The invention relates to a filter device () for filtering liquids, comprising: a filter element () having an interior () for accommodating a liquid, and a compensating element () made of elastically deformable material for accommodating a liquid volume that increases when the liquid freezes. The compensating element () is arranged in the interior (), and a gap (), in particular an annular gap, for accommodating the liquid is formed between the compensating element () and the filter element ().

Filter device for filtering liquids

A filter element for purifying a fluid at risk of freezing such as a urea-water solution for exhaust gas after treatment has an annular filter body and a support body surrounded by the filter body. The support body is made of an elastomer and is able to yield in a radial inward direction to compensate volume expansion when the fluid freezes.
