Abstract: A replaceable filter cartridge for use in a fluid filter assembly includes a substantially cylindrical filter element including a pair of oppositely disposed filter element ends. A first endplate is bonded to one of the filter element ends so as to close the end and prevent fluid leakage therethrough. A second endplate is bonded to the opposite filter element end so as to close the opposite end and prevent fluid leakage therethrough. The second endplate includes an outer annular wall which is sized so as to create a noticeable distance of separation between the second endplate outer wall and the outer surface of the filter element and thereby define an annular clearance space therebetween. The outer wall of the second endplate is annular and substantially concentric with the filter element and provides a lip or free edge for the snap-on assembly of a closing lid member. By configuring the lid member with a series of snap-over fingers, it is possible to simply snap the lid onto the second endplate and thereafter use the lid for handling and manipulation of the replaceable filter cartridge.

Abstract translation: 用于流体过滤器组件的可替换的过滤器滤芯包括基本上圆柱形的过滤器元件，其包括一对相对设置的过滤元件端部。 第一端板结合到过滤元件端部之一以闭合端部并防止流体从其中泄漏。 第二端板结合到相对的过滤器元件端部，以便封闭相对端并防止流体从其中泄漏。 第二端板包括外环形壁，其尺寸设计成在第二端板外壁和过滤元件的外表面之间产生明显的间隔距离，从而在其间限定环形间隙空间。 第二端板的外壁是环形的，并且与过滤元件基本上同心，并为闭合盖构件的卡扣组件提供唇缘或自由边缘。 通过使用一系列卡扣式手指构造盖构件，可以简单地将盖子卡到第二端板上，然后使用盖子来处理和操纵可更换的滤筒。
