Embodiment Construction

[0052] figure 1 A filter element is schematically shown, which is used, for example, in a hydraulic filter. Use in hydraulic filters is particularly preferred. The filter element can be used in other filters. It comprises a perforated sleeve or cylindrical support tube 12 through which a plurality of flow openings 13 pass in radial direction. In the circumferential direction, the support tube 12 is surrounded by a multilayer filter bellows 15, which is partly shown in an exploded view for illustration figure 1 shown in . The filter bellows 15 can also be referred to as a corrugated or corrugated flat material. The filter bellows 15 is pleated in a star-shaped fashion with pleats 17 extending parallel to the longitudinal axis of the support tube 12 such that radially outer pleat peaks 18 and radially inner pleat bases 19 follow each other alternately along its circumference.

[0053] The filter bellows 15 comprises in particular three layers of filter material 22 with a fi...

Abstract

The invention relates to a fabric layer, in particular a protective fabric and/or backing fabric, for a corrugated or pleated flat material of a filter element, wherein the flat material comprises a plurality of pleats 17 or corrugations running parallel to one another, which form successive pleat or corrugation peaks 18 and pleat or corrugation troughs 19, which are connected to one another by apleat flank, wherein a fluid can flow through the flat material, wherein the fabric layer comprises a first fabric region, in particular a first fabric strip 10, and at least one second fabric region,in particular a second fabric strip 11, the threads whereof, in particular weft threads, merge into one another, wherein the first fabric region, in particular the first fabric strip, comprises a first type of weave and the second fabric region, in particular the second fabric strip, a second type of weave, which differs from the first type of weave.

Description

technical field [0001] The invention relates to a fabric layer for a corrugated or pleated flat material of a filter element. Such a textile layer is known, for example, from WO 2009 / 026978 A2. The invention also relates to a flat material having such a fabric layer, a filter element, a filter and a method for producing the fabric layer. Background technique [0002] Foreign bodies, such as contamination particles, can be removed from the fluid by means of such a flat material, so that the foreign body content in the fluid can be reduced by flowing through the flat material. To increase the effective area of ​​the flat material, the flat material is corrugated or corrugated. The effective usable area is thus increased without having to increase the outer dimensions of the flat material. This flat material is also called filter bellows. The load on the flat material due to fluid flow through may have the effect that the folds or corrugations on the downstream side of the ...
