Abstract

Bei einem Kolbenspeicher mit einem innerhalb eines Speichergehäuses (1) axial verfahrbaren Trennkolben (13), der eine Fluidseite (15) des Speichers von einer Gasseite (23) trennt und an seinem an der Innenwand des Speichergehäuses (1) geführten Umfang zwei in Axialrichtung zueinander versetzte Abdichtungsbereiche (17, 25) aufweist, weist das Speichergehäuse (1) an einer zwischen den Abdichtungsbereichen (17, 25) gelegenen Stelle eine Entlüftungsmöglichkeit (31) zur Ableitung von die Abdichtungsbereiche (17, 25) überwindenden Leckmedien auf.
