Abstract
The hydraulically damped elastomer-metal bearing comprises a bell-type housing two rigidly connected truncated conical support springs, which are located in the housing and which are oriented in the same direction. Between the two support springs, a disc-type separating element is fixed in a liquid-tighten manner such that above that disc-type separating element a second working chamber containing a damping liquid is defined, which is activated when the bearing is unloaded, while below the disc-type separating element a first working chamber is defined, from which the hydraulic liquid is pressed back to the second working chamber when the bearing is compressed by the load to be supported. Two entirely hydraulically independent throttling channels are formed in the disc-type separating element, which throttling channels can be closed by back valves, whose working direction is oppositely directed. Thus each of the two independent channels is passed by the pressurized damping liquid in one flow direction only.
