  • Patent number: 8679334
    Abstract: A power steering fluid filter includes a housing that defines an interior chamber, an inlet port communicating with the upstream end of the interior chamber, and an outlet port communicating with the downstream end of the interior chamber. A movable thimble filter is disposed within the housing and an annular magnet is located at the mouth of the thimble filter. A spring biases the thimble filter and magnet toward the inlet port of the housing. In use, power steering fluid passes through the housing and debris is captured by the thimble filter. Ferrous particles entrained in the fluid flow are attracted to and captured by the magnet. When the thimble filter becomes clogged, it is displaced by the pressure of the fluid against the clogged filter so that fluid can flow around and bypass the thimble filter while still being exposed to the magnet for removing ferrous particles.

  • Patent number: 8573407
    Abstract: A lubricant reclamation system having a moisture absorbent cartridge (140). The cartridge (140) is fabricated placing a Superabsorbant Polymer (SAP) (142) within a boundary of polyester mesh (143). Moisture is extracted from a lubricant or other fluid and absorbed by the SAP. The moisture latent SAP bonds to the polyester mesh (143), potentially turning into a gel. A layer of polypropylene sorbent (144) is placed about the exterior of the boundary material (143), ensuring any moisture remains exterior to the sorbent layer (144). A resin layer can optionally be placed within a fluid flow following the discharge from polypropylene sorbent extracting aerosol from within the lubricant and as a barrier of detrimental ions with an exchange of beneficial ions. The entire cartridge can be placed within an enclosure or pouch body (162). The body (162) is designed to expand, accommodating a resultant increase in SAP volume. The cartridges can be integrated into filters comprising commonly known filtration elements.

    Abstract: A fuel water separator (FWS) filter that is configured to permit water to be drained from the water sump of the FWS filter without shutting off fuel flow to the FWS filter. A check valve is positioned between the water sump and the filter element. When the FWS filter is under vacuum (e.g. as in operation), the check valve can be closed to allow water to drain from the sump. The check valve can close automatically by floating on accumulated water in the sump until the water rises to a level where the check valve is closed. The check valve can also close by opening the drain valve of the FWS filter, which causes a differential pressure between the sump and the vacuum created in the filter element chamber, which forces the check valve to close.

  • Patent number: 8333890
    Abstract: A filter within a filter cartridge design is described that includes a sealing structure on an endplate of an outer filter element. Generally, the sealing structure includes an annular flange on the endplate that can directly seal against an interior surface of a housing when the filter cartridge is assembled for use. During filtration, the annular flange prevents a working fluid from bypassing the outer filter element. The sealing flange can seal with the housing in a press fit engagement.

  • Patent number: 8216470
    Abstract: A filter cartridge is described that is designed to accommodate for example dual stage filtration. The filter cartridge has an endplate structure formed of a heat cured material, such as polyurethane, where at least one of the top end and the bottom end of the outer filter and the inner filter are embedded within the heat cured material. The heat cured material can provide an endplate structure that is convenient for manufacture and that has one or more sealing surfaces to seal with a housing that the filter cartridge is assembled with. For example, the heat cured material of the endplate can seal non-filtered fluid from filtered fluid that has passed through each of the filtration stages available in the cartridge.

  • Publication number: 20120138523
    Abstract: Disclosed is multi-flow filter cartridge assembly that includes an elongated housing that has axially opposed proximal and distal ends and defines an interior cavity and first, second and third flow paths which extend from the proximal end of the housing to the distal end. The cartridge assembly also includes first, second and third filter elements. The first filter element is disposed within the interior cavity of the housing and conditions fluid that traverses the first flow path from a first inlet port to a first outlet port. The second filter element is disposed within the interior cavity of the housing and conditions fluid that traverses the second flow path from a second inlet port to a second outlet port. Lastly, the third filter element is also disposed within the interior cavity of the housing and conditions fluid that traverses the third flow path from a third inlet port to a third outlet port.

  • Patent number: 8187458
    Abstract: An oil filter assembly is disclosed for a machine, such as an internal combustion engine, that has an oil output port and an oil input port. A mounting plate is fixed with an outer enclosure and is adapted for securing to the machine. The mounting plate is further adapted to conduct oil from the machine into a peripheral portion of the outer enclosure, and then returning oil from a central portion of the outer enclosure back to the machine. Oil may pass from the peripheral portion to the central portion through a primary filter having a first porosity. A pressure-actuated valve is fixed fluidly between the peripheral portion and central portion of the outer enclosure. Oil may pass through the pressure-actuated valve only when an oil pressure differential between the peripheral portion and the central portion of the outer enclosure exceeds a predetermined threshold pressure.

  • Patent number: 8136674
    Abstract: A filter device includes a filtering member having a rough part, which is comparatively low in a density of flow pores for flowing fluid, and a dense part, which is comparatively high in the density of the flow pores. The filter device further includes a support member that supports the filtering member and has an inflow passage and a discharge passage. The dense part supports the rough part, and is located between the rough part and the discharge passage, and is supported by a mechanical pressure applied by the support members. The filter device is capable of supporting the filtering member easily in a case member and securing a filtering area to enhance the performance of removing a foreign matter.

  • Publication number: 20120024768
    Abstract: A water-conducting household appliance, in particular a dishwasher, includes a hydraulic circuit for circulation of a wash fluid, and a filter facility which includes a filter element having an inner wall and at least one filter opening for passage of the wash fluid. The filter opening is bounded by the inner wall running around the filter opening. The inner wall has an upstream wall segment and a downstream wall segment, with a gradation being formed at least in a segment between an upstream and downstream wall segment of the inner wall of the filter opening. Additionally or independently hereof, the downstream wall segment has a cross section that increases in a flow direction of the wash fluid.

  • Patent number: 8043504
    Abstract: A filter cartridge that is designed to accommodate differences in lengths between an outer filter media and an inner filter media by providing a flexible connection between the inner filter media and the outer filter media. In addition, the endplates of the inner filter and the outer filter together define a gasket groove that receives a gasket. Using the endplates of the inner and outer filter media to define the gasket groove eliminates a mold parting line that can lead to fluid leakage.
