Abstract:
A device (1) for adjusting a media pressure relative to an ambient pressure which is defined by a depth-dependent sea water pressure during use of the device (1), wherein the sea water pressure acts on a compensator device (35) which permits a reversible change in length or elongation, characterized in that 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.
