Publication number: 20160030865Abstract: A cartridge forming part of a fluid filter includes a filter element, an end cap overlying one end of the filter element, a central tube having one end secured to the end cap, a biasing element, and a relief valve having a valve piston with a head that is biased by the biasing element into engagement with a valve seat formed by an underside of the end cap. The valve seat is configured so that it has a curvature that is larger than that of the head of the valve piston. In the particular arrangement disclosed, a second end cap overlies another end of the filter element, axially opposite the end cap mentioned, and is also secured to the central tube. Preferably, at least one of the central tube and the valve piston defines a depending pilot for supporting an end of the biasing element.Type: ApplicationFiled: March 13, 2014Publication date: February 4, 2016Inventors: Rajan AHUJA, L.

Patent number: 9095795Abstract: An anti-drainback valve contains a locking mechanism for securing the valve into to a filter assembly. The locking mechanism is made up of at least two keys that extend from the valve into beyond a cap of the filter assembly in order to secure the valve within the filter assembly. When multiple keys are employed, such keys may be equally spaced around the circumference of the cap. Manufacturing costs are kept minimal as minimal material is required and a two part mold may be employed during manufacturing.Type: GrantFiled: February 27, 2008Date of Patent: August 4, 2015Assignee: MANN+HUMMEL Purolator Filters LLCInventors: Rajan Ahuja, L.

Patent number: 8480885Abstract: A fluid filter has an outer case with a side wall, a closed first end wall, and a second end wall defining fluid inlet and outlet openings, as well as a filter cartridge received within the outer case. The filter cartridge includes a substantially cylindrical full flow filter element, providing for passage of a major portion of fluid entering the filter, and a substantially cylindrical bypass filter element, providing for passage of a minor portion of fluid entering the filter and disposed radially within and surrounded circumferentially by the full flow filter element. By way of the particular fluid filter configuration disclosed, a simple alternative to known filters having full flow and bypass filters located in common housings is provided.Type: GrantFiled: May 18, 2009Date of Patent: July 9, 2013Assignee: Purolator Filters NA LLCInventors: Theodore Michael Bryson, L.

Patent number: 8157989Abstract: A filter includes a housing having a cavity. A media pack, which includes a filter media, is arranged within the cavity and includes a central opening extending between opposing ends of the media pack. A center tube is arranged within the central opening and extends out of the central opening beyond one of the ends to provide a first end. A relief valve is supported on the first end. The filter cartridge assembly is installed into the housing with the relief valve in sealing engagement with a tapping plate of the housing. The relief valve performs the function of a seal between the filter cartridge assembly and the tapping plate in addition to performing pressure relief functions.Type: GrantFiled: April 10, 2006Date of Patent: April 17, 2012Assignee: Purolator Filters NA LLCInventors: Allen Buhr Wright, L.

Patent number: 8152996Abstract: A filter is provided having a housing that includes a cavity. A center tube includes first and second ends spaced from one another. A seat extends radially from the center tube and is arranged between the first and second ends. A media pack is arranged within the cavity and supported on the seat such that the center tube extends through a central opening of the media pack. An anti-drainback valve is supported on the seat and is in sealing engagement with the center tube and the media pack. The housing includes a tapping plate that provides an inlet and outlet. An annular lip of the anti-drainback valve is in sealing engagement with the tapping plate when in a closed position in which the engine is shut off.Type: GrantFiled: April 24, 2006Date of Patent: April 10, 2012Assignee: Purolator Filters NA LLCInventors: Allen Buhr Wright, L.

Patent number: 7959804Abstract: A filter media includes a media pack having a central opening that extends between opposing ends of the media pack. A support member, such as a center tube, extends through the central opening and supports one of the opposing ends. A second support member, such as a guide, is secured to the second support member and supports the other of the opposing ends. The guide loads the components within the filter to provide desired sealing. The guide is provided by flexible plastic tabs in one example and by an elastomeric grommet in another example.Type: GrantFiled: December 18, 2006Date of Patent: June 14, 2011Assignee: Purolator Filters NA LLCInventors: Allen Buhr Wright, L.

Patent number: 7857970Abstract: A filter media includes a media pack having a central opening that extends between opposing ends of the media pack. A support member, such as a center tube, extends through the central opening and supports one of the opposing ends. A second support member, such as a filter cartridge assembly guide, is secured to the second support member and supports the other of the opposing ends. In one example, the center tube includes a seat that extends radially outwardly from an axially body of the center tube to support the media pack. The first and second support members are secured by an interlocking connection of any suitable configuration. The disclosed arrangement can be used to reduce the number of components required for providing a large number of filter cartridge assembly. Each of a plurality of media packs provide different heights. A first support member is selected to support one of the opposing ends. A second support member is selected to accommodate the height of the selected media pack.Type: GrantFiled: April 24, 2006Date of Patent: December 28, 2010Assignee: Purolator Filters NA LLCInventors: Allen Buhr Wright, L.
