发明名称 LIQUID FILTER ARRANGEMENT AND METHODS
摘要 A filter element includes filter media, first and second end caps, a latch arrangement projecting from the first end cap, a tubular neck extending from the first end cap and a valve head oriented within the first end cap aperture constructed and arranged to move between a position sealing the first end cap aperture and exposing the first end cap aperture. A filter assembly includes a filter element, as characterized herein, and including a filter base and a service cover. A method of servicing includes removing an old filter element, operably mounting a new filter element in a filter base including engaging a valve head against a spring member in the filter base, and operably mounting the service cover over the new filter element and filter base. A method of filtering includes directing liquid into a filter assembly, blocking a first end cap aperture by using a spring member in the filter base to urge the valve head against a rim of a tubular neck extending from the filter element, and directing liquid through the filter media to filter the liquid.
