  • Publication number: 20080169364
    Abstract: The present invention is directed towards a vehicular fuel delivery system. In accordance with one exemplary embodiment of the invention, the fuel delivery system includes a fuel rail having at least one feed, and at least one fuel injector assembly comprising a fuel injector and an outer housing. In accordance with this embodiment of the invention, the fuel injector assembly is permanently affixed to the fuel rail so that the feed of the fuel rail is in fluid communication with an inlet of the fuel injector, wherein at least a portion of the fuel injector assembly is configured to be replaceable.

  • Publication number: 20080028592
    Abstract: A method of coupling tubular bodies is provided, particularly for use in fluid handling systems requiring a fluid-tight, pressurized joint. One tubular body is made from a polymer. The other tubular body is formed as a bare metallic body (e.g., aluminum tubing). The tubular bodies are positioned relative to one another (e.g., the metallic tubular body may be inserted within the polymeric tubular body). The tubular bodies are then joined together by generating heat (e.g., through induction welding) to cause heat transfer from the metallic tubular body to the polymeric tubular body thereby resulting in deformation of the polymeric tubular body and bonding of the polymeric tubular body to the metallic tubular body.

  • Patent number: 7263975
    Abstract: An improved fuel rail for delivering fuel to a fuel injector for an internal combustion engine is provided that reduces the weight of the fuel injection system, greatly reduces manufacturing costs by eliminating expensive manufacturing methods, such as brazing, high heat welding, post plating, blow molding, and extrusion, and enhances low-cost, low-energy methods for attachment of fuel system components to the fuel rail. The improved fuel rail includes an tubular body defining a fluid chamber and having an inlet through which fuel enters the fluid chamber and a fuel injector port in fluid communication with the fluid chamber. The port is configured to receive the fuel injector. The tubular body is formed as a laminate having an inner metallic layer and an outer polymeric layer. The inner metallic layer may comprise aluminum and the outer polymeric layer may comprise nylon. Plastic or metal components can be attached to the laminated tubular body while providing a fluid tight, pressurized joint.

  • Patent number: 6733047
    Abstract: A quick connector apparatus and method of forming same includes a retainer element having a first end portion spin welded to an inner surface of a bore formed in an end portion of a first conduit after a sealing element has been mounted in the end portion of the first conduit. The retainer element includes a movable latch member projecting from the second end which is engagable with an enlarged annular flange on the second conduit to releasably interconnect the second conduit and the retainer; while at the same time providing sealing between the second conduit and the first conduit via engagement between the internally mounted sealing element and the retainer element.

  • Publication number: 20030197373
    Abstract: A fluid quick connector includes a connector housing having a through bore adapted to receive a tubular endform. A retainer is transversely mountable through the connector housing into engagement with the endform. A retention clip having at least one angled end projection is carried on the retainer for movement to a final latched position with the endform while enabling the endform to be inserted into the connector housing without substantial contact with the retention clip. The retention clip is in the form of a planar body having at least one angled projection extending therefrom. Preferably, a plurality of angled projections are formed on the retention clip. The retention clip is fixedly secured to the retainer or insert molded in the retainer for movement concurrent with movement of the retainer relative to the connector housing.

  • Patent number: 6199916
    Abstract: A joint between a fluid connector body and a plastic tube is formed at least in part by spin welding, wherein the portion of the connector which is configured to receive the tube defines inner and outer surfaces which engage the inner and outer surfaces of the mating tube to create redundant circumferentially continuous seals between the fluid passageway and the outside environment. The use of multi-layer co-extruded plastic tubing having intermediate or bonding layers is particularly advantageous inasmuch as separate inner and outer seals are established between the connector housing and the inner and outer tubing layers, respectively, to ensure that neither system fluids nor foreign contaminants are exposed to the intermediate tube layers, thereby preventing capillary adsorption or delamination.
