A storage device for a liquid medium has a housing having an interior provided with at least one partitioning element dividing the interior into a first chamber for receiving the liquid medium and into a second chamber filled at least partially with a gas under pressure. The gas keeps the liquid medium in the first chamber under pressure. The at least one partitioning element is formed at least partially of an expandable bellows fastened pressure-tightly to a lid of the housing.
