  • Patent number: 9212721
    Abstract: A hydromount comprising a carrying mount and a support mount connected to each other by an elastomeric suspension spring. The hydromount includes a working chamber and a compensation chamber that are filled with a fluid and separated by a partition, and connected to each other via a damping channel inserted into the partition. The hydromount includes an absorber channel that is switchable via an actuating device. The absorber channel is inactive in a first switching position of the actuating device and active in a second switching position of the actuating device. The actuating device has an electrically drivable electromagnet and an armature suspended via an elastic membrane so as to allow the armature to vibrate. The membrane is surrounded by a limiting member such that the membrane abuts against the limiting member in the first switching position and is spaced from the limiting member in the second switching position.
