Vehicular Fuel Tank Patents (Class 220/4.14)
  • Patent number: 10302053
    Abstract: A fuel tank structure comprising a fuel tank; a canister; a first pipe that joins together a holding portion of the fuel tank and the canister; a first shut-off valve provided at the first pipe; a filler pipe; a second pipe that joins together the filler pipe and the canister; a second shut-off valve provided at the second pipe; a pressure sensor that detects the pressure inside the holding portion; a fuel pump that feeds the fuel to an engine; and a control unit. The control unit opens the first shut-off valve during refueling such that evaporative fuel is permitted to move from the holding portion to the canister, and closes the first shut-off valve after refueling. The control unit opens the second shut-off valve when the pressure inside the holding portion detected by the pressure sensor drops below a predetermined pressure which is lower than the atmospheric pressure.

  • Patent number: 10086469
    Abstract: A method for welding together two workpieces. The method includes stamping, using a stamping system, a first workpiece comprising a material that creates vapor when melted, such as zinc. The first workpiece is stamped at a first preselected region to form a plurality of depressions in the first preselected region. The method further includes positioning the first preselected region adjacent a second preselected region of a second workpiece. After stamping and positioning as such, the method includes applying energy to at least one of the first preselected region and the second preselected region to melt material of the first and second workpieces to form a joint connecting together the first and second workpieces. Based on the configuration and arrangement created, any vapor formed by molten material vents from the joint being formed, between the depressions formed, and away from the first and second workpieces.

    Abstract: The invention relates to a method for the production of hollow bodies from thermoplastic plastic. The method comprises the extrusion of at least two sheet-like preforms consisting of thermoplastic plastic, the introduction of the preforms into a preferably multipart molding die with a molding cavity which at least partially defines the contour of the hollow body to be manufactured, and the shaping of the preforms inside the die, using a vacuum and/or gas pressure in the first heat of the material. The method is distinguished in that at least two preforms to be shaped into a hollow body and to be connected are extruded successively, that is to say sequentially, in time and are shaped simultaneously.
