摘要： A filter arrangement for threadably securing to a filter head includes a housing having a surrounding wall defining an interior volume, an open mouth providing access to the interior volume and an end opposite of the open mouth. The surrounding wall has an exterior and an interior. A filter media construction is operably held within the interior volume. A sleeve, distinct from the housing, is secured to the exterior of the surrounding wall adjacent to the housing mouth and extending partially along the surrounding wall. The sleeve has an exterior and an interior. The exterior of the sleeve defines mounting threads constructed and arranged to removably mount with the filter head, when the filter arrangement is secured to the filter head. The interior of the sleeve is against the exterior of the surrounding wall. A first seal member is oriented against the sleeve to create a seal with a filter head, when the filter arrangement is secured to the filter head. A filter assembly includes a filter arrangement and a filter head. The filter arrangement is removably secured to the filter head by a threaded connection between the sleeve and the filter head. A system includes an engine utilizing a liquid and a filter assembly in fluid communication with the engine to filter the liquid. Methods of making filter arrangements include utilizing structures characterized above.

摘要： A filter cartridge includes a key ring with at least first and second protrusions to engage a lock-out assembly in a filter head, permitting the cartridge to connect to the filter head. A filter system includes a filter assembly, including a filter cartridge and a cartridge housing, connected to a filter head, in which the filter head includes an adapter assembly with a lock-out mechanism. The lock-out mechanism is unlocked by a key ring on the filter cartridge. A method of installing a filter assembly includes using protrusions on a key ring on a filter cartridge to unlock an adapter assembly in a filter head to allow for connection between the filter assembly and the filter head.

摘要： A filter cartridge 38 includes a first endcap 41 defining a first open aperture and having at least first and second protrusions extending from a wall along the aperture and into the first open aperture. The first protrusion is spaced from the second protrusion in both a vertical direction and a circumferential direction. The filter cartridge also includes filter media 44 and a second endcap 42 . The filter cartridge is mountable in a filter bowl 36 having an inner liner assembly, and the bowl and the inner liner assembly is connectable to a filter head to form a filter system. The filter system can have any one or combination of the following features: a filter lock-out mechanism to ensure that the filter head and the filter bowl are not connectable unless there is a proper filter cartridge installed therein; an automatic drain mechanism to drain the filter bowl of liquid before the filter cartridge is removed from the bowl; and a cartridge retention mechanism, to ensure that the filter cartridge remains with the filter bowl after the filter bowl has been removed from the filter head. Adaptor rings can be utilized in order to test other types of filter elements in the system, when those other types of filter elements do not have the protrusion arrangement. Assemblies, methods of servicing, methods of installing, methods of use, and methods of retaining can be practiced.

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.

摘要： A fluid filter element for use in fuel filtration systems is disclosed. The filter element comprises, in an example embodiment, top and bottom end caps; filter media extending between the end caps and forming a central volume between the end caps; and an inner liner disposed in the central volume of the filter media between the end caps. A fluid passage is positioned in the inner liner extending between the end caps, the fluid passage being separate and independent of the flow through the filter media. A first seal is affixed to the bottom end cap; and a second seal with a central opening is affixed to the lower end of the inner liner. The inner lining may provide partial axial support to the filter media. An outer lining may also be included and provide partial axial support to the filter media.

摘要： An endcap including a first plate member including a radial inner portion, a radial outer portion, and defining a longitudinal axis. The endcap also includes a flange disposed between the radial inner and outer portions of the first plate member and projecting axially along the longitudinal axis in a first direction. The endcap also includes a first seal member disposed adjacent the flange. The first seal includes a first portion thereof engaged with an axial facing surface of the first plate member and a second portion thereof engaged with a radially facing surface of the flange. The endcap further includes a second plate member disposed radially outward of the radial outer portion and a second seal member disposed adjacent the second plate member including at least a portion thereof axially spaced from the axially facing surface of the first plate member in a second direction along the longitudinal axis opposite the first direction.
