Abstract (en)
[origin: WO2011079852A1] A hydraulic accumulator, especially a bellows accumulator, wherein the bellows serving as the mobile separating element between the gas side (21) and the fluid side (23) comprises a closing element (35) that closes the interior of the bellows in a fluid-tight manner on the bellows end (31) that can be axially displaced in the accumulator housing (1) during expansion and compression and is immobilized on the other bellows end (29) relative to the accumulator housing (1), is characterized in that a sealing system (37) sealing the interior of the bellows from the accumulator housing (1) on the immobile bellows end comprises, in addition to a first functional area (63) having a sealing effect, a second functional area in the form of an attachment projecting into the interior of the bellows, at least one bulge (73) projecting axially towards the mobile bellows end (31) forming a flexible buffer for the contact of the closing element (35) of the bellows when the latter is completely compressed.
