Abstract (en)
[origin: WO2013064233A1] The invention relates to a hydraulic accumulator, comprising an accumulator housing (1), in which a bellows (21) having a selectable number of pleats (23) forms a mobile separation element between the gas side (25) and the fluid side (13), characterized in that a distancing device (33) is provided arranged inside the accumulator housing (1), and is fluidically connected to the inside of the bellows (21) or abuts to the bellows (21), thus forming an additional medium chamber.
