Abstract

Die Erfindung betrifft einen Kolbenspeicher mit einem innerhalb eines Speichergehäuses 10 längsverfahrbaren ersten Trennkolben 12 und einem zweiten Trennkolben 18, die zwei Speicherräume, insbesondere eine Fluidseite 14 von einer Gasseite 16 trennen, wobei ein zwischen den beiden Trennkolben 12, 18 angeordneter Zwischenraum 20 mit einem Dichtmedium befüllt ist. Dadurch daß unter der Krafteinwirkung einer Vorspanneinrichtung 50 die beiden Trennkolben 12, 18 derart aufeinander zu bewegbar sind, daß das Dichtmedium vorgespannt ist, ist ein Kolbenspeicher geschaffen, der auch unter extremen Bedingungen bei langen Einsatzzeiten seine Dichtigkeit behält und sicherstellt, daß in keinem Betriebszustand Gas zur Fluidseite hin entweichen kann.
