    • A filter element (16) includes a ring of filtration media (54) circumscribing a central axis, and first and second end caps (60, 62). The first end cap (60) includes i) an annular body portion (66) defining a central opening (68) around the central axis, sealingly bonded to the first end of the media ring (54), ii) an annular sealing ring (80) having an annular, peripheral resilient sealing portion (82); and iii) axial support stanchions (98) around the periphery of the body portion (66). The stanchions (98) support the sealing ring (80) at a location spaced apart from the body portion (66), and define radial flow openings (92) between adjacent stanchions (90). One or more non-radial flow members (94a, 94b) extend from each stanchion (90) along the outer surface (72) of the annular body portion (66) to direct flow in a spiral or helical manner, where the flow then passes through the flow openings (92) and downwardly along the outer surface of the media (54) in a swirling manner.
    • 过滤元件(16)包括围绕中心轴线的过滤介质(54)环和第一和第二端盖(60,62)。 第一端盖(60)包括i)围绕中心轴限定中心开口(68)的环形主体部分(66),密封地结合到介质环(54)的第一端,ii)环形密封环 80)具有环形的外围弹性密封部分(82); 以及iii)围绕主体部分(66)的周边的轴向支撑支柱(98)。 支柱(98)在与主体部分(66)间隔开的位置处支撑密封环(80),并且在相邻支柱(90)之间限定径向流动开口(92)。 一个或多个非径向流动构件(94a,94b)沿着环形主体部分(66)的外表面(72)从每个支柱(90)延伸,以螺旋或螺旋方式引导流动, 通过流动开口(92)并且以旋转的方式沿着介质(54)的外表面向下。

    • A fluid filter apparatus includes a first surrounding sidewall having inlet and outlet apertures, with first and second end portions, a cover attached to the second end portion and a domed end attached to the first end portion. Also included is a second surrounding sidewall with primary and secondary end portions, being co-axially disposed within the first surrounding sidewall, with a first environment interior disposed therebetween, a second environmental interior disposed within the second surrounding sidewall, and a third environmental interior disposed within said first surrounding sidewall. Further included is a primary strainer disposed between the first and second environments, a vane forming a helical channel within the first environmental adding a centrifugal velocity to the fluid to separate heavier fluids and particulates. Also, a secondary strainer is between the second and third environments, and a filter media is in a third environment.
    • 流体过滤装置包括具有入口孔和出口孔的第一环绕侧壁,其具有第一和第二端部,附接到第二端部的盖和附接到第一端部的圆顶端。 还包括具有第一和第二端部的第二环绕侧壁,共同地设置在第一环绕侧壁内,其间设置有第一环境内部,设置在第二周围侧壁内的第二环境内部和设置在第二环境内部的第三环境内部 在所述第一周围侧壁内。 进一步包括设置在第一和第二环境之间的主过滤器,叶片在第一环境内形成螺旋通道,向流体添加离心速度以分离较重的流体和微粒。 另外,二次过滤器在第二和第三环境之间,并且过滤介质处于第三环境中。
