尤其是用于液压过滤器的过滤材料
摘要：
本发明涉及一种尤其是用于液压过滤器的过滤材料，该过滤材料具有至少一个过滤层(18、20、22、24)，该过滤层的各个单独的过滤褶皱(12)分别由一对过滤褶皱半部(13)组成，该过滤材料包括具有经纱(34)和纬纱(36)的第一结构(32)并且包括具有可预先设定的过滤特性的至少另一个第二结构(20、22)，其特征在于，各结构被如此构造和互相处于作用连接中，即：尤其是通过第一结构(32)的经纱(34)和纬纱(36)的布置结构和几何结构在过滤层(18、20、22、24)内构成至少一个通道引导部(40)，该通道引导部在基本上整个褶皱高度上能够实现相应的过滤褶皱半部(13)的不受干扰的穿流。
摘要（英）：

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 fold 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 (18, 20, 22, 24) in particular as a result of the arrangement and geometry of the warp threads (34) and weft 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.
