Abstract: A two-chamber step bearing with hydraulic damping especially for mounting engines of motor vehicles is presented. It has at least one fluid-filled working chamber and at least one compensating chamber connected to same by a nozzle channel of variable cross section. The cross section of the nozzle channel is changed by means of a first motor-powered actuating drive. The working chamber is provided with a buckling spring, which is integrated in its walls and whose stiffness can be changed by means of a second motor-powered actuating drive. The second motor-powered actuating drive is independent from the first actuating drive. Due to the described design embodiment the two-chamber step bearing can be continuously adapted during the operation of the two-chamber step bearing to both the damping of low-frequency vibrations of large amplitude and the damping of high-frequency vibrations of small amplitude. The bearing is an especially compact and inexpensive design.

The housing includes rubber-elastic inner and outer walls of different degrees of hardness which are fastened to metallic support members. One of the supports is connected with the foundation and the other with the part (engine) to be supported. One chamber surrounds the other chamber circularly and a passage interconnects the chambers. The walls defining the chambers are incorporated in a housing connected to a support member. The elements comprises a rubber-elastic material and are formed in one piece and are firmly connected with the one supporting member, as well as with a support ring, which is advantageously connected with the other supporting member by mechanical means.

The nozzle channel is defined between profiled parts overlapping one another which are two rigid components of a housing that are adjustable to one another. The channel flow resistance is adjustable by means of a screw-driven regulating unit. The two components forming the nozzle channel there between are adjustable axially relative to one another in the direction of the vertical axis of the mount. One of these components is thread onto a spindle that can rotate freely in the housing. An operating member for rotating the spindle extends out of the housing, and can be screwed on it coaxially with the vertical axis.

Abstract: A hydraulic vibration damper is intended for resilient bearings in motor vehicles and comprises in a housing an inner space which is divided by a partition into a working space above and a lower equalization space, with the two spaces being connected to each other by flow apertures in the partition and their volumes being variable. The partition encloses a horizontal flow channel communicating with the working space and the equalizing space, respectively, through connecting holes which are offset relative to each other. In addition, valve apertures with closing bodies are provided in the partition, which close automatically under increased pressure in the working space.

Abstract: A resilient bearing includes a cushioning member comprising an inner part, an annular element of a resilient material, and an outer part or shell, and a hydraulic damper having an inner space filled with a liquid and being divided by a partition into a working space and an equalizing space. The partition is provided with throttling passages for the liquid flowing therethrough, and the volumes of the separated spaces are variable. The hydraulic damper is accommodated in a housing which is independent of the cushioning member, and comprises a piston which is movable up and down in the working space, thereby varying the volume of the space, and is connected, directly or indirectly, to the inner part of the cushioning member.
