Abstract
A multipart fuel filter element includes a cartridge body having a plurality of through bores radially offset with respect to a centerline. An inlet end cap adjacent a first cartridge face includes an inlet aperture centrally aligned with the centerline and a plurality of distribution apertures aligned with and directing fuel to the plurality of through bores. An outlet end cap adjacent a second cartridge face includes an outlet aperture also aligned with the centerline and a plurality of reception aperture that are aligned with the through bores to receive fuel.
Claims21
A fuel filter cartridge comprising:
- a cartridge body extending between a first cartridge face and a second cartridge face, the cartridge body including a plurality of through bores disposed between the first cartridge face and the second cartridge face;
- a plurality of filtration rods accommodated one each in the plurality of through bores;
- an inlet end cap adjacent the first cartridge face, the inlet end cap having an inlet aperture adapted to interface with an inlet hose fitting, and a plurality of distribution apertures aligned with the plurality of through bores at the first cartridge face;
- and
- an outlet end cap adjacent the second cartridge face, the outlet end cap including a plurality of reception apertures and an outlet aperture, the plurality of reception apertures being aligned with the plurality of through bores at the second cartridge face and the outlet aperture being adapted to interface with an outlet hose fitting.
A fuel filter cartridge comprising:
- a first end and a second end opposite the first end;
- a cartridge body having a first cartridge face and a second cartridge face, the cartridge body including a plurality of bores disposed into the first cartridge face toward the second cartridge face;
- a plurality of filtration rods accommodated one each in the plurality of bores;
- an end cap adjacent the first cartridge face, the end cap including a first central aperture at the first end and a plurality of communication apertures, the communication apertures aligned and communicating with the plurality of bores at the first cartridge face;
- and
- a second central aperture at the second end, the second central aperture aligned with a centerline of the fuel filter cartridge and in fluid communication with the plurality of bores of the cartridge body.
A fuel filter cartridge comprising:
- a cartridge body including a plurality of through bores radially offset with respect to a cartridge centerline of the fuel filter cartridge, the plurality of through bores exposed at a first cartridge face and at a second cartridge face;
- an inlet end cap including an inlet aperture aligned with the centerline and a plurality of distribution channels angularly offset with respect to the centerline and establishing fluid communication between the inlet aperture and the plurality of through bores at the first cartridge face;
- and
- an outer end cap including an outlet aperture aligned with the centerline and a plurality of reception channels angularly offset with respect to the centerline and establishing fluid communication between the outlet aperture and the plurality of through bores at the second cartridge face.
