Abstract
A pressure accumulator has a housing having at least one pressure medium opening, a diaphragm chamber arranged inside the housing and having a side wall which is at least partially deformable, and a pressure medium chamber arranged outside of the diaphragm chamber, the pressure medium chamber at least partially being limited by a partially permeable material which allows an exit of gas from the pressure medium chamber but prevents an exit of a pressure medium from the pressure medium chamber.
