ABSTRACT:
A mount for securing together two relatively displaceable bodies, such as a motor-vehicle engine and a vehicle chassis, with limited relative freedom of movement has a substantially closed liquid-filled chamber formed by a first resiliently deformable wall and a second wall which may be rigid or resiliently deformable. A partition subdivides this chamber into a pair of compartments and has an elastically deformable and relatively stiff portion and an elastically deformable and relatively yieldable portion. One of these portions is formed with a throughgoing orifice. Stops are provided on each side of the relatively yieldable portion to limit the deflection thereof so that low-amplitude vibrations are not transmitted between the bodies, but high-amplitude vibrations are damped when the yieldable portion abuts the stops.
