    摘要： A spin-on filter cartridge includes a housing, a filter element operably oriented in the housing, a baffle plate, and a seal arrangement. The baffle plate is operably oriented over the housing open end. The baffle plate defines a central flow aperture. The baffle plate defines a continuous groove immediately adjacent to and circumscribing the central flow aperture. The seal arrangement is secured to the baffle plate spaced from and circumscribing the continuous groove. In another aspect, a filter assembly includes a spin-on filter cartridge as characterized above and a filter head. The spin-on filter cartridge is removably mountable on the filter head. The filter head includes a central spud defining outer threads. An O-ring seal member or a gasket seal member is operably oriented around the central spud. When the spin-on filter cartridge is operably oriented on the filter head, the seal member is received within the continuous groove and the seal arrangement forms a seal between and against the baffle plate and the filter head. The seal can be radial or axial or have both axial and radial components. In another aspect, a method of assembling a filter assembly includes spinning a filter cartridge as characterized above onto a filter head to form a primary seal between the baffle plate on the filter cartridge and the filter head, and until a seal member fixed to the filter head is received within the continuous groove. In another aspect, a filter head is provided. The filter head includes a block defining fluid flow channels; a central spud having a threaded outer wall; and a seal member secured to and circumscribing the central spud.

    摘要： The filter head and filter housing define a liquid flow inlet path, a first liquid flow outlet path, and a second liquid flow outlet path. A filter media construction is positioned within the housing. The filter media construction, in combination with the housing, defines an unfiltered liquid volume, and a filtered liquid volume. A first liquid flow inlet path directs liquid from the liquid flow inlet to the unfiltered liquid volume. A first liquid flow outlet path directs liquid flow from the filtered liquid volume to the first liquid flow outlet. A second liquid flow outlet path directs liquid flow from the filtered liquid volume to the second liquid flow outlet. A first valve assembly selectively opens the second liquid flow path to passage of liquid therethrough in response to a first selected liquid pressure level within the filtered liquid volume. A second valve assembly comprises a first bypass valve assembly, and selectively directs fluid flow from the unfiltered liquid volume to the second liquid flow outlet, in response to a second selected liquid pressure level within the unfiltered liquid volume.

    摘要： A liquid filter assembly includes a porous tubular support member and a filter element removably and replaceably oriented in the interior volume of the support member. A bypass valve arrangement is provided to permit at least some unfiltered liquid to bypass media in the filter element. A dynamic seal can help to seal the bypass valve arrangement.
