摘要： An oil filter assembly includes a pressure relief valve adaptable to wide variety of environments while maintaining ease of assembly and manufacture. The pressure relief valve of this invention also occupies a minimal amount of space within the filter assembly as compared to conventional valve arrangements. In the preferred embodiment, the three-piece filter system comprises a base, a deep pocket filtering media, and a housing shell. The unitary filtering media and cap member are formed as a replaceable component that seats into the housing shell without a center tube or other outside support. When the housing shell is threaded onto the base, the cap member is sandwiched between a ledge on the shell and a seal on the base. The pressure relief valve allows fluid to continue to flow in the event the filter element becomes clogged whereby the valve provides ease of assembly, reduced cost, and reduced valve size.

摘要： A three-piece filter system comprises a base, a deep pocket filtering media, and a housing shell. The base is adapted to be fitted/threaded onto an engine block, with a sealing surface to provide a seal with the engine block. The filtering media and cap member is placed pleated-media end down into the housing shell. The filtering media self centers and the housing shell with the filtering media attached is attached to the base. The unitary filtering media and cap member are formed as a replaceable component that seats into the housing shell without a center tube or other outside support. When the housing shell is threaded onto the base, the cap member is sandwiched between a ledge on the shell and a seal on the base. The filter media itself is a solid block and has no center tube. The filter media is a solid pleated pocket design affixed to the cap member. In the preferred design, the filter element is square rather than round to increase surface area. The structure of the filter media eliminates the center tube and compression spring and bottom plate typically used inside the shell of a spin-on filter assembly; thus, the number of parts is reduced and assembly is simplified.
摘要翻译：三件式过滤器系统包括底座，深口袋过滤介质和壳体外壳。底座适于安装/螺纹连接到发动机缸体上，并具有密封表面，以提供与发动机缸体的密封。将过滤介质和盖构件放置成褶状介质端向下进入壳体壳体。过滤介质自身中心和附有过滤介质的外壳与底座相连。单一的过滤介质和盖构件形成为可替换的部件，其可以在没有中心管或其它外部支撑件的情况下安置在壳体壳体中。当壳体外壳被拧到基座上时，盖件被夹在外壳上的凸缘和底座上的密封件之间。过滤介质本身是固体块，没有中心管。过滤介质是固定在盖构件上的固体打褶袋设计。在优选的设计中，过滤元件是正方形而不是圆形以增加表面积。过滤介质的结构消除了中心管和压缩弹簧和底板，通常在旋转过滤器组件的外壳内使用; 因此，部件的数量减少并且组装被简化。

摘要： A central support for a liquid filter is described. The support has a truss element disposable centrally in the liquid filter to provide a crush-resistant structure supporting a filter media of the liquid filter, elongated straight members of the truss element, connected at joints to form a coplanar cross section, and longitudinal members of the truss element, connecting the coplanar cross section and additional coplanar cross sections in a column-like configuration. The contact surfaces of the truss element for interfacing with the filter media are adapted to spread forces on the filter media over a desired surface area.

摘要： A fluid filter is described, which includes a housing having a first end portion defining fluid inlet and fluid outlet areas, a filter media disposed in the housing, having inlet surfaces communicating with the fluid inlet and outlet surfaces communicating with the fluid outlet, and a relief valve assembly for selectively opening a filter bypass connecting the fluid inlet and the fluid outlet. The relief valve assembly has a media plug for anchoring it in the filter media, the media plug having a bypass aperture connecting to the fluid outlet, and a valve element secured to the media plug. The valve element has a valving portion cooperating with the bypass aperture in the media plug for resiliently closing the bypass aperture when an inlet fluid pressure is below a threshold pressure, and for opening the bypass aperture when the inlet fluid pressure is above the threshold pressure.
