Abstract

A hydraulically damped bearing having a first anchoring member (2) and a second anchoring member (3) that are arranged in a movable fashion to one another, having a spring element (6) operating between the first and second anchoring members (2, 3), and having an operating chamber (10) filled with a damping fluid and a compensation chamber (11) separate from the operating chamber (10) and connected to it via a channel (14) that is defined by the channel walls and that allows the fluid to pass through. The volume of the operating chamber (10) changes due to the relative movement of the first and second anchoring members (2, 3), such that the damping fluid is moved in the channel (14) between the compensation chamber (11) and the operating chamber (10). The operating chamber (10) and the compensation chamber (11) are separated by a separating wall (12) that is impacted on both sides by the damping fluid. This separating wall (12) is held in position at the second anchoring member (3) by a separating object (13), where the separating object (13) includes at least a first and a second separating object element (31, 32) which are adjacent in an axial bearing direction. The separating obj…
