20080245719 | Filter Element And Filter Assembly Including Locking Mechanism - A fluid filtering apparatus and method may include keyed components to ensure that a correct filter element is being installed into a filter base. Keyed arrangements may occur between a filter element and a filter housing, a filter and a filter base, and a filter base and a filter housing. A locking arrangement may be provided to prevent undesired loosening of a filter relative to a filter base. The filter base may include a torsion lock insert that engages lock detents of a filter to prevent the undesired loosening. An adaptor may be provided to provide the lock detents that interact with a torsion lock insert. | 10-09-2008 |
20090308801 | Fluid Filter, Fluid Filter Assembly, And Mounting Method - A filter and filter element is provided that incorporates a valve member for preventing priming fluid from contaminating a clean fluid side of the filter or filter element. The filter may incorporate a replaceable filter element or be replaceable itself. The valve member is preferably formed as an annular flange of a grommet mounted to an end cap of the filter element. The annular flange sealingly engages with the end cap and closes a clean fluid outlet port in a relaxed state and opens the clean fluid outlet port in a deformed state. | 12-17-2009 |
20090308802 | Filter With Ejection Mechanism - A filter system having a filter element ejection device is provided. Filter systems according to the present invention may include a filter element that includes an ejection receiver for receiving actuation action from an ejector of a filter housing. The ejector engages the ejection receiver when a user desires to eject the filter element from the filter housing. Typically, the ejector extends through the filter housing and axially ejects the filter element from the housing. | 12-17-2009 |
20090308803 | Filter With Water Separation Device - A filter, filter element and filter assembly are provided. The filter includes a water separating device for separating water from a dirty fluid flow. The water separator includes a fluid flow path that varies in cross-sectional area to vary pressure of the fluid therethrough. A top portion of the water separator is formed as a structurally independent piece from a bottom portion of the water separator. The top portion may be permanently or releasably secured to filter media of the filter via an end cap coupled to an end of the filter media. The bottom portion may be integrally or releasably secured to a housing of the filter. The bottom portion may also be integrally formed with a center tube upon which a filter element mounts. | 12-17-2009 |

The filter base may include a torsion lock insert that engages lock detents of a filter to prevent the undesired loosening. An adaptor may be provided to provide the lock detents that interact with a torsion lock insert. | 02-16-2012 |
20120125832 | FLUID FILTER, FLUID FILTER ASSEMBLY, AND MOUNTING METHOD - A filter and filter element is provided that incorporates a valve member for preventing priming fluid from contaminating a clean fluid side of the filter or filter element. The filter may incorporate a replaceable filter element or be replaceable itself. The valve member is preferably formed as an annular flange of a grommet mounted to an end cap of the filter element. The annular flange sealingly engages with the end cap and closes a clean fluid outlet port in a relaxed state and opens the clean fluid outlet port in a deformed state. | 05-24-2012 |
20120223001 | FILTER AND CENTER TUBE WITH HELICAL FIN - An apparatus and method for filtering a liquid utilize a filter apparatus including a center tube or flow balancing element including a helical fin. The helical fin radially contacts and supports the inner periphery of a filter media. The helical fin may be formed on a venturi center tube, or on a center tube flow balancing element for dividing the total flow of fluid through the filter apparatus into a bypass filter portion and a full-flow filter portion. The helical fin may alternately be formed on a standpipe center tube, defining a helical flow path between the inner periphery of a filter media and openings in the wall of the center tube. | 09-06-2012 |
20120273406 | Filter With Ejection Mechanism - A filter system having a filter element ejection device is provided. Filter systems according to the present invention may include a filter element that includes an ejection receiver for receiving actuation action from an ejector of a filter housing. The ejector engages the ejection receiver when a user desires to eject the filter element from the filter housing. Typically, the ejector extends through the filter housing and axially ejects the filter element from the housing. | 11-01-2012 |
20130193054 | FILTER APPARATUS WITH EJECTION ARRANGEMENT - A filter cartridge including catches for ejecting the filter cartridge from a filter housing as the filter cartridge and filter housing are removed from a filter base is provided. The catches are configured to engage corresponding catches of the filter base to limit axial motion of the filter cartridge as the filter cartridge and filter housing are threadedly removed from the filter base. | 08-01-2013 |
