摘要： A filter bag assembly (10) includes an outer bag (20) having an open end (22), a closed end (24) opposite the open end (22), and a longitudinal axis. The open end (22) of the outer bag (20) is sized and shaped for receiving liquid to be filtered. A filter member (42) is loosely mounted in the outer bag (20) and has a pair of opposed open ends (44, 46) and a plurality of longitudinally extending pleats (60). Each of the pleats (60) projects generally outwardly in a radial direction.

摘要： The present invention relates to a novel filter element having a septum with a staged pleating that repeats a pleating sequence having a major (longest) pleat, a minor (shortest) pleat and at least one intermediate pleat therebetween. The intermediate pleat(s) have pleat heights that are evenly distributed within the range of pleat heights bounded by the pleat height of the minor pleat and the pleat height of the major pleat. In two particular embodiments of the invention, the pleat height ratios of the major, intermediate and minor pleats are 3:2:1 and 4:3:2:1. In an filter element, the pleated septum may be held between an inner core and an outer guard. The tip of the major pleat in each pleating sequence may be in contact with the inner core of the filter element. The septum may also include drainage layers on upstream and downstream of the filter material layer.
摘要翻译：本发明涉及一种具有隔膜的新型过滤元件，其具有重复具有主要（最长）褶皱，次要（最短）褶皱和其间的至少一个中间褶皱的褶皱序列的褶皱褶皱。中间褶具有均匀分布在由小褶皱的褶皱高度和主褶皱的褶皱高度限定的褶皱高度的范围内的褶皱高度。在本发明的两个具体实施方案中，主要，中间和次要褶皱的褶皱高度比为3:2:1和4:3:2:1。在过滤元件中，打褶的隔膜可以保持在内芯和外护罩之间。每个打褶顺序中的主褶皱的尖端可以与过滤元件的内芯接触。隔膜还可以包括在过滤材料层的上游和下游的排水层。

摘要： A filter product includes a filtration media combined with a multi-component frame assembly that can effectively support the filtration media in place proximal to its edges and in accordance with its desired orientation and wherein the assembly can be selectively taken apart to provide access to the filtration media by way of a releasable lock connection. Preferably, a snap-fit releasable locking system is incorporated within the frame design. The present invention is particularly applicable to filtration media comprising pleated filtration media. Such support features include rack-like media engagement elements, which elements are advantageously provided so as to preferably engage the filtration media proximal to its side and end edges from above and below to preferably compress and ensure an effective seal and support connection between the frame and the filtration media. Such a construction is further beneficial for supporting filtration media that includes a layer or other loading of particulate matter therein. The media engagement elements are spaced along the side of a support frame and a hold down frame and the side frame elements include sidewalls in combination. The sidewalls are spaced from the media engagement elements so as to support and preferable compress the filtration media inward from its side and end edges to support and effectively contain the filtration media and any particulate material therein.
摘要翻译：过滤产品包括与多组分框架组件相结合的过滤介质，其可以将过滤介质有效地支撑在其边缘附近的适当位置并且根据其期望的取向，并且其中组件可以选择性地拆开以通过可释放的锁定连接提供进入过滤介质。优选地，搭扣配合的可释放锁定系统结合在框架设计内。本发明特别适用于包括打褶过滤介质的过滤介质。这种支撑特征包括机架状媒体接合元件，所述元件有利地设置为优选地接近过滤介质接近其侧面和端部边缘，从上方和下方优选地压缩并确保框架与支架之间的有效密封和支撑连接过滤介质。这样的构造对于支撑包括其中的颗粒物质层或其他负载的过滤介质而言更有利。介质接合元件沿着支撑框架和压制框架的侧面间隔开，并且侧框架元件包括组合的侧壁。侧壁与介质接合元件间隔开，以支撑并优选将过滤介质从其侧边缘和端部边缘向内压缩，以支撑并有效地容纳过滤介质和其中的任何颗粒材料。

摘要： The filter insert disclosed comprises a multiplicity of zig-zag-shaped pleated walls (43, 44) made of a material which is permeable to the fluid to be filtered, the fluid passing through the filter insert from one edge of the zig-zag to the opposite edge. Projecting out from each zig-zag wall (43, 44) towards a neighbouring wall (43, 44) are projections (45) formed by embossing, which extend in the direction of motion of the fluid and, in particular, are longer than they are wide. The projections (45) from neighbouring zig-zag walls (43, 44) abut each other, thus ensuring correct separation and increasing structural strength, and the abutting projections (45) of two zig-zag walls joined by an edge (46) are shaped so that their height increases towards the opposite edge (46) and the edges (46) broaden substantially trapezoidally.
