  • Patent number: 9061222
    Abstract: An apparatus and method for filtering a liquid utilize a filter apparatus including a bypass filter, a full flow filter, and a flow balancing element for dividing a total inlet flow of fluid to the filter apparatus into a bypass portion, passing through the bypass filter, and a full flow portion, passing through the full flow filter. The bypass filter has a lower filtering efficiency than the full flow filter element, so that a venturi tube is not required for causing the bypass portion to pass through the bypass filter. The flow balancing element divides the flow into a desired bypass portion and a desired full flow portion, at a predetermined operating temperature. Below the operating temperature, the bypass portion increases and the full flow portion decreases, the bypass portion becoming greater than the full flow portion at a second predetermined temperature below the operating temperature.

    Abstract: An oil filter assembly is disclosed for a machine, such as an internal combustion engine, that has an oil output port and an input port. A mounting plate is fixed with an outer enclosure. 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 portions of the outer enclosure. Oil passes through the pressure actuated valve only when an oil pressure differential between the peripheral and central portions exceeds a threshold pressure. A secondary filter has a second porosity greater than the first porosity, and is fixed between the pressure-actuated valve and the central portion.

The filter base may be situated inline, and in fluid communication, with influent and effluent piping, such as within a refrigerator. The filter housing assembly may be attached to, and removed from, the filter base by a push-actuated release. Upon insertion, the filter key shifts the filter lock longitudinally to receive interlocking segments. Upon extraction, the same axial push shifts the filter lock further to align the interlocking fingers within gaps that allow for easy extraction. The specific key lock design allows a user to identify and match certain filter configurations received by the mechanical support, and reject other filter configurations.

The filter housing assembly may be attached to, and removed from, the filter base by a push-actuated release. Upon insertion, the filter key shifts the filter lock longitudinally to receive interlocking segments. Upon extraction, the same axial push shifts the filter lock further to align the interlocking fingers within gaps that allow for easy extraction. The specific key lock design allows a user to identify and match certain filter configurations received by the mechanical support, and reject other filter configurations.

  • Patent number: 8365924
    Abstract: The present disclosure is directed to a manifold for a filter assembly. The manifold includes a first base which may define a first inlet configured to direct fuel flow to a first filter element, and a first outlet configured to direct fuel flow from the first filter element to the second filter element. The manifold includes a second base operably coupled to the first base. The second base may define a barrier which prevents the fuel flow from flowing from the first inlet to the second filter element without passing through the first filter element. The second base may also define a second inlet configured to receive fuel flow from the first outlet and direct the fuel flow to the second filter element, and a second outlet configured to receive the fuel flow from the second filter element.

    Abstract: A filter unit includes a body portion having a proximal end and a distal end and a shoulder disposed therebetween. An engagement protrusion extends from the proximal end. The engagement protrusion includes a sidewall with a water inlet and an engagement wall with a water outlet. A cross-section of the engagement protrusion taken orthogonal to the longitudinal extent of the filter unit has only one axis of symmetry. A first engagement surface traverses approximately one-quarter of an outside circumference of the body portion. A second engagement surface traverses approximately one-quarter of an outside circumference of the body portion opposite the first engagement surface. A laterally extending key member is disposed on the body portion proximate the shoulder. An electronic device is positioned on the body portion adapted to store usage information relating to the capacity and usage of the filter unit.

  • Publication number: 20120223002
    Abstract: Disclosed is a capsule apparatus having a filter housing defining a filter chamber with a top cap having a plurality of ports extending substantially laterally from a top end of the top cap to reduce the overall dimensions of the apparatus. The lateral and substantially uniform orientation of the ports facilitates connection to panel mount assemblies and improves filter maintenance processes. A transfer tube extending the length of the capsule allows the introduction of heated fluids from a top mounted inlet port to a bottom of the capsule chamber to allow or a substantially uniform heat gradient in the capsule filter chamber. An alternative shield secured in the housing defines a first chamber in fluid communication with an inlet and a second chamber wherein the two chambers are in fluid communication via an opening defined by a lower end of the shield and a bottom of the filter chamber.

  • 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.
