Embodiment Construction

[0029] figure 1 It represents a rectangular section of filter material 2 , which is designed in planar form and is constructed in multiple layers from filter medium 4 and support structure 6 . The filter medium 4 consists of a plastic fleece in one layer. The support structure 6 comprises filament elements 10 a , 10 b , 10 c , 10 d , 10 e running in the warp direction 8 and further filament elements 14 a , 14 b , 14 c running in the weft direction 12 . The filament elements 10a, 10b, . . . , 14a, 14b, . . . form a regular fabric, wherein the filament elements 10a, 10b, . The interweaving is over and then under the nearest filament element 10a, 10b, . . . , 14a, 14b, . . . Filament elements 10a, 10b, . . . , 14a, 14b, . . . have substantially the same thickness d S 、d K . d K The values ​​of are, for example, 246 microns and 262.4 microns; d S The values ​​of , for example, are 252.6 microns and 242.8 microns. Furthermore, groups of filament elements 10a, 10b, ..., and...

Abstract

The invention relates to a filter material (2) for fluids, in particular hydraulic fluids, comprising a filter medium (4) having at least one layer, and a supporting structure (6) which is partially made of a plastic material and rests flatly in some surface areas on at least one side of the filter medium (4). Said filter material is characterized in that the filter medium (4) and the supporting structure (6) are connected to one another by laminating, covering and / or by a melting process.

Description

technical field [0001] The invention relates to a filter material for fluids, in particular for hydraulic fluids, comprising a filter medium having at least one layer and at least A support structure formed partly of a plastic material, and a method for manufacturing such a filter material. Background technique [0002] Various filter materials are known for producing replaceable filter elements in hydraulic systems, for example consisting of filter nonwovens, preferably in multiple layers, on one or both sides (inflow side and outflow side) Has a supporting structure. The hydraulic fluid to be filtered flows through this filter element, and when it flows from the unfiltered side to the clean side, a considerable pressure difference is generated. In order to be able to withstand this pressure difference and the dynamic flow forces in the unfiltered liquid, the filter material made of the corresponding filter elements has a so-called support structure. Such a support struc...
