    Abstract: A filter cartridge for use in filtering fluids, for example fuel, lubrication, hydraulic and other liquids, as well as air. The filter cartridge is a filter-in-filter design with an inner filter and an outer filter. The inner filter and the outer filter, for example the bottom end plates thereof, are connected to each other via a snap fit connection mechanism. During manufacture, the inner filter can be inserted into the outer filter, with the snap fit connection mechanism retaining the inner filter in the outer filter.

    Abstract: The present invention provides a filter assembly containing a filter element and a container as a depot for a liquid additive. The container can include an inlet and an outlet, which are configured to allow a liquid to flow into the container mix with the contained additive and then flow out into the system. It has been observed that a liquid flowing through a filter assembly exhibits a pressure gradient within the filter. Consequently, the inlets and outlets to the container can be positioned to take advantage of the pressure gradient to enhance the addition of the additive to the liquid in the filter assembly.

    Abstract: A filter assembly includes a housing and an inner post with a fluid inlet passage extending in the housing. An outer post surrounds the inner post to define a fluid outlet passage. A filter cartridge is received around the inner post and the outer post. The filter cartridge includes a filter element. A first endplate, which defines a first opening, is attached to a first end of the filter element. A first seal is received in the first opening to seal between the inner post and the first endplate. A second endplate, which defines a second opening, is attached to a second end of the filter element. A seal is received in the second opening to seal the outer post with the second endplate. The housing and the filter cartridge define an outer cavity. The fluid inlet passage opens into the outer cavity to minimize back flushing of contaminants.

    Abstract: A liquid filter (10) housing an annular filter element (16) has an annular space or inlet chamber (24) between the filter element and the housing and viewable through the housing such that an operator can see the level of liquid in the inlet chamber as an indication of when to replace the filter element, the higher the level of liquid in the inlet chamber the greater the pressure drop across the filter element. A change interval plugging indicator (102), preferably part of the filter element, is provided by a gas trap and pressure responsive release mechanism (104) trapping gas in the upper section (23) of the inlet chamber until a designated release pressure is reached, corresponding to a desired terminal pressure, to prevent premature plugging indication otherwise indicated by rising liquid level in the inlet chamber. Accurate and reliable calibration is enabled by separating the filtration function and the plugging indication function.

The rise in liquid level in the annular space is delayed for applications where the filter element is otherwise changed prematurely and has a longer life than otherwise indicated by the rising liquid level in the annular space. The delay is provided by a liquid and vapor impermeable sleeve (50) trapping vapor. In a further aspect, the sleeve is provided with apertures (70, 72, 74, 90, 92) filled by liquid-soluble buttons (76, 78, 80, 94, 96) providing filter element change interval indication, including advance sequential indication.

    Abstract: A fuel filter constructed and arranged for fuel-water separation which is designed with an integral fuel pump includes a unitary housing designed with a fuel filter cavity for receipt of a fuel filter cartridge, and a pump receptacle cavity for receipt of a fuel pump. A separating wall is disposed between the fuel filter cavity and the fuel pump cavity and this wall defines a flow passageway for fuel flow communication between the fuel pump and the fuel filter. Included as part of the fuel filter assembly is a lid designed to attach over the fuel filter cavity of the unitary housing and a lid designed to attach over the pump receptacle cavity of the unitary housing. The combining of the fuel filter cartridge and the cooperating fuel pump within the same unitary casting provides design efficiencies and economies.

    Abstract: A self-closing centerpost for a fluid filter includes a centerpost body which is constructed and arranged with a hollow interior so as to provide a fluid passageway. The fluid filter is designed for fuel and the hollow centerpost body includes an outer wall which defines a pair of flow apertures. These flow apertures are in flow communication with the fluid passageway in order to deliver fluid to the outlet port of the fluid filter. A control valve is positioned within the hollow interior and is designed with a pair of oppositely-disposed blocking portions which are disposed over the flow apertures when the flow control valve is in its normally closed (spring-biased) condition. In this closed condition, fuel is unable to enter the hollow centerpost body and is thus unable to be delivered to the engine. A biasing spring maintains the flow control valve in this closed condition until such time as a filtering element is installed at which point the endplate of the filtering element is used as the means to push down on a plunger portion of the flow control valve. Once the spring biasing force is exceeded by downward movement of the control valve, the blocking portions move away from the flow apertures so as to move the flow control valve into an open condition and permit fuel to flow through the flow apertures.

    Abstract: A filter seal for a substantially cylindrical air filter includes an integrally molded, polyurethane member which is configured with two primary portions. One portion is an annular body which is formed with an annular receiving channel, like a potting shell, which in turn is sized so as to receive one end of a corresponding filter element. The other portion is an annular sealing lip which is disposed in spaced relation to the receiving channel. This sealing lip includes a specific geometry providing both a ribbed, radial-sealing surface and a convex, axial-sealing surface. The radial-sealing surface provides sealing contact with a generally cylindrical outlet portion of the housing in which the filter element is placed in tension while axial sealing is achieved by compression of the axial-sealing surface against a generally planar surface of the housing. In addition to these two modes of sealing engagement, when the unit is in operation as part of a vehicle, differential pressure forces cause the sealing lip to press more tightly against the housing so as to enhance the sealing. The molding process which completes the fabrication of the filter seal concurrently bonds the filter seal to the filter element.
