Abstract

Separator and hydraulic accumulator having such a separator. A separator, in particular for a hydraulic accumulator, such as a bellows accumulator, which is produced by a 3D printing process, consisting of one single diaphragm, which, when viewed in cross section, is deflected in an arcuate shape to form a multitude of bellows pleats at deflection points, which delimit the bellows pleats on the outside and the inside, and in that, to obtain an isotensoid or essentially isotensoid stress profile in the diaphragm, the notional extensions of the diaphragm surfaces adjacent to each deflection point form an acute angle with each other, at least in an initial state.
