Patent number: 6676721Abstract: A V-pack filter includes a frame construction having a first frame structure and a second frame structure. The V-pack filter also includes first and second panel sections mounted in extension between the first and second frame structures. The first panel section has first and second ends. The second panel section has third and fourth ends. The first and third ends have a first distance therebetween while the second and fourth ends have a second distance therebetween. The second distance is generally greater than the first distance. The first and second panel sections and the second frame structure define an air flow aperture. A seal arrangement circumscribes the air flow aperture and projects outwardly from the second frame structure. The first frame structure defines a first receiver indent. Assemblies and methods are also included.Type: GrantFiled: April 12, 2002Date of Patent: January 13, 2004Assignee: Donaldson Company, Inc.Inventors: Gary R. Gillingham, Stan M. Koehler, William J. Krisko, Thomas G. Miller, Winston E. Olson, Fred H. Wahlquist, Ervin P. Fuchs, Eugene D. Wilson

Patent number: 6673136Abstract: Filter arrangements include a barrier media in the form of fluted media treated with a deposit of fine fibers. The media is particularly advantageous in high temperature (greater than 140 to 240° F.) systems. Such systems may include engine systems, gas turbine systems, and fuel cell systems. Filter arrangements may take the form of media packs having a circular cross-section or a racetrack shaped cross-section, or media packs formed in a panel configuration.Type: GrantFiled: May 31, 2001Date of Patent: January 6, 2004Assignee: Donaldson Company, Inc.Inventors: Gary R. Gillingham, Mark A. Gogins, Thomas M. Weik

Publication number: 20030121845Abstract: Fluted filter media includes filter material having a plurality of flutes formed therein having alternating ends of adjacent flutes closed to force fluid through filter material. A first embodiment of the filter media includes tapered flutes which have the open ends of the flutes larger in cross-section than the closed flutes, wherein the upstream open flutes converge toward the downstream end and the upstream closed end flutes diverge toward the downstream end. A second embodiment includes filter media which is asymmetric formed with dissimilar upstream and downstream flute cross-sections with larger flute openings to the upstream side of the filter. A third embodiment includes filter media with an upstream edge crushed to improve flow at the upstream edge. A fourth embodiment includes filter media with the upstream sealing material recessed from the upstream edge for reducing effects from blockages at the upstream edge of the filter.Type: ApplicationFiled: February 21, 2003Publication date: July 3, 2003Applicant: Donaldson Company, Inc.Inventors: Wayne M. Wagner, Gary R. Gillingham, Joseph C. Tokar, Daniel T. Risch, Jim C. Rothman, Fred H. Wahlquist, Bernard A. Matthys, Gregory L. Reichter, Stephen W. Sabelko, Bryan D. Patten

Patent number: 6213146Abstract: A valve assembly includes a housing and a float. The housing is constructed and arranged to inhibit movement of the float between a resting position to a position where it is situated in its valve seat, unless a selected liquid volume within the valve housing is attained. In one embodiment, a series of projection members or rings creates a tortuous path, such that there is no clear path for the float to reach the valve seat. In another embodiment, vacuum pressure is created between the float and its cup support. Still other embodiments utilize magnets, springs, linkages, and bent wires. Methods for preventing liquid ingestion into an engine through an air intake are also provided.Type: GrantFiled: December 7, 1999Date of Patent: April 10, 2001Assignee: Donaldson Company, Inc.Inventors: Daniel T. Risch, Gary R. Gillingham, Fred H. Wahlquist, Wayne M. Wagner, Joseph C. Tokar, Bernard A. Matthys, Pete A. Betts

Patent number: 5902364Abstract: A conical filter device inserts into a duct having flow passing from upstream to downstream. The filter device includes fluted filter media having flutes formed therein and a housing. The filter forms a seal between the outer edge of the filter at the downstream side and the housing. The upstream face of the filter is conical shaped in a first embodiment and frusto-conical in a second embodiment with the housing roughly corresponding to the shape of the filter. The filter elements are formed by winding layers of filter media to form a circular cross-section. The elements are moved axially as they are wound or placed on a shaping form while the sealant is still pliable to shape the element.Type: GrantFiled: April 26, 1996Date of Patent: May 11, 1999Assignee: Donaldson Company, Inc.Inventors: Joseph C. Tokar, Gary R. Gillingham, Wayne M. Wagner, Daniel T. Risch, Jim C. Rothman, Fred H. Wahlquist, Edward A. Steinbrueck, Steven A. Carter

Patent number: 5895574Abstract: A filter apparatus includes a fluted filter element in a filter housing having a first open end and a second closed end. The filter element includes fluted filter media coiled into a cylindrical shape and may include an end cap for support and fluid control. Fluid flows into the open end and either around the filter to the closed and back through the filter element or through the filter element to the closed end and then back through a central opening in the filter element.Type: GrantFiled: April 26, 1996Date of Patent: April 20, 1999Assignee: Donaldson Company, Inc.Inventors: Francis A.
