The hydraulically damping bearing with damping in both the axial direction and the radial direction is further improved to the effect that damping or stiffness that can be switched off or on depending on the operating state is also made possible. The hydraulically damping bush bearing () chambers () of the chamber pairs () can be connected via a closable chamber wall opening ().
