Abstract
The present invention relates to an antivibration device intended to reduce the transmission of vibration between two bodies (2, 3). According to the invention, the antivibration device comprises an elastic annular element (4) which is connected to two bodies (2, 3) so as to serve as a connection between them and which is capable of being deformed under the action of vibration generated in at least one of the bodies, and a resonator (5) connected, via at least two leaves (6, 7) which are flexible in terms of bending and rigid in terms of tension and in terms of compression, to the internal face (8) of the annular element (4) so as to be set in oscillating rotation when the annular element (4) is deformed, by the action of vibration so that, by this oscillating rotation, the resonator (5) generates an antivibration inertia force which opposes the vibration and thus reduces its transmission from one body to the other.
