    Abstract: A filtration system interconnection structure having manifold with a rotatable manifold magnet of correlated magnets, a shroud with alignment tracks, an actuating valve for water ingress, and a filter cartridge having a rotatable filter magnet of correlated magnets, where the manifold magnet and the filter magnet are in magnetic communication with one another when the filter cartridge is inserted with the shroud, and are at least partially rotatably compatible, where the manifold magnet rotates with the filter magnet until the manifold magnet experiences a rotational stop beyond a predetermined rotation of the filter magnet, thus allowing the filter magnet to shift polarity with respect to the manifold magnet and present a repulsion force for removal of the filter cartridge from the shroud.

    Abstract: An in-line or in situ filter is disclosed for filtering fluid flowing through a hydraulic system, and particularly an automotive hydraulic system. The filter has a magnetic base with a central opening at its outlet end and a seat with a central opening at its inlet. The base and the seat are joined by a cylindrical filter element made of a magnetically susceptible mesh screen material. A spring within the filter element biases a ball against the central opening of the seat normally sealing off the opening and forcing fluid to flow through the filter element to be filtered before exiting through the central opening of the base. If the mesh screen becomes clogged, backpressure forces the ball away from the seat against the bias of the spring to allow fluid to bypass the filter element and flow directly through the filter. In the process, ferrous debris entrained within the fluid flow continues to be captured by attraction to the magnetic base and the magnetized filter element.

    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.

    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.

    Abstract: PROBLEM TO BE SOLVED: To provide an oil filter capable of effectively capturing the foreign matters such as worn metal powders contained in the oil circulating an oil path and also of preventing abnormal oil pressure elevation in the oil path when generating clogging.SOLUTION: The oil filter 1 has a container-like capturing portion 25 formed by a frame 10 and a meshed member 20 attached to the frame 10. The frame 10 is made of a ferrite injection molded magnet, includes at one end, an inflow opening 12 for flowing the oil thereinto, and is mounted in an oil passage 37 in such a manner that a flange portion 11 around the inflow opening 12 is magnetically joined to a metallic separate plate 35. When clogging occurs in the meshed member 20 and the pressure in the capturing portion 25 exceeds a prescribed level, the flange portion 11 is disengaged from the separate plate 35, and a gap generates between the opening 36 of the separate plate 35 and the inflow opening 12 of the oil filter 1 to make the oil bypass.
