Abstract
A hydraulically damped bearing having a first anchoring member ( ) and a second anchoring member ( ) that are arranged in a movable fashion to one another, having a spring element ( ) operating between the first and second anchoring members ( ), and having an operating chamber ( ) filled with a damping fluid and a compensation chamber ( ) separate from the operating chamber ( ) and connected to it via a channel ( ) that is defined by the channel walls and that allows the fluid to pass through. The volume of the operating chamber ( ) changes due to the relative movement of the first and second anchoring members ( ), such that the damping fluid is moved in the channel ( ) between the compensation chamber ( ) and the operating chamber ( ). The operating chamber ( ) and the compensation chamber ( ) are separated by a separating wall ( ) that is impacted on both sides by the damping fluid. This separating wall ( ) is held in position at the second anchoring member ( ) by a separating object ( ), where the separating object ( ) includes at least a first and a second separating object element ( ) which are adjacent in an axial bearing direction. The separating object elements ( ) are braced against each other and form a first radial inner section of the channel wall. A housing section ( ) formed onto the second anchoring member ( ) forms a radially outer section ( ) of the channel wall.
