1. A hydraulic accumulator, having a separating element which is arranged in an accumulator housing and separates two fluid chambers from one another in a fluid-tight manner, wherein a fluid port is fluidically connected to one of the fluid chambers, wherein the fluid port has a magnetic-field-generating device which is received in a fixed position in the fluid port and separates magnetisable particles out of the fluid passing through the fluid port so as to purify said fluid, and wherein
the magnetic-field-generating device comprises a ring, which is received in an associated wall receptacle in the fluid port and held in position by a fixing sleeve.
