    Abstract: A filter assembly includes a housing within which is disposed a filter element. Inlet means direct fluid to the filter, through which such fluid normally flows. The fluid then normally flows through outlet means defined by the housing. The fluid flowing through the inlet means is in communication with a valve including a valving element movable toward the filter element to allow fluid to flow from the inlet means to the outlet means, bypassing the filter element. A helical spring is disposed between the valving element and filter element to bias the valving element in a position so that the fluid is normally directed through the filter element. An increase of the fluid pressure in the filter element moves the valve element toward the filter element against the resilience of the spring, so that the fluid bypasses the filter element.

    Abstract translation: 过滤器组件包括其中设置有过滤元件的壳体。 入口意味着将流体直接流到过滤器,这种流体通过该过滤器正常流动。 然后,流体通常流过由壳体限定的出口装置。 流过入口装置的流体与包括可朝向过滤器元件移动的阀元件的阀连通,以允许流体从入口装置流到出口装置,从而绕过滤器元件。 螺旋弹簧设置在阀元件和过滤器元件之间,以将阀元件偏置在使得流体通常通过过滤元件的位置。 过滤元件中的流体压力的增加使得阀元件抵抗弹簧的弹性使过滤元件朝向过滤器元件移动,使得流体绕过过滤元件。
