    • Filter assemblies are disclosed that include a pleated web in which the pleats are connected to each other to provide support for the filter media during use. The interconnected pleats preferably form an array of openings facing the upstream side of the filter assembly when subjected to fluid pressure during use. In addition, the preferred filter media also includes an array of pockets located behind each of the points at which the pleats are connected. By connecting the pleats to form arrays of openings and pockets during use, the filter assemblies provide a structure that deforms in a predetermined, acceptable manner without the need for external support structure to support the pleats.
    • 公开了一种过滤器组件,其包括打褶腹板,其中褶皱彼此连接以在使用期间为过滤介质提供支撑。 当在使用过程中经受流体压力时,互连褶皱优选地形成面向过滤器组件的上游侧的开口阵列。 此外,优选的过滤介质还包括位于褶皱连接的每个点后面的凹穴阵列。 通过在使用期间连接褶皱以形成开口和袋子阵列,过滤器组件提供以预定的可接受的方式变形而不需要外部支撑结构来支撑褶皱的结构。
