Abstract:
A ventilation and/or a pressure-equalizing system for a fuel tank, in particular for a fuel tank of a motor vehicle, includes at least one aeration and/or de-aeration line leading into the fuel tank, via which the gases and/or vapors may be removed from or conducted into the fuel tank. A collection device for liquid fuel is coupled into the aeration and/or de-aeration line, the collection device including at least two chambers, of which one is used as a temporary storage device for liquid fuel and is connected to a return line into the fuel tank.
Abstract:
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).
Abstract:
A fuel lock as part of a venting arrangement for fuel tanks has to ensure that when the fuel tank is on its side, particularly after a lateral rotation of 270.degree., only a legally tolerated fuel quantity can flow out from the vent conduit. The fuel lock has an inlet chamber and an outlet chamber separated from the former by a partition and communicating with its chamber by a connecting conduit. The inlet chamber is connected to a surge tank of the fuel tank by an inlet conduit and the outlet chamber is connected to a vent conduit. In the inlet chamber, the inlet conduit and connecting conduit mouthpiece openings within the chamber and, in the outlet chamber, the connecting conduit and outlet conduit mouthpiece openings within the chamber are located relative to one another such that in the syphon conduit formed by these conduits and passing through the chambers, in each case a break point for the syphon effect is present within the chambers. The inlet conduit mouthpiece opening within the inlet chamber is located above the maximum fuel level in the tank installation attitude and in an attitude when the tank is on its side. The volume of the outlet chamber is larger than that of the inlet chamber and preferably corresponds to at least twice the volume of the outlet conduit.
Abstract:
A fuel tank having two tank spaces spaced from one another and connected to one another at a distance above their bottom. One tank space is equipped at its bottom with a retaining vessel having a closed shell. To assure that both tank spaces are reliably emptied, each tank space is equipped with a jet pump charged with fuel via a supply line. Both of the jet pumps, which are parallel or series connected to each other, deliver fuel to the retaining vessel.
Abstract:
A valve arrangement for ventilating and venting fuel tanks for motor vehicles which includes a vacuum valve, an excess pressure valve as well as a safety valve that interrupts the connection of the interior of the tank with the atmosphere beginning with a predetermined position of the valve arrangement deviating from the installed position. The safety valve includes a mass member displaceably arranged in the housing of the valve arrangement whose weight force is directed opposite the closing force of the excess pressure valve in the normal position of the valve arrangement and which beginning with a predetermined and subsequently continuing housing displacement acts increasingly on the valve closure member. It is assured thereby that the safety valve does not become operable already when the valve arrangement is not accurately installed or when the vehicle stands at an inclination but becomes effective only when it becomes actually necessary for safety reasons, for example, with a lateral roll-over of the vehicle caused by an accident, especially in the overturned position of a motor vehicle.
Abstract:
In an arrangement for supplying an internal combustion engine with fuel and a method for servicing and repairing the arrangement wherein a number of components, that is, a fuel reservoir, a fuel pumping unit, a fuel filter, a fuel level sensor and line elements are arranged in a fuel container and the container has an access opening formed in a wall thereof and sealingly closed by a cover, at least the fuel reservoir and at least one of the line elements are firmly installed in the fuel container and for servicing or replacement only the other components are removed through the access opening after being disconnected from their support mounts and associated connecting lines.
Abstract:
A device for ventilating and venting a fuel tank of a motor vehicle, has a ventilating device which compensates the pressure in the fuel tank, a separating container for separating fuel from a gas contained in the fuel tank. The operating ventilating device is connected to the separating container, the ventilating device and the separating container being arranged in the fuel tank.
Abstract:
A device for robotizable refuelling of a vehicle includes a docking component which can be installed on a filling tube of a fuel tank of the vehicle for receiving a pistol nozzle, in which the pistol nozzle can be locked, in axial and peripheral directions, and which has a central passage for a fill pipe of the pistol nozzle. The device contains a hollow cylindrical ring carrier element provided with a central passage fastened on an underside of the docking element. A locking ring provided with radially projecting bayonet arms is held against torsion but axially moveable on the ring carrier element. A compression spring is braced between the underside of the locking ring on the one hand and a connection of the ring carrier element. The device can be installed on the edge of the filling tube, which is provided with recesses for passage of bayonet arms of the locking ring at an inlet side to form a bayonet lock. In order to make secure refuelling possible in a simple manner, the ring carrier element carries a coupling ring arranged torsion fast on the filling tube lying on top of the locking ring. Stop structures corresponding to each other are defined on an upper side of the coupling ring and on the underside of the docking element so that the docking element can be fixed on the coupling ring.
Abstract:
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. The flexibly constructed feed lines are to be installed in the tank with an excess length which makes it possible to pull their line end pieces out of the tank openings and, outside the fuel tank, to connect them to the accumulation vessel and the distributor respectively.
Abstract:
A fuel tank, especially for motor vehicles, includes two shaped shells which include a shell bottom, shell walls and a continuous shell rim, the shell rims of the shaped shells being adapted to be welded together to thereby form a composite fuel tank structure. At least one of the bottoms of one of the shaped shells which forms one of the side walls of the composite fuel tank structure is provided with reinforcing ribs and an outwardly protruding bulge. Additionally, the bottom of the composite tank structure formed by a wall of one of the shaped shells includes a bulge. The bulges form flexurally soft deformation zone extending generally at right angles to the reinforcing ribs and generally parallel to a portion of the shell rim which extends generally parallel to the bottom of the composite tank for absorbing stresses.
