ABSTRACT:
A hydraulically damped motor mount is provided comprising a bearing plate, annular resilient member and a bottom plate forming a working spaced filled with hydraulic liquid which is connected through a choke opening to a liquid filled equalization space of variable volume. Two grid plates are disposed between the working space and the equalization space. A thin partition is disposed between the two grid plates. The grid bars of both grid plates continuously rest against the partition. The partial regions of the partition associated with the grid openings are provided with a separation which comprises a cut having a maximum width of 0.2 times the thickness of the partition. The smalles width of each grid opening is about 2.5 to 25 times the thickness of the partition.
