Patent ID: 8783667

Claim:
An axially damping hydraulic mount comprising: a frustoconical elastomer support spring arranged between a mount core and an upper part of an outer jacket, a working chamber for receiving a fluid damping means and an equalizing chamber enclosed by an elastomer bellow, protected by a lower part of the outer jacket, the equalizing chamber is separated from the working chamber by a separating element including a yielding and non-perforated separating membrane extending transversely with respect to a longitudinal axis, the separating membrane having an upper surface and a lower surface, a plurality of beads disposed on each of the upper surface and the lower surface of the separating membrane, a duct enclosed by at least one duct part is formed on the separating element, with the duct enabling transfer of damping means between the working chamber and the equalizing chamber, and wherein at least one mass element is applied to the at least one duct part including a duct disk cover and a duct cover disk, wherein the at least one duct part is rigidly connected to the at least one mass element, wherein the at least one mass element bears against the plural beads disposed on each of the upper surface and the lower surface of the separating membrane, wherein the liquid in the working chamber does not contact the separating membrane, wherein an outside periphery of the separating membrane is disposed between the duct disk and the duct cover disk.
