Fuel tank system especially for motor vehicles and method for controlling and monitoring said system
Patent number: 6289947Abstract: The invention relates to a method for filling a fuel tank (2) with a filling conduit (4). The fuel flow entering the tank is directed by a through flow sensor (53) in order to control and monitor the filling process. A particularly suitable tank system (1) for implementation of said method comprises a fuel tank (2), a filling tube (3) surrounding a filling conduit (4) and discharging into said fuel tank, an adsorption filler (6) connected to the gas area (8) of the tank (2) and a through-flow sensor (53) which detects the flow of fuel in the filling tube (2).Type: GrantFiled: July 18, 2000Date of Patent: September 18, 2001Assignee: DaimlerChrysler AGInventors: Klaus J. Heimbrodt, Helmut Auernhammer, Thomas Theuer, Thomas Conrad, Ewald Duermeier, Bertold Ediger, Lothar Mauz, Dieter Scheurenbrand, Manfred Stotz, Manfred Weil -
Patent number: 5934306Abstract: In a fuel tank for motor vehicles including a tank vent with a venting valve, which automatically closes when the fuel in the tank reaches a predetermined level and when the vehicle is in an upside down position, the venting valve includes a vent closing member and a float structure engaging to the vent closing member and having a buoyancy, which is variable depending on the amount of fuel contained in the tank.Type: GrantFiled: November 18, 1997Date of Patent: August 10, 1999Assignee: Daimler-Benz A.G.Inventors: Mathieu Guillemenet, Roland Schirmer, Georg Georg, Manfred Weil, Hermann Horrer, Dieter Scheurenbrand, Manfred Stotz

Patent number: 5740842Abstract: A fuel tank arrangement for a motor vehicle. The arrangement includes a fuel tank containing fuel therein and having a gas space disposed above the fuel, and a venting device connected to the fuel tank. The venting device includes an activated charcoal filter and a venting conduit connecting the gas space to the activated charcoal filter for establishing gas communication therebetween. A stop valve is disposed in the venting conduit and is adapted to open gas communication between the gas space and the activated charcoal filter during refueling. Moreover, a fuel separator is disposed in the venting conduit for separating fuel from a gas flow through the venting conduit thereby yielding separated fuel.Type: GrantFiled: February 16, 1996Date of Patent: April 21, 1998Assignees: Walter Alfmeier GmbH + Co. Prazisions-Baugruppenelemente, Mercedes Benz AGInventors: Josef Maier, Dieter Simon, Wolfgang Liebhart, Thomas Theuer, Klaus Muller, Rolf Walter, Dieter Scheurenbrandt, Manfred Weil, Wolfgang Freiwald, Gerhard Kiermaier

Patent number: 5458373Abstract: The invention relates to a fuel tank having two tank parts which are connected to each other. Allocated to one tank part is an accumulation vessel and to the other tank part is a fuel distributor which is connected to a fuel return line. Two feed lines which convey fuel into the accumulation vessel are connected to the distributor. Integrated into one feed line is an ejector which is provided in the bottom region of the tank space having the distributor. Interposed in the other feed line is an ejector which is provided in the tank part having the accumulation vessel. For the purpose of being able to connect the feed lines to the fuel distributor and accumulation vessel quickly and easily, the fuel tank has a respective tank opening which can be tightly closed by them.Type: GrantFiled: December 16, 1993Date of Patent: October 17, 1995Assignee: Mercedes-Benz AGInventors: Dieter Scheurenbrand, Manfred Weil, Franz Gollner, deceased, Peter Weymann, Hermann Horrer

Patent number: 4536193Abstract: A reactor for gasifying solid fuels, particularly coal, comprises with the fixed bed of fuel at least one stirring arm, which is rotatable about a vertical axis and is approximately triangular in cross-section. The forward knife edge and the rear crushing edge of the stirring arm are provided with replaceable armoring. The armoring at the knife edge consists of a plurality of armoring elements (7), which are approximately V-shaped in cross-section and are arranged one beside the other so as to define an expansion joint. The armoring at the crushing edge consists also of a plurality of elements (10), which are mounted on the stirring arm so as to be movable at ambient temperature.Type: GrantFiled: September 27, 1983Date of Patent: August 20, 1985Assignee: Metallgesellschaft AktiengesellschaftInventors: Johannes Albrecht, Rudolf Jakobs, Osman Turna, Helmut Vierrath, Manfred Weil, Klaus Zapke
