Hydraulically damping elastic bearing

Hydraulically dampimg elastic motor mount bearing for a motor vehicle, said bearing comprising:

• a body having first end means for fastening said bearing to a first structure and a second end means for fastening said bearing to a second structure;
• elastomeric means joining said first end means and said second end means;
• said elastomeric means also forming cavity means within said body;
• partition means dividing said cavity means into two chambers;
• damping fluid being contained in said two chambers;
• throttle means connecting said first and second chamber;
• controllable electromagnetic means for changing at least one suspension characteristic of said bearing, said controllable electromagnetic means being disposed to form at least a part of said partition means and comprising coil means and armature means, said armature means having at least one passage extending through said armature means for forming a bypass between said two chambers;
• valve means disposed in said at least one passage;
• and
• mechanical means disposed at one of said end means for mechanically opening said valve means.
