FILTER MATERIAL, IN PARTICULAR FOR HYDRAULIC FILTERS

摘要

A filter material, in particular for hydraulic filters, comprises at least one filter layer (18, 20, 22, 24), each individual filter fold (12) thereof being composed of a pair of filter bid halves (13), consists of a first structure (32) having warp threads (34) and weft threads (36), and of at least one further second structure (20, 22) with a predeterminable filtering characteristic, and is characterized in that the structures are designed such and are operatively connected to one another such that at least one channel guide (40) is formed in the filter layer (15, 20, 22, 24) in particular as a result of the arrangement and geometry of the warp threads (34) and well threads (36) of the first structure (32), said channel guide allowing an undisturbed flow through the respective filter fold half (13) over substantially the entire fold height.

1. A filter material, in particular provided for hydraulic filters, having at least one filter layer (18, 20, 22, 24), the individual filter folds (12) of which are each composed of a pair of filter fold halves (13), comprising a first structure (32) having warp threads (34) and weft threads (36), and comprising at least one further, second structure (20, 22) having a predefinable filtration characteristic, characterized in that the structures are designed such and are operatively connected to one another such that, in particular by means of the configuration and geometry of the warp threads (34) and weft threads (36) of the first structure (32), at least one channel guide (40) is formed inside the filter layer (18, 20, 22, 24), which channel guide enables an unimpeded flow through the respective filter fold half (13) over substantially the entire fold height.
