ABSTRACT:
A hydraulically damped mount includes a mounting element fixed to a moving component and a support fixed to a stationary component. A resilient element is connected between the mounting element and the support and cooperates with a diaphragm to define a fluid chamber. The fluid chamber is divided into a working chamber and a compensation chamber by a partition assembly. The partition assembly has an upper plate and a lower plate joined together to define a space within which a movable plate is vertically movable to absorb movement of the fluid caused by a change in pressure in the working chamber. A spacer is centrally disposed in the upper and lower plates to provide a constant distance therebetween.
