Abstract

2. Bei einem Druckspeicher mit einer innerhalb eines Speichergehäuses 1 längs verfahrbaren, aus Hauptkolben 17 und relativ zu diesem bewegbarem Hilfskolben 19 gebildeten Kolbenanordnung, die eine Fluidseite 25 des Speichers von seiner Gasseite 23 über eine Dichteinrichtung abdichtend trennt, welch letztere ein Trennmittel 43 mit Tiefenfiltrationseigenschaft, weitere Dichtelemente 47 sowie eine an die Innenwand des Speichergehäuses 1 angrenzende Kammer 35, 39 für ein strömungsfähiges Dichtmedium aufweist, das durch den Hilfskolben 19 vorspannbar ist, der für eine das Volumen der Kammer 35, 39 verkleinernde Relativbewegung mit dem Druck der Gasseite 23 und der Kraft eines Kraftspeichers 33 beaufschlagt ist, ist der Hilfskolben 19 vollständig integriert in einer zur Gasseite 23 offenen Führung 21 des Hauptkolbens 17 geführt, in welchem mittels des Hilfskolbens 19 ein Raum 35 einschließbar ist, der Teil der das strömungsfähige Dichtmedium aufnehmenden Kammer 35, 39 bildet.
