Abstract
A fuel filter and method of making same provides an in-tank filter having a novel fitting and seal construction. The filter includes a fabric body and a spacing structure disposed within the body to prevent collapse of the filter and accompanying reduction of or interference with fuel flow. The fitting comprises a first segment disposed outside the filter and incorporating a fuel line receiving aperture and a second, mating segment disposed within the filter. The filter segments are ultrasonically bonded to the fabric such that melting material from the segments flows into the interstices of the fabric and mechanically bonds and retains it within the segments of the fitting.
Claims15
A fuel filter comprising, in combination,
- a fabric body defining a fuel withdrawing aperture,
- a fuel line fitting for disposition in said fuel withdrawing aperture, said fitting including a first segment defining a through aperture, a second segment including a projection disposed within said through aperture and forming an interface with said first segment and a bead of material constituted at least partially of material from said second segment disposed adjacent said interface and engaging said fabric adjacent said fuel withdrawing aperture.
In a fuel filter having a fabric body defining a fuel withdrawing aperture, the improvement comprising, a fuel line fitting including a first fitting segment defining a through aperture and a second fitting segment having a projection disposed in said through aperture, said aperture of said first fitting segment and said projection of said second fitting segment defining a cavity for receiving a portion of fabric adjacent said fuel withdrawing aperture of said fabric body and material from said fitting segments dislodged during assembly whereby said portion of fabric is retained in said cavity by said dislodged material.
