Publication number: 20240066444Abstract: Liquid filter assemblies, features, components and methods are described. In general, a liquid filter cartridge is provided which includes features that help ensure that when the assembly is serviced, the cartridge positioned within the assembly is a proper one, in proper sealing orientation, for appropriate use. Features that can be used to provide for this include: a seal on the filter cartridge that defines a seal pattern non-orthogonal to a plane perpendicular to a central axis of the filter cartridge; and, a member of a projection/receiver arrangement on the filter cartridge which is orientated to engage a portion of a liquid filter assembly, for example a liquid flow collar, to allow sealing when the cartridge is a properly positioned cartridge and a properly configured cartridge. Assembly features are described. Also, a flexible radial projection arrangement providing snap-fit interaction between a cartridge and housing is provided. Methods of assembly and use as described.Type: ApplicationFiled: November 9, 2023Publication date: February 29, 2024Inventors: Luca Piva, Fabrizio Buratto, Jason P.
