In a liquid damper for reducing vertical and/or horizontal vibrations in a building or machine structure, having at least two chambers (1, 2) partly filled with liquid (3), which communicate with one another at their lower ends, whereby at least one chamber (1) is sealed off in airtight manner at its upper end, so that a sealed air space (V0) is formed above the liquid (3), and at least one other chamber (2) is at least partly open at its upper end, the sealed air space (V0) is divided into at least two partial air spaces (V01 to V0n), whereby one partial air space (VN) lies directly above the liquid (3), and one or more partial air spaces (V02 to V0n) are connected with the partial air space (V01) that lies directly above the liquid (3), or with the adjacent partial air space (V02 to V0n), in each instance, by way of openings (7), whereby these openings (7) can be closed off, to form a seal, independent of one another.
