  • Patent number: 6957658
    Abstract: In a fuel tank installation including a fuel tank with an expansion volume, a filler neck connected to the fuel tank below a maximum fuel level of the tank for refueling the tank, a fill vent line for venting the fuel tank during refueling and an operating vent line for venting an expansion volume of the tank, the operating vent line extends within the fuel tank from the expansion volume of the fuel tank to a central penetration location and, at the central penetration location, through the wall of the tank together with the fill vent line.
    Type: Grant

  • Patent number: 6918416
    Abstract: In a fuel tank installation including a fuel tank with an expansion volume, a filler neck connected to the fuel tank for refueling, a fill vent line for venting the fuel tank during refueling and an operating vent line for venting the expansion volume of the tank, electrically operable valve means for blocking the operating vent line are arranged in a penetration area of the fuel tank where the operating vent line extends through the fuel tank.

  • Patent number: 6863084
    Abstract: A fuel tank, in particular for a motor vehicle having a tank venting system, comprises a sucking jet pump which feeds fuel into a sucking-jet-pump feedline which fills a storage pot arranged in the tank. The sucking jet pump has a driving nozzle. A line leads from the region of the tank roof into a negative pressure region of the sucking jet pump.

  • Publication number: 20010040375
    Abstract: A flexible line element, particularly for exhaust pipes of internal combustion engines of motor vehicles, is characterized in that it has at least two interconnected, metal bellows provided with cylindrical joining ends and at least one of the bellows is helically corrugated. This and/or the bellows are telescoped and two bellows are connected at only one of their joining ends. A line element constructed in this way is on the one hand torsion-soft, so that it does not transfer any torsional stresses to adjacent components, and on the other is also stable in the case of high torsional stresses.

  • Patent number: 6315332
    Abstract: The invention is a flexible line element, particularly for exhaust pipes of internal combustion engines of motor vehicles. At least two interconnected, metal bellows are provided with cylindrical joining ends and at least one of the bellows may be helically corrugated. The bellows may be telescoped. The two bellows, whether in line or telescoped, are connected at only one of their joining ends. A line element of the invention is on the one hand torsion-soft to not transfer any torsional stresses to adjacent components, and on the other is also stable in the case of high torsional stresses.
