Abstract

A device (1) adjusts a media pressure relative to an ambient pressure defined by a depth-dependent sea water pressure during use of the device (1). The sea water pressure acts on a compensator device (35) that permits a reversible change in length or elongation. At least two compensator elements (41) of the compensator device (35) are provided in series in the direction of the change in length or elongation.
