Abstract
In order to provide an indicator (100) for compressed air bottles (10;31;50) or such for indicating the falling below a certain level of a defined pressure in the compressed air bottle (10;31;50), which ensures that it becomes discernible in the simplest manner whether a compressed air bottle possesses the requisite pressure and which prevents that, by the measuring of the pressure, an error source of pressure drops is produced, it is proposed that at least a certain portion (23;36;52) of the wall of the compressed air bottle (10;31;50) is constructed in such a way that the same is flexible so that this wall portion, at different pressures, is subject to certain different deformations.
