Abstract
A fuel filter assembly incorporates a modular drain bowl which may be removably mounted at the lower end of the disposable filter cartridge. An anchor insert is disposed interiorly at the lower portion of the cartridge sump for anchoring a fastener to attach the drain bowl. The insert also is specially configured to form outlet passages which facilitate the flow of water from the sump to the drain bowl.
Claims19
A modular fuel filter assembly comprising:
- base means comprising receptacle means, inlet and outlet means and fluid passage means communicating with said inlet and outlet means;
- cartridge means comprising filter means and housing means for housing said filter means, said housing means being receivable by said receptacle means, said housing means having an axis and opposed first and second end portions spaced axially along said axis, said first end portion having first opening means defining an axial opening extending axially along said axis for receiving said fluid passage means, said second end portion defining a sump interiorly of said housing means and comprising second opening means for defining a second opening for said sump, anchoring means mounted interiorly of said housing means adjacent said second end portion at a central position thereof for anchoring a fastener;
- retaining means for releasably securing said cartridge means to said base means;
- bowl means for forming a covered bowl for retaining fluid, said bowl means being mountable to said cartridge means exteriorly of said housing means adjacent said second end portion, said bowl means comprising a bowl member and a cover member which substantially covers said bowl member to form said covered bowl, said cover member having a surface which is generally complementary to the exterior surface of said second end portion, and said bowl means comprising communication means to provide fluid communication between an interior of said bowl and said second opening;
- and fastener means comprising a fastener engageable with said bowl member and said anchor means for releasably fastening said bowl means to said cartridge means.

A modular assembly for mounting to a fuel filter base comprising:
- cartridge means comprising filter means and housing means for housing said filter means, said housing means having an axis and a generally cylindrical shape and an end panel having an interior surface facing said filter means and an exterior surface and defining an axial opening extending axially along said axis;
- insert means disposed adjacent to said axial opening, said insert means engaging said interior surface and comprising a threaded surface extending axially along said axis interiorly of said housing means, said insert means further defining at least one aperture which communicates between the housing means interior and said axial opening;
- drain bowl means having an upper surface which engages said exterior surface in generally surface-to-surface relationship for forming a fluid-tight enclosure in fluid communication with said axial opening, said drain bowl means defining a central axis cavity extending axially along said axis and a shoulder;
- and
- fastener means for releasably securing said drain bowl means to said cartridge means by threadable engagement with said threaded surface, said fastener means comprising a bolt engageable against said shoulder and extending through said cavity.
