Abstract
A connection arrangement for a tube is provided. The invention connection arrangement comprises a device configured to communicate fluid from an inlet to an outlet wherein the device includes at least one fitting having a plurality of protrusions extending therefrom. The connection arrangement further includes a polymer coated tube comprising aluminum material coupled with the fitting of the device, and the tube is configured to communicate matter with the device. The tube has an outer surface, an inner surface, at least one open end, a center passageway, a longitudinal axis extending through the center passageway, and a polymer coating. When mated together, the protrusions of the fitting create a tight seal and connection between the fitting and the tube.
Claims27
A connection arrangement for a tube, comprising:
- a device configured to communicate fluid from an inlet to an outlet, said outlet including at least one fitting having a plurality of protrusions extending therefrom;
- and
- a polymer coated tube comprising aluminum material coupled with said fitting of said device, said tube having an outer surface, an inner surface, at least one open end, a center passageway, and a longitudinal axis extending through said center passageway;
- wherein said tube is configured to communicate said fluid, and said protrusions of said fitting are configured to create a tight seal and connection between said fitting and said tube.
A fuel delivery system, comprising:
- first and second fuel rails wherein at least one fuel rail includes an inlet for receiving pressurized fuel, and each of said fuel rails having an orifice to allow for fluid communications between said fuel rails;
- and
- a polymer coated crossover tube comprising aluminum material configured to communicate fuel between said fuel rails, said tube having a connection at opposite ends with said respective fuel rails, said tube including an outer surface, an inner surface, a center passageway and a longitudinal axis extending therethrough;
- wherein at least one of said first and second fuel rails includes a fitting having a plurality of protrusions protruding outwardly therefrom, said protrusions penetrating creating a tight seal and connection between said tube and said fitting.
A method of connecting a polymer coated tube to a device, comprising the steps of:
- providing a tube comprising aluminum material having an outer surface, an inner surface, at least one open end, a polymer coating, and a center passageway, said tube further including a longitudinal axis extending through the center passageway;
- providing a device configured to communicate fluid from an inlet to an outlet, said outlet including at least one fitting for connecting said device to said at least one open end of said tube so as to communicate said fluid between said tube and said device, said fitting including a plurality of protrusions protruding therefrom;
- coupling said tube with said fitting of said device so as to cause said protrusions to create a tight seal and connection between said tube and said fitting.
