Abstract
The disclosure relates to a hydraulic accumulator, in particular in the form of a piston-type accumulator, having a separating element which is arranged in an accumulator housing and fluid-tightly separates two fluid chambers, in particular a closed accumulator chamber comprising a working gas and a liquid chamber comprising an operating liquid such as hydraulic oil, from one another, wherein a fluid port is fluidically connected to one of the fluid chambers. The hydraulic accumulator is characterised in that the fluid port has a magnetic-field-generating device which is received in a fixed position in the fluid port and separates magnetizable particles out of the fluid passing through the fluid port, to purify said fluid.
