    Abstract: An apparatus comprising a pressure limiting valve for preventing transmission of elevated pressure to components downstream of the apparatus. Preferably, the pressure limiting valve is used in combination with a flow regulating device that maintains a substantially steady flow rate through the apparatus even when subject to a wide range of applied pressure. The apparatus of the present invention is preferably suitable for use with filter systems wherein the pressure limiting valve is placed upstream of filter components that have limited burst and fatigue life capabilities. By isolating the downstream filter components from pressures that are greater than the target pressure range for a given application, the filter components can be designed to operate at much lower pressure, can be produced at a smaller size, and at a reduced cost.

    Abstract: A filtration system interconnection structure having a filter manifold and a filter cartridge in magnetic communication with one another, such that a latching mechanism and latch blocking structure in the manifold secures the filter cartridge with a manifold sump when the filter cartridge is inserted within the manifold sump. The magnetic communication is formed between two complementary coded magnets capable of producing a magnetic shear force when in close proximity to one another. The magnetic shear force removes the latching blocking structure from interfering with the latch, allowing the latch to secure the filter cartridge. The filter and the manifold magnet polarity transitions are aligned such that a shear force is generated between the magnets when the filter cartridge is inserted within the manifold sump housing, allowing for actuation of the latch blocking mechanism against a biasing force, and thereby move radially inwards against a separate biasing force.

    Abstract: A filtration system interconnection structure having a filter manifold including a sump housing and a first correlated magnet located on or connected to a portion of the manifold, and a filter cartridge including a filter media, first and second end caps sealed to the filter media, and a second, paired correlated magnet located on or connected to the filter cartridge housing body. The first and second correlated magnets are interconnected via magnetic communication upon insertion of the filter cartridge into the sump housing, and upon movement of the filter cartridge into an alignment position, the correlated magnet located on or connected to the manifold is permitted to translate as a result of the magnetic communication. The polarity profiles of the paired correlated magnets are aligned such that a repulsion force is created when the filter cartridge is inserted within the manifold sump housing.
