A filter arrangement for liquids has a filter housing and a functional carrier arranged inside the filter housing. A cylindrical filter element is inserted axially into the filter housing and defines an unfiltered side and a filtered side inside the filter housing. A non-return diaphragm is secured within the filter housing, wherein the non-return diaphragm is arranged on the functional carrier so as to effect an axial and/or radial sealing action of the unfiltered side relative to the filtered side of the filter arrangement.

Liquid filtering device

A filter element () suitable for installation in a liquid filter for cleaning a freeze-endangered liquid; the liquid filter having a housing (), composed of a housing pot (), a housing cover (), and a filter element () situated in the housing pot (), with the housing cover () screwed onto the housing pot () in a sealed manner. The filter element () has a first end disk (); a second end disk (), and a filter medium () interposed between the end disks (). The end disks () are mutually connected by a supporting element (), which prevents radial relative movements between the end disks (). In the axial direction, the supporting element () has snap hooks () which connect the first end disk () undetachably to the second end disk (). As a result of this connection, the second end disk () can be reliably removed from the housing pot () by pulling on the first end disk ().

Filter element and liquid filter for freeze-endangered liquids and method for producing such a filter element

An apparatus for filtering a liquid, with a housing, a liquid inlet arranged in the housing, a liquid outlet arranged in the housing, a filter for removing particles from a liquid stream arranged between the liquid inlet and the liquid outlet, and at least one additive for functionally altering the liquid properties arranged in the apparatus, in which the additive is arranged in the interior volume of the apparatus and is shaped in a colloidally disperse, dimensionally stable, elastic form corresponding to at least one geometric space defined by an interior structure of the apparatus or of the filter for removing the particles.
