摘要： A fluid filter arrangement has a housing, a filter cartridge oriented within the housing, and a projection arrangement. The projection arrangement is oriented to space the filter cartridge from a wall of the housing in order to provide a fluid flow path between the filter cartridge and the housing wall. In some arrangements, the projection arrangement is part of an end cap. Embodiments of the projections include axial extensions, radial extensions, and angled extensions including both radial and axial components. Systems of use, methods of filtering, methods of making, and methods of servicing include arrangements of these types.

摘要： A fluid filter assembly includes a housing, a service cover, a center tube removably secured to the service cover, a filter cartridge removably sealed and circumscribing the center tube, and a seal arrangement. The seal arrangement is between the center tube and portions of the housing to close a drainage channel to the flow of clean fluid flow therethrough, when the fluid filter assembly is operating to filter. During normal operation, the fluid filter assembly operates to allow fluid to flow into the housing through an inlet channel, through the filter cartridge, through openings in the center tube, and out of the housing through the outlet channel. Methods for servicing include removing a service cover from a housing to remove, together with the service cover, a center tube, and open a drainage flow passageway from the housing. Next, a filter cartridge is removed from the center tube, and a new filter cartridge is operably mounted on the center tube. Next, the service cover with the center tube having the new filter cartridge is operably mounted in the housing to close the drainage flow passageway. Methods of filtering will direct fluid to be filtered into a housing having a removable and replaceable filter cartridge; then direct the fluid through a tubular region of filter media in the cartridge; then through fluid openings in a center tube; and into a clean fluid flow passageway. Example methods include preventing fluid to bypass the filter media by removably sealing the filter cartridge to the center tube. Example methods will also include preventing fluid from flowing into a drainage passageway by removably sealing the center tube to other portions of the filter housing. Systems utilize filter assemblies as characterized herein include fuel systems, lube systems, and hydraulic systems.
摘要翻译：流体过滤器组件包括壳体，维护盖，可拆卸地固定到维修盖的中心管，可拆卸地密封并围绕中心管的过滤器滤芯以及密封装置。当流体过滤器组件操作以过滤时，密封装置位于中心管和壳体的部分之间以封闭通向其中的清洁流体流动的流动的排水通道。在正常操作期间，流体过滤器组件操作以允许流体通过入口通道，通过过滤器滤芯，通过中心管中的开口流入壳体，并通过出口通道流出壳体。维修方法包括从外壳移除服务盖以与服务盖一起移除中心管，并从壳体打开排水流动通道。接下来，从中心管移除过滤器滤芯，并且将新的滤筒可操作地安装在中心管上。接下来，具有新的过滤器滤芯的具有中心管的维护盖可操作地安装在壳体中以关闭排水流动通道。过滤方法将将要过滤的流体引导到具有可移除和可更换过滤器滤芯的壳体中; 然后将流体引导通过滤筒中的过滤介质的管状区域; 然后通过中心管中的流体开口; 并进入清洁的流体流动通道。示例性方法包括通过将滤筒可拆卸地密封到中心管来防止流体绕过过滤介质。示例性方法还将包括通过将中心管可移除地密封到过滤器壳体的其它部分来防止流体流入排水通道。系统利用如本文特征的过滤器组件包括燃料系统，润滑系统和液压系统。

摘要： A fluid filter arrangement includes a housing defining a slot arrangement. A filter cartridge is oriented within the housing. A projection arrangement engages the slot arrangement in the housing and spaces the filter cartridge from a wall of the housing to define a fluid flow path between the cartridge and the housing wall. A filter cartridge includes a tubular construction of filter media and a projection arrangement. A filter assembly includes the filter arrangement connected to a filter head. Preferably, the filter cartridge and filter head are made of plastic. Methods of assembling a filter includes inserting a filter cartridge and projection arrangement into an open end of a housing, engaging projections against through-slots defined by the housing to secure the filter cartridge in the housing. In some arrangements, a filter housing includes a plastic wall having an interior side with a support structure in the form of ribs extending from the interior side of the housing. In some arrangements, the plastic filter head is modular and may include male threads molded as part of the filter head.
