Abstract
An outer supporting body (2) surrounds an inner supporting body (1) at a radial distance therefrom, the bodies being supported on one another by a cushion (3) of rubber-elastic material which defines at least three chambers (4, 5, 6) filled with damping fluid. The first and the second chambers (4, 5) are connected to one another in a fluid-carrying manner by a connecting passage (7) and radially they at least partially surround the third chamber (6), which is defined toward the first and second chambers (4, 5) by diaphragm-like elastomeric walls.
