    摘要： An improved sealing grommet for a spin-on type fluid filter has an annular flange coupled to an interior wall of the grommet body which sealingly engages filter adapter standpipes of varying diameters. An annular cavity, formed by the interior wall of the grommet body and the annular flange, allows pressurized fluid within the annular cavity to exert forces against the surface of the cavity to thereby enhance the sealing engagement between the filter element, the base plate and the filter adapter standpipe.

    摘要： A flexibly resilient sealing member, incorporating integral pressure relief valves, for use in an oil filter assembly, includes a substantially annular body formed from a flexibly resilient material. The annular body has a central bore formed therein for surrounding an oil filter outlet. The annular body also has an upper surface with a plurality of normally closed slits formed therein, a shoulder portion around its top outer edge for sealing placement inside a cylindrical filter element, and a flow channel formed therethrough for each of the normally closed slits, each of the flow channels extending downwardly from one of the normally closed slits and terminating in an open inlet below the shoulder portion and outside of the central bore. The sealing member according to the present invention may further include an integral pedestal ring attached to the lower surface of the annular body adjacent the annular bore and extending downwardly therefrom, and a transverse flange attached to the outer surface of the annular body below the shoulder portion, and extending outwardly therefrom to limit entry of the sealing member into a filter element. In this embodiment, preferably, each of the flow channels extends from a bottom surface of the annular body above the pedestal ring, through the annular body; and communicates with one of the normally closed slits in the top surface of the annular body. The present invention also encompasses an oil filter assembly incorporating the sealing member thereof.

    摘要翻译： 包括用于油过滤器组件的整体式压力释放阀的柔性弹性密封构件包括由柔性弹性材料形成的大致环形体。 环形体具有形成在其中的中心孔，用于围绕滤油器出口。 环形体还具有形成在其中的多个常闭狭缝的上表面，围绕其顶部外边缘的用于密封放置在圆柱形过滤器元件内的肩部部分，以及为每个常闭狭缝形成的流动通道 的流动通道从常闭狭缝之一向下延伸并终止在肩部下方的开口入口和中心孔的外部。 根据本发明的密封构件还可以包括：一体式基座环，其与环形孔的下表面相邻并且从其向下延伸;以及横向凸缘，其连接到肩部下方的环形体的外表面 并且从其向外延伸以限制密封构件进入过滤元件。 在该实施例中，优选地，每个流动通道从基座环上方的环形体的底表面延伸通过环形体; 并且与环形体的顶表面中的常闭狭缝之一连通。 本发明还包括结合其密封构件的油过滤器组件。
