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). The non-return valve (14) is arranged in a vent duct as a connection path of the intermediate space (13) to the outside of the fixed wall (12) such that only a flow of the medium present in the intermediate space (13) to the outside of the wall (12) is possible. The on-off valve (15) is arranged at a vent duct (17) as an additional connection path of the intermediate space (13) to the outside of the engine bearing and can close or open the vent duct (17).
