    摘要： A filter element has a filter structure and first and second end caps attached to the opposite ends of the filter structure. The filter structure includes an outer filter pack, an inner filter pack, and a helical support positioned between the outer and inner filter packs. The helical support may have flow channels and support ridges on the inner surface and the outer surface of the helical support. Unfiltered fluid may be directed outside-in through the outer filter pack and inside-out through the inner filter pack, the support ridges of the helical support supporting the outer and inner filter packs against the pinching forces associated with the pressure drops across the outer and inner filter packs. Filtrate may be directed axially along the flow channels of the helical support and discharged from the filter element.

    摘要翻译： 过滤元件具有过滤器结构，并且附接到过滤器结构的相对端的第一和第二端盖。 过滤器结构包括外部过滤器组件，内部过滤器组件和定位在外部过滤器组件和内部过滤器组件之间的螺旋式支撑件。 螺旋形支撑件可以在螺旋形支撑件的内表面和外表面上具有流动通道和支撑脊。 未过滤的流体可以通过外部过滤器组件外部引导并且通过内部过滤器组件向内推出，螺旋形支撑件的支撑脊抵靠与跨越外部过滤器组件的压降相关联的夹紧力来支撑外部过滤器组件和内部过滤器组件 内部过滤器包装。 滤液可以沿螺旋形支撑件的流动通道轴向引导并从过滤元件排出。

    摘要： A filter assembly includes a housing and a first filter, a second filter, and a heat exchanger all positioned in the housing. The filter assembly also includes a first inlet and a first outlet and defines a first liquid flow path. The first liquid flow path may extend within the housing between the first inlet and the first outlet through the first filter and along a first side of the heat exchanger. The filter assembly further includes a second inlet and a second outlet and defines a second liquid flow path. The second liquid flow path may extend within the housing between the second inlet and the second outlet through the second filter and along a second side of the heat exchanger.
