Patents by Inventor Markus Distelhoff

Markus Distelhoff has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Fuel tank
    Patent number: 6591866
    Abstract: A fuel tank for a motor vehicle is described and has a collector tank disposed in its interior for extracting air from it. The collector tank is connected to a pressure-equalizing device that is disposed outside the fuel tank and has an activated carbon filter. Fuel penetrating into the collector tank is extracted by suction by a pump configured as a suction jet pump. As a result, the fuel tank has particularly low levels of fuel emission.
    Type: Grant

  • Ventilation device for a fuel tank
    Patent number: 6527008
    Abstract: The invention relates to a ventilation device for fuel tanks, wherein the ventilation device comprises a compensator reservoir arranged in the interior of the fuel tank and at least two ventilation lines. The ventilation lines run from below the upper tank wall to the compensator reservoir and extend in the latter toward an opposite tank wall. The apparatus according to the invention is particularly well suited under all static and dynamic stresses for ventilating fuel tanks.

  • Fuel tank
    Patent number: 6491180
    Abstract: A fuel tank for a motor vehicle comprising a wall composed of two shells arranged one above the other. The outer shell of the wall preferably has an inlet orifice and an outlet orifice. A filter element is arranged in front of the outlet orifice. Scavenging air from the inlet orifice thereby passes first into a gap between the shells and subsequently to a filter element. As a result, fuel vapors can no longer diffuse through the wall and pollute the environment.

  • Venting device
    Publication number: 20020108604
    Abstract: A venting device for a fuel tank of a motor vehicle includes a compressor for sucking gases out of the fuel tank and delivering them into a pressure vessel. When the motor vehicle is stationary, the pressure inside the fuel tank can be regulated by suitably controlling of the compressor. Gases that have collected in the pressure vessel are fed to an internal-combustion engine of the motor vehicle.

  • Fuel tank for a motor vehicle
    Patent number: 6409040
    Abstract: A fuel tank for a motor vehicle, having a wall (3) which is manufactured from plastic, in particular by injection molding, is provided on its inside with a permeation barrier (4). The permeation barrier (4) is manufactured from a material which is virtually impenetrable for fuel vapors. The permeation barrier (4) is composed of shell parts (5, 6) which are welded to one another.

  • Method of producing a plastic component and fuel tank for a motor vehicle
    Patent number: 6395215
    Abstract: In a method of producing a fuel tank from plastic, a heating element is located between two shell parts to be welded to one another. When the shell parts are pressed together, the heating element melts into the plastic and produces a weld that provides a fuel-resistant seal. The fuel tank subsequently has a particularly exact shape.

  • Device for supplying an internal combustion engine of a motor vehicle with fuel
    Patent number: 6250328
    Abstract: A device for supplying an internal combustion engine (1) of a motor vehicle with fuel has a return line (4) which is passed into a fuel tank (2) and has a wall made of a material of high thermal conductivity. The return line (4) is arranged within a ventilation duct (5). Cooling air is conveyed through the ventilation duct (5) to the return line (4). This is a simple means of limiting the maximum temperature of the fuel in the fuel tank (2).
