Filter Element Attached To Closure Patents (Class 210/454)
  • Publication number: 20150122724
    Abstract: The present invention presents a filtration system with an integrated manifold valve. The filtration system employs only one pivotal component—the pivoting of the manifold. The manifold valve includes a dual aperture design for a two-fold alignment scheme with the ingress and egress lines of the fluid source. The invention is free of multi-component rotary valve with internal, rotatable parts, or an activation component, such as a handle, for initiating the rotary valve, allowing the user to rotate the rotational components thereof. The reduction in moveable components in this design reduces the likelihood of failure and increases the reliability of the filtration system.

The filtering apparatus dispenses with the need for O-seals that are known in prior art and extend in a radial direction between the filter element and the filter head as a housing lid because the sealing device (60) encompasses at least one sealing edge (62) or sealing surface placed parallel to the longitudinal axis in a radial direction and seals under the effect of the pressure applied it by the holding mechanism (38).

  • Patent number: 7799216
    Abstract: Drain trap assembly for separating sediment from discharged wastewater including a conduit with a first upper inlet portion and a second upper outlet portion. Between the inlet and outlet is located a lower bend portion. Interrupting the lower bend portion is a third conduit portion including a cup closure for sediment accumulation out of the wastewater pathway. Affixed to the cup closure and extending generally upwardly within the assembly and across the wastewater flow is a strainer including at least one plate with through-holes sized to reject particulate sediment and other solids of a predetermined size. Another strainer embodiment includes fibers affixed to the closure and extending across the wastewater flow. A strainer support leg may be concave to guide or deflect sediment-laden wastewater downwardly to the accumulation area and may include at least one wastewater flow aperture. Closure removal automatically withdraws the strainer, offering ready access to accumulated sediment.

  • Patent number: 7578287
    Abstract: In a fuel filter for an automobile, a filter element for filtering fuel is accommodated in a tubular filter case having a bottom surface and a side surface. A fuel heater is mounted on the side surface of the filter case. Therefore, the filter case and the filter element can be heated directly from heat generated by the fuel heater to effectively heat the fuel flowing therethrough, thereby preventing precipitation of a wax component that could clog the filter element. Also, fuel supply passages for supplying the fuel to the filter element are formed along the side surface of the filter case. Therefore, the fuel is brought into sufficient contact with the filter case heated by the fuel heater, thereby effectively heating the fuel.

  • Publication number: 20090127185
    Abstract: The invention relates to a filter element for filtering fluid for a motor or gearing, comprising a first filter medium which is arranged in a cylindrical way, with the fluid impinging in a perpendicular way on the circumferential surface of the first medium for filtering in an associated filter apparatus, then penetrating and passing through the same. The filter element comprises a second filter medium with a filter density differing from the first filter medium, the first filter medium and the second filter medium being stacked upon each other as filter layers and being jointly wound in a spiral manner. A desired purity of the fluid can thus be achieved more quickly than in filter elements which exclusively allow a radial passage of the fluid through the filter elements. The spiral configuration also achieves a higher dirt absorption capacity.
