| 摘要 |
The invention relates to a hydraulic accumulator, preferably a membrane accumulator, in particular for damping pulsations in fluid circuits, comprising an accumulator housing (12), with at least one inlet (14) and an outlet (16) for the fluid for damping, whereby a separating element (18), preferably in the form of a membrane, separates a gas reservoir (20) from a fluid chamber (22) within the accumulator housing (12). According to the invention, a hydraulic accumulator with high working capacity of high reliability which little space requirement despite high accumulation capacity for the working gas in the gas reservoir (20) can be achieved, whereby an embodiment has a support device (24) within the accumulator housing (12), running within the gas reservoir (20) or defining the same, forming a possible support for the separating element (18) and the gas reservoir (20) of the accumulator housing (12) is sufficiently large in dimension that the total necessary gas volume is retained within the accumulator housing (12) itself and/or alternatively the membrane is formed from an elastic material, in particular a rubber material and comprises polytetrafluoroethylene or compounds thereof as a gas barrier layer. |
