of the fluid through the orifice between the first and second chambers at the time the second elastic member is vibrated.
