    • The present invention relates to a filter for liquid filtration, the construction of the filter ensure increased filtration capacity by using up the filtration medium rather that clogging up. The filter comprises layers of filtration medium (2) and optionally also layers of spacer medium (1). Liquid to be filtered can through bypass spaces circumvent a number of layers of filtration and/or spacer medium and is by at least one sealing (3) directed through the filtering area of filtration medium. End caps (5) with perforations (6) allow the liquid to be distributed within the bypass space between the edges of the layers of filtration medium and spacer medium. Rolled filters with a central core (4) to drain off the filtered liquid can be constructed in large dimensions. Also disclosed is a method making the filter. The filters are suitable for many purposes, especially for filtering liquid with oil.
    • 本发明涉及用于液体过滤的过滤器,过滤器的结构通过使用过滤介质而不是堵塞来确保增加的过滤能力。 过滤器包括过滤介质层(2)和任选地还有隔离介质层(1)。 待过滤的液体可以通过旁路空间绕过若干层过滤和/或间隔介质,并且通过至少一个引导通过过滤介质过滤区的密封件(3)。 具有穿孔(6)的端盖(5)允许液体分布在过滤介质和间隔介质层的边缘之间的旁路空间内。 具有中心芯(4)的带过滤器以排出过滤液体可以在大尺寸上构造。 还公开了制造过滤器的方法。 过滤器适用于许多用途,特别适用于用油过滤液体。
