Abstract: A nozzle plate for an axially damping hydraulic mount having a passage disk with a passage for connecting a work chamber and a balance chamber of a hydraulic mount. The passage disk is rotationally fixable at a first angular position in the hydraulic mount. The nozzle plate also has a cover disk with an aperture that is arranged above the passage at a pre-definable angular position. The passage of the passage disk is bound on one side by the cover disk. The aperture forms an inlet opening into the passage or an outlet opening out of the passage for a fluid damping agent. The cover disk is rotationally fixed such that the aperture is at a second angular position selected from a plurality of different angular positions with respect to the passage disk.

Abstract: A hydraulic engine bearing for motor vehicles has a fluid-filled working chamber (4) surrounded by a rubber-elastic circumferential wall (3). A compensating chamber (7) is provided which is in connection with the working chamber (4) via an overflow duct (6) in a baffle plate (5) between the working chamber (4) and the compensating chamber (7). Another compensating chamber (10) is connected to the working chamber (4) via a bypass duct (9). The additional compensating chamber (10) is formed from an elastic bellows (11), which is surrounded on its outside by a fixed wall (12) and wherein an intermediate space (13) is arranged between the bellows (11) and the wall (12). The intermediate space can be filled with a compressible medium, preferably air, and the medium can be emptied by means of a switching device, wherein the switching device is formed from at least one non-return valve (14) and at least one on-off valve (15).
