Abstract
The invention relates to a hydraulic vibration damping bushing comprising two tubular rigid armatures (1, 2) jointly united by an elastomeric body (3) configured in such a way to form between themselves at least two tight pockets (4, 4') communicating with each other by a narrow channel (7), which along with the pockets is filled with a liquid. One of these pockets (4) contains an elastomeric pad (10) added on the concave face of a curved rigid plate (11) which abuts on the internal face of the external armature (2), said pad being, in the resting position of the bushing, diametrically precompressed between the two armatures.
