Abstract: An apparatus for damping torsional vibrations in a drivetrain, including a drive device and an output device, which drive device and output device are arranged so as to be rotatable around a common axis, a damping device that connects the drive device and the output device to one another, and a thrust bearing device for axial support of drive device and the output device. The drive device, cover device, and thrust bearing device are arranged such that a partially enclosed spatial region is formed, and at least one damping element of the damping device is arranged in the spatial region. Elements of the drive device, the cover device, the output device and the thrust bearing device are arranged to inhibit liquid entry into the spatial region.
