Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A filter includes a filter housing having a tapping plate providing an inlet. A filter element assembly is arranged in the housing and includes an end disc. A bypass valve housing is arranged between the end disc and the tapping plate and supports a bypass valve. The bypass valve housing provides a cavity in fluid communication with the bypass valve. An anti-drain back valve is retained between the bypass valve housing and end disc. The inlet is in fluid communication with the cavity when the anti-drain back valve is in a closed position. The anti-drain back valve is over-molded to the bypass valve housing. The bypass valve housing including first and second portions secured to one another, for example, by ultrasonic welding. The first portion provides a spring seat, and the second portion includes first, second and third walls generally concentric with one another. The first and second walls provide a cavity, and the second wall is arranged between the first and third walls.

Abstract: A filter uses a reversible element guide. The filter includes a housing that provides a cavity. A filter element assembly is arranged in the cavity and includes an end cap supporting the filter media. An element guide is arranged between the end cap and the housing. The element guide includes a first set of tabs engaging the end cap and a second set of tabs engaging the housing. The number of tabs in each set are equal to one another so that they will exert the same biasing force when installed in either orientation. The tabs extend away from a base at a height that is the same on each side of the base.

Abstract: A delivery device for a chemical additive is provided for an oil filter. A carrier supporting a chemical additive is arranged within a central opening of a pleated filter media. The carrier interlocks with a center tube, also arranged within the central opening, that supports that filter media. The carrier includes fingers that axially and radially locate the carrier to prevent movement of the carrier within the filter.

Abstract: A fuel module includes a fuel pump having a fuel inlet and fuel outlet. The module also includes a fuel filter having a filter inlet and a filter outlet. The module has a housing with a body that defines a cavity. The fuel pump and fuel filter are arranged in the cavity. The housing includes a removable end cap that at least partially encloses the cavity in an installed position and provides access to the cavity in a service position. Fastening elements such as threaded fasteners secure the removable end cap to the body in the installed position. Seals are arranged between the fuel pump and fuel filter and the end cap when in the installed position. The end cap also includes caps secured to a surface of the end cap to provide fluid passages where necessary. When the fuel pump or fuel filter requires replacement, the threaded fasteners and end cap are removed from the body, and the fuel pump and/or fuel filter may be detached from the end cap.

Abstract: Disclosed herein is an apparatus for marketing automobiles. The device comprises a receptacle (preferably tubular) that may be attached to the automobile without risk of damage to the automobile. The receptacle may be used to contain documents providing information about the automobile to prospective purchasers.

Abstract: An oil filter includes a housing defining a cavity. The housing includes an aperture for providing fluid to the cavity. A filter assembly having a filter media is arranged in the cavity and separates the cavity into an inlet side and an outlet side. A relief valve assembly has a relief valve movable to selectively fluidly connect the inlet and outlet sides to bypass the filter media. An anti-drain back valve includes a closed position sealing the aperture in the housing from the cavity while permitting a fluid connection between the aperture in the housing and the relief valve. The relief valve assembly includes a relief valve retainer supporting the relief valve. The anti-drain back valve includes a wall spaced from the relief valve retainer forming a chamber. Apertures in the wall and holes in the relief valve fluidly connect the aperture of the housing to the relief valve throughout various positions of the anti-drain back valve.

Abstract: A fluid filter includes a housing having a tapping plate with a first aperture. A center tube is arranged in the housing proximate to the tapping plate. The center tube includes a second aperture. An elastomeric valve assembly is arranged between the center tube and the tapping plate. The valve assembly comprises a separate two-piece relief valve and anti-drain back valve. The anti-drain back valve is arranged adjacent to the first aperture for selectively blocking the first aperture to prevent fluid from exiting in the side of the filter during engine shut down. The relief valve is arranged adjacent to the second aperture for selectively blocking the second aperture to permit fluid to flow past the relief valve during high differential pressure conditions such as cold starts and plugged filter conditions.

Abstract: A fluid filter includes a housing having a tapping plate with a first aperture. A center tube is arranged in the housing proximate to the tapping plate. The center tube includes a second aperture. An elastomeric valve assembly is arranged between the center tube and the tapping plate. The valve assembly comprises an integrated, one-piece relief valve and anti-drain back valve. The anti-drain back valve is arranged adjacent to the first aperture for selectively blocking the first aperture to prevent fluid from exiting in the side of the filter during pressure drops. The relief valve is arranged adjacent to the second aperture for selectively blocking the second aperture to permit fluid to flow past the relief valve during high pressure conditions such as cold starts.
