摘要： The replaceable, outside-in flow filter element with integral annular trap provides a simple, efficient, tubular filter element that combines the advantages of inside out-flow and outside-in flow filters. The element includes end caps with pleated filter media extending there between. A solid tube is secured between the end caps in a position spaced radially outward from the media. The annular space between the media and the tube forms an integral, lateral, outer trap for containing filtered out particulate matter. The trap allows the particulate to be removed with the used filter element during conventional replacement. The inlet end cap includes openings spaced from an end of the filter media whereby a portion of the openings overlap the media in plan view such that inflow through this overlapping portion of the openings will flow radial outward in the space between the openings and the filter media to the annular space.
摘要翻译：具有集成环形陷阱的可更换的外部流入式过滤器元件提供了一种简单，高效的管状过滤器元件，其结合了内部流出和外部流入过滤器的优点。该元件包括在其间延伸的褶皱过滤介质的端盖。固体管固定在端盖之间的距离介质径向向外的位置。介质和管之间的环形空间形成一个整体的，侧向的外部的收集器，用于容纳滤出的颗粒物质。捕集器允许在常规更换期间用所使用的过滤元件去除颗粒。入口端盖包括与过滤介质的端部间隔开的开口，由此一部分开口在平面图中与介质重叠，使得通过该开口的该重叠部分的流入将在开口和过滤介质之间的空间内径向向外流动到环形空间。

摘要： A top or bottom mounted, in-line, in-tank return line filter element is mounted in a hydraulic reservoir. The reservoir includes a holding tank, at least one outlet extending from and one return line extending to the reservoir, an in-tank return line within the reservoir and extending to one return line, and an in-tank return line filter element mounted within the in-tank return line. The in-tank return line filter element includes an end cap, a filter media and a by-pass valve coupled thereto. The end cap includes a central fluid opening, a mounting surface for the filter media, and a peripheral attaching mechanism for attaching the filter element to the in-tank return line to form a filter assembly. The mounting surface is positioned between the central opening and the attaching mechanism such that an in-line, in-tank filter element is provided.

摘要： A fluid filter element (10) comprises a pleated filter media (34) having spaced apart pleats (40) and an external filter media surface (38) comprising the external peaks of the pleats (40) and a flexible foam filter media sleeve (42) in contact with and extending between the pleats of the peaks of the external filter media surface (38). The filter media sleeve (42) maintains the spacing between the external peaks of the pleats (40) of the pleated filter media (34). The pleated filter media (34) is for fluid applications and includes fragile material media layers (74, 76) between wire meshes (70, 80).
