Abstract: 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.

Abstract: A filter system for filtering fluid has a filter housing with inlet socket and outlet socket for fluid. A central tube with radially open region over a portion of its axial length is arranged in the filter housing in flow communication with the outlet socket in an operating state. Within the central tube, a secondary element is arranged slidably between first and second operating positions. A filter element, separating a raw fluid side from a clean fluid side, has a filter bellows with a first end plate at a first end face and a second end plate at a second end face. The end plates have central openings for receiving the central tube in the filter element interior. In the first operating position, the secondary element opens a fluid path through the radially open region of the central tube and closes the fluid path in the second operating position.
