Abstract
A hydraulically damping engine bearing having fluid-filled chambers bordered at least partially by elastic walls, a limitedly deflectable diaphragm separating the chambers, and at least one channel connecting the chambers. A bearing spring rate characteristic is adjustable by an arrangement that includes an additional suspension spring arranged outside of one of the chambers. An intermediate space is bordered by the suspension spring together with an outer wall of one of the chambers. A valve, in communication with the intermediate space, enables the space to be aerated and de-aerated.
