ABSTRACT:
The support has a generally annular shape and a fixing device extends axially therethrough. It comprises an annular elastically yieldable mass connected to two frames, a semi-toric membrane fixed between the two frames and defnining with the outer surface of the mass a work chamber (A). This chamber communicates with an expansion chamber (B) through a passageway. The support also includes a device for limiting its axial and radial movements. Such a support has a particularly low natural stiffness both in the radial direction and in the transverse direction, which improves the filtering of high frequency vibrations while affording a good damping of trepidations of low frequency and large amplitude.
