The present invention relates to a device for mounting a carried element on a carrying element in an automotive vehicle or the like. The device comprises a resiliently deformable support secured to two frame members so as to define a fluid-tight chamber, the chamber containing a fluid and being divided into two portions by a separating partition formed of a resilient annular portion affixed to one frame member and which carries a block member having at least one orifice through which the fluid is adapted to pass from one chamber portion to the other. The block member has a certain inertial mass such that the resilient portion will oscillate substantially following the displacement of the carried element when the latter vibrates at a frequency less than a particular frequency but will oscillate independently of the displacement of the carried element when the latter vibrates at a frequency greater than the particular frequency. In this manner, the fluid flow pattern through the orifice during high frequency vibrations is inverted relative to normal conditions thereby reducing vibration damping and reducing noise. |
