  • Patent number: 9010365
    Abstract: The present invention provides an apparatus and method for filtering fluid in a breather assembly and providing uncontaminated fluid to a reservoir. The breather allows in-take fluid traveling through a first flow path to be filtered before entering the reservoir through a first directional valve. The breather also allows exhaust fluid traveling through a second flow path, separate from the first flow path, to exit through a second directional valve.

  • Patent number: 7771595
    Abstract: A filter element includes a ring of filtration media circumscribing a central axis, and first and second end caps. The first end cap includes i) an annular body portion defining a central opening around the central axis, sealingly bonded to the first end of the media ring, ii) an annular sealing ring having an annular, peripheral resilient sealing portion; and iii) axial support stanchions around the periphery of the body portion. The stanchions support the sealing ring at a location spaced apart from the body portion, and define radial flow openings between adjacent stanchions. One or more non-radial flow members extend from each stanchion along the outer surface of the annular body portion to direct flow in a spiral or helical manner, where the flow then passes through the flow openings and downwardly along the outer surface of the media in a swirling manner.

  • Patent number: 6887376
    Abstract: A hydraulic system includes a storage tank, a cover assembly and a filter assembly for filtering hydraulic fluid, gasses and air. The tank includes an opening and an attachment ring bounding the opening. The cover assembly has an inlet port and is removably connected to the attachment ring to support and enclose the filter assembly in the tank. The filter assembly includes a filter element having a filter media ring for filtering hydraulic fluid, and an annular breather filter surrounding the filter media ring at one end of the ring for filtering vent gas and air. The filter element is supported in a diffuser tube received in the tank opening. The diffuser tube includes a stand-off ring with a convoluted groove or channel to provide a vent path between the diffuser tube and the tank opening to direct vent gasses and ambient air through or around the breather filter.

  • Patent number: 6099729
    Abstract: A coreless filter element for a filter housing includes cylindrical filter media having longitudinally-extending pleats extending from one end cap on the filter media to another end cap on the filter media. The filter media is preferably a multi-layered structure with an outer support mesh layer attached to an inner prefiltration layer by an intermediate adhesive web layer. An inner wrap of a porous fibrous filter media is provided within the central cylindrical cavity of the pleated filter media. The wrap has a cylindrical form with an outer surface which is joined to the inner pleat peaks of the media such as with one or more beads of adhesive, or with a continuous adhesive layer applied to the outer surface of the support wrap. The filter element with inner support wrap can be easily located over a metal support core integral with the filter housing, and provides structural integrity for the pleats of the filter media.

  • Patent number: 4867095
    Abstract: A cartridge style, pop up, differential pressure indicator includes a threaded body member, a cover structure and a cylindrical indicator button, which carries a magnet at its lower end, and is slidably supported in the cover for movement between a depressed, hidden position and an extended indicating position. The button is engaged at one side by a leaf spring which in the depressed position urges a lip on the button under a ledge in the cover to serve as a detent. A piston slidably supported in the body is subject to differential fluid pressures and carries a magnet at its upper end, poled in a manner to repel the magnet in the indicator button to urge the latter against the bias of the detent spring and upwardly to the extended, indicating position. A semicircular bimetal strip supported in the cover engages the detent spring at lower temperatures to prevent false release of the indicator button due to cold weather, high fluid viscosity situations.

  • Patent number: 4815493
    Abstract: A three component bypass valve comprises molded nylon valve body and poppet elements and a retained spring. The valve body includes an annular valve head having a valve seat therein and an integral open sided spring housing in the form of a pair of spaced tracks joined by an end wall. The tracks and end wall serve as a poppet guide and spring retainer, the poppet having notches for mating support surfaces, while the open housing allows pivotal movement of the poppet for ready assembly or replacement of the poppet and spring. The valve head is externally threaded for placement of the valve in a threaded bore of a fluid filter and the like.
