Abstract: A spin-on filter assembly is comprised of a plastic can and a plastic base wherein the plastic base is threaded into the can and secured in place by a rib on the base which seats within a V-shaped slot in the can. In order to have the base separable from the can so the filter may be rebuilt upon removing and replacing the filter element containing the filter media, the rib on the base has both a leading and trailing frustoconical surface. The trailing frustoconical surface on the base enables the base to cam the open end of the housing apart when the base is unscrewed from the can so as to allow the base to be separable from the can. In an alternative configuration, the base has a rib with a flat trailing surface that extends perpendicular to the base. Consequently, there is no base surface provided for caming the open end of the can apart by engaging complimentary frustoconical portion of the groove in the can.

Abstract translation: 旋转式过滤器组件包括塑料罐和塑料底座，其中塑料底座螺纹连接到罐中，并通过底座上的肋固定在适当的位置，该肋位于罐中的V形槽内。 为了使基座与罐分离，因此在移除和更换含有过滤介质的过滤元件时可以重建过滤器，底座上的肋具有前后的截头圆锥形表面。 底座上的后截头圆锥形表面使基座能够在基座从罐上拧下时将壳体的开口端分开，以便允许基座与罐体分离。 在另一种配置中，底座具有一个具有垂直于底座延伸的平坦后表面的肋。 因此，没有设置用于通过在槽中接合凹槽的互补的截头圆锥形部分来使罐的开口端分开的基座表面。

Abstract: A filter for filtering a fluid, such as lubricating oil for an engine, has a full flow filter element and a bypass filter element stacked on the full flow filter element. A flow-deflecting element is disposed between the full flow filter element and bypass filter element to provide a spinning motion to oil flowing from the bypass element as that oil joins oil which is passed through the full flow filter element. The spinning motion of the oil from the bypass filter element encourages mixing of the oil from the bypass filter element with the oil filtered by the full filter element. During operation of the engine this arrangement tends to provide cleaner lubricating oil and therefore reduces engine wear while increasing the time interval between scheduled maintenance.

Abstract translation: 用于过滤流体的过滤器，例如用于发动机的润滑油，具有堆积在全流过滤元件上的全流过滤元件和旁路过滤元件。 在全流量过滤元件和旁路过滤器元件之间设置有流动偏转元件，以便当油接合通过全流过滤元件的油时，为从旁路元件流出的油提供旋转运动。 来自旁路过滤器元件的油的旋转运动促使来自旁路过滤元件的油与由全过滤元件过滤的油混合。 在发动机操作期间，该装置倾向于提供更清洁的润滑油，因此减少发动机磨损，同时增加了定期维护之间的时间间隔。
