Patent ID: 8016274

Claim:
An antivibration device disposed for supporting loads and damping vibration between two external elements, comprising: first and second rigid members for securing respectively to each of said external elements; a resilient body connecting together said first and second rigid members and being disposed for at least partially supporting said loads and at least partially damping said vibrations; a damping unit for further partially damping said vibrations coincidentally with said resilient body, comprising at least one flexible wall fixed to said second rigid member; a solid pushing member rigidly fixed to said first rigid member for pushing said flexible wall in order to transfer loads and vibrations to said damping unit; and an inhibitor apparatus operable to drive the damping unit between: a first position in which the flexible wall is sufficiently close to the pushing member to be pushed by said pushing member when said first rigid member is moved in a direction corresponding to a compression of the resilient body, whereby said pushing member is thus able to transfer loads and vibrations to said damping unit, and a second position in which the flexible wall is sufficiently distant from the pushing member to not be pushed by said pushing member when said first rigid member is moved in a direction corresponding to a compression of the resilient body, whereby said pushing member is thus unable to transfer any loads and vibrations to said damping unit.
