Abstract: A filter element for filtering a fluid is provided with a filter bellows made of a filter medium folded along fold edges in a zigzag shape to form folds, wherein the folds extend between oppositely positioned end face edges of the filter bellows. The filter bellows defines a raw side and a clean side of the filter element, wherein a fluid to be filtered flows from the raw side to the clean side. The filter medium has faces that are flowed through by the fluid to be filtered. The filter medium is provided at least on one of the faces that are flowed through with beads extending transversely to the fold edges. In a proper operating state of the filter bellows, the beads effect a flow of at least a portion of the fluid to be filtered in a direction perpendicular to the fold edges.
Abstract translation: 用于过滤流体的过滤元件设置有过滤器波纹管，该过滤器波纹管由以Z字形折叠的折叠边缘折叠的过滤介质形成，其中折叠在过滤器波纹管的相对定位的端面边缘之间延伸。 过滤器波纹管限定过滤元件的原料侧和干净的一侧，其中待过滤的流体从原料侧流向清洁侧。 过滤介质具有被待过滤流体流过的面。 所述过滤介质设置在至少一个所述面中，所述表面通过横向于所述折叠边缘延伸的珠流动。 在过滤器波纹管的适当操作状态下，珠沿着与折叠边缘垂直的方向影响待过滤流体的至少一部分的流动。
