ABSTRACT:
A hydraulically damped mounting device has two anchor points joined by a resilient spring. The resilient spring and a partition define a working chamber for liquid, the working chamber being in communication with a compensation chamber via a passage. The compensation chamber is bounded by flexible bellows. A flexible diaphragm defines, together with the partition a gas pocket. Relative movement of the anchor points causes a change in pressure in the working chamber. High frequency vibrations are absorbed by movement of the diaphragm with little resistance to movement. Low frequency vibration cause liquid movement through the passage with a strong damping effect. This affect may be controlled by suitable selection of the length and diameter of the passage. Preferably, a bleed orifice extends from the gas pocket to compensate for thermal changes in the volume of the pocket.
