    Abstract: Liquid filter assemblies, features, components and methods are described. In general, a liquid filter cartridge is provided which includes features that help ensure that when the assembly is serviced, the cartridge positioned within the assembly is a proper one, in proper sealing orientation, for appropriate use. Features that can be used to provide for this include: a seal on the filter cartridge that defines a seal pattern non-orthogonal to a plane perpendicular to a central axis of the filter cartridge; and, a member of a projection/receiver arrangement on the filter cartridge which is orientated to engage a portion of a liquid filter assembly, for example a liquid flow collar, to allow sealing when the cartridge is a properly positioned cartridge and a properly configured cartridge. Assembly features are described. Also, a flexible radial projection arrangement providing snap-fit interaction between a cartridge and housing is provided. Methods of assembly and use as described.

    Abstract translation: 描述了液体过滤器组件，特征，组件和方法。 通常，提供了液体过滤器滤芯，其包括有助于确保当组件被维护时的位置在适当的密封方向上适当的位于组件内的盒的特征。 可用于提供的特征包括：过滤器滤芯上的密封件，其限定与垂直于过滤器滤芯的中心轴线的平面非正交的密封图案; 以及位于过滤器滤芯上的投影/接收器装置的构件，其被定向成接合液体过滤器组件（例如液体流动轴环）的一部分，以在盒是适当定位的盒和适当配置的盒时允许密封 。 描述装配特征。 而且，提供了提供盒和壳体之间的卡扣配合相互作用的柔性径向突出装置。 如上所述的组装和使用方法。

    Abstract: A spin-on filter cartridge includes a housing, a filter element operably oriented in the housing, a baffle plate, and a seal arrangement. The baffle plate is operably oriented over the housing open end and defines a central flow aperture. The baffle plate also defines a continuous groove immediately adjacent to and circumscribing the central flow aperture. The seal arrangement is secured to the baffle plate and spaced from and circumscribing the continuous groove. A filter assembly including the spin-on filter cartridge and a filter head is also disclosed wherein the filter cartridge is removably mountable on the filter head. When the spin-on filter cartridge is oriented on the filter head, a seal member is received within the continuous groove and the seal arrangement forms a seal between and against the baffle plate and the filter head. The seal can be radial or axial or have both axial and radial components.

    Abstract translation: 旋转式滤芯包括壳体，可操作地定向在壳体中的过滤元件，挡板和密封装置。 挡板可操作地定位在壳体开口端上并限定中心流动孔。 挡板还限定了紧邻中心流动孔的连续槽。 密封装置被固定到挡板上，与连续凹槽间隔开并限制。 还公开了一种包括旋转过滤器滤芯和过滤头的过滤器组件，其中过滤器滤芯可拆卸地安装在过滤器头部上。 当旋涂过滤器滤芯定位在过滤器头上时，密封件被容纳在连续槽内，并且密封装置在挡板和过滤头之间形成密封。 密封件可以是径向的或轴向的或具有轴向和径向部件。
