    摘要： A liquid filter assembly comprises a filter cartridge and a filter head in fluid communication with the filter housing. 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. The filter head includes an inlet for conveying liquid to the unfiltered liquid volume, a first outlet for conveying liquid from the filtered liquid volume, and a second outlet. A first valve assembly is provided which is constructed and arranged to selectively permit passage of liquid from the unfiltered liquid volume through the second outlet, in response to a first selected liquid pressure level within the unfiltered liquid volume. A second valve assembly is disposed within the filter head and is constructed and arranged to selectively permit passage of liquid from the filtered liquid volume through the second outlet in response to a second selected liquid pressure level within the filtered liquid volume.

    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 filter cartridge including a liner/valve, or support/valve construction is provided. The liner/valve construction provides for contaminant flow to the filter media during normal filtering operation, and contaminant or sediment retention in the cartridge during a servicing operation. The preferred liner/valve construction includes an outer support having a flexible sheet valve positioned therein. The preferred sheet valve includes a plurality of cut valves. Methods of construction, assembly and use are provided.
