Abstract: An interconnection scheme between a filter cartridge and its corresponding manifold whereby a magnetic shear force is introduced to remove a blocking mechanism that would otherwise prohibit attachment. The magnetic shear force may also be employed to activate or deactivate a switch or valve, or engage or disengage an engagement mechanism relative to other components upon interconnection. The magnetic shear force is generated by complementary correlated magnet structures moved into close proximity to one another. The interconnection scheme may be a linear or rotational attachment of the filter cartridge with respect to the manifold. A valve assembly utilizing magnetic shear force may be employed to activate a bypass action between a manifold ingress port and egress port, thereby allowing water to flow when a filter cartridge is removed from the manifold and directing water to the filter cartridge when the valve assembly is activated.

The end edges form oppositely positioned end edge surfaces. The filter bellows is arranged in closed configuration about a longitudinal axis and encloses a hollow space. The filter bellows has opposed end faces sealed by an end disc. The filter bellows has a cut portion in at least one of the oppositely positioned end edge surfaces such that one or more regions of folds with shortened fold length are formed. A fold length of the folds with shortened fold length is substantially identical at an outer and inner circumference of the filter bellows.

Abstract: A filtration system interconnection structure includes a filter manifold and a filter cartridge in magnetic communication produced by two complementary correlated magnets capable of generating a magnetic force when in close proximity to one another. The filter magnet polarity transitions are aligned with the manifold magnet polarity transitions such that a repulsion force is generated between the magnets when the filter cartridge is inserted within the manifold sump. The magnetic repulsion force may be used to move a blocking mechanism or actuate a latch structure in the manifold to secure the filter cartridge within the manifold sump upon insertion, or to provide non-contacting actuation of a downstream valve so as to permit or prevent the flow of fluid. Utilizing correlated magnetism in a filter interconnect further provides enhanced authentication and/or anti-counterfeiting means to ensure that only authorized or OEM filter cartridges can be installed.
