Abstract

A filter device for a motor vehicle has a filter element with a porous ceramic support body provided with one or more passages for receiving a liquid to be filtered and filter membranes formed on inner walls of the passages. The liquid to be filtered passes through the filter membranes into the support body and exits from the support body through a circumferential surface of the support body. At least one compensation element is arranged at an end face of the support body. The compensation element is elastically deformable for providing an additional liquid volume that is generated when the liquid expands due to freezing.
