Abstract

A hydraulically-damping engine bearing includes a restrictedly deflectable diaphragm separating first and second fluid-filled primary chambers that are bordered at least partially by elastic walls. At least one channel is connected between the first and second primary chambers. An arrangement is connected for adjusting a characteristic of the bearing. The arrangement includes an auxiliary suspension spring that, with the wall of one of the chambers, forms an auxiliary chamber, whereby one of the primary chambers is connectable to the auxiliary chamber via a controllable flow connection.
