Abstract
A pressure store includes a housing () having a first sub-chamber () arranged between the housing () and a flexible separating diaphragm (), a second sub-chamber () arranged between the separating diaphragm () and a supporting body (), and a third sub-chamber () encompassed by the supporting body (). The first sub-chamber () can be filled with a first fluid. The second sub-chamber () and the third sub-chamber () are connected to one another in fluid-conducting fashion and can be filled with a second fluid. The first and the second sub-chambers () vary in respective sizes as a result of movements of the separating diaphragm () as a function of the respective filling state. The first fluid is a storage medium and the second fluid is working medium. The second sub-chamber () is increased in size during the extraction of storage medium from the pressure store and is reduced in size during the filling of the pressure store with storage medium.
