Arrangement for supplying an internal combustion engine with fuel

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.

Ventilation and/or pressure-equalizing system for a fuel tank

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.

Device for ventilating and venting a fuel tank

The invention relates to a method for filling a fuel tank (,) with a filling conduit (,). The fuel flow entering the tank is directed by a through flow sensor (,) in order to control and monitor the filling process. A particularly suitable tank system (,) for implementation of said method comprises a fuel tank (,), a filling tube (,) surrounding a filling conduit (,) and discharging into said fuel tank, an adsorption filler (,) connected to the gas area (,) of the tank (,) and a through-flow sensor (,) which detects the flow of fuel in the filling tube (,).

Fuel tank system especially for motor vehicles and method for controlling and monitoring said system

A closure for a filling tube of a motor vehicle with a swivel closure cover is arranged outside of a center opening of the filling tube in the tank and pivots around a swivel axis positioned in a plane perpendicular to the center axis of the opening. The closure is pre-stressed by a spring in a direction counter to the insertion movement of a filling pipe of a fuel supply nozzle. The closure is supported on a lower surrounding opening edge of the opening in the closed position to form a seal. An upstanding swivel facilitating element that can be contacted by the filling pipe is arranged on the closure. The closure cover is swiveled in a force-saving manner as a result of this swivel facilitating element. To achieve a safe and reliable closure operation of the closure cover for refuelling, and to reduce, as much as possible, an amount of force along the total insertion path of the filing tube, it is proposed to attach the swivel facilitating element to the upper side of the closure cover and to shape the element like a curved disc. The element has a guidance plane that faces the swivel axis. The highest geodetic position of the guidance plane, in the closed position, forms an end region farthest from the swivel axis of the course of the guidance plane that extends in the direction of the swivel axis. The swivel facilitating element is displaced from an edge of the closure cover in the direction of the closure cover center. An area section at the front of the filling pipe initially reaches the swivel facilitating element, during insertion into the filling tube, at an end region farthest from the swivel axis of the closure cover.

In an arrangement for limiting the fill level in a fuel tank having a filler neck with a tank inlet end, a valve flap is pivotally supported in the inlet end such that, in an open position, the valve flap is pivoted toward the fuel flow entering the tank during refueling and is connected, by way of a crank arm and a coupling rod to a float which is disposed in an essentially vertical guide tube. The coupling rod extends through the float and has spaced top and bottom stops providing for lost motion coupling between the float and the coupling rod whose weight is sufficient to keep the valve flap in an open position. When the fuel in the tank lifts the float and, after the float engages the top stop, lifts the coupling rod, closing movement of the valve flap is initiated which is then fully closed by the inflowing fuel utilizing the lost motion distance between the float and the bottom stop of the coupling rod.

Arrangement for limiting the fill level of a fuel tank

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.

Fuel tank for motor vehicles

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.

Device for and method of robotizable refuelling of a vehicle

A deventilating device for motor vehicles is disclosed. The deventilating device allows, in the fuel tank and connected system parts, a limited overpressure which, on the one hand, is safe and, on the other hand, affords the possibility of checking the tightness of the system by on-board means specific to the vehicle.

Motor vehicle fuel supply system with fuel tank deventilating device

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.

Fuel tank assembly

A blanking cover for the filler neck of a motor vehicle fuel tank has a grip protruding from the blanking cover body so as to ensure that reliable filler neck sealing is maintained in the case of a crash when a collision occurs between the grip and a body part. The grip can be released from the blanking cover body under the action of crash forces.

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.

Fuel lock for fuel tank venting arrangement

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.

An arrangement is disclosed for improving the seam strength of plastic containers produced by coextrusion blow-molding which are provided with a diffusion barrier layer incompatible with the base material. To improve the seam strength, the same is therefore designed as a web seam which is folded in labyrinthal shape and the folds of which are welded to each other. The length of the web seam in the unfolded state is equivalent to at least three times the thickness of the coextrudate and the web seam is folded at least doubly.

Multi-layered plastic container produced by coextrusion blow-molding

A valve device is disclosed for an aeration and air evacuation pipe leading away from a motor fuel tank. In a known valve device for aerating and evacuating air from a motor fuel tank, a positive pressure valve is provided, the closing force of which is generated by a compression spring which is braced against its valve element. This closing force generally corresponds to the positive pressure value of a water column of 300 to 400 mm. Such a positive pressure valve is therefore unsuitable for aeration and air evacuation devices in which the required positive pressure value is very low, only approximately 80 mm WG for example, for safety and functional considerations, and correct functioning of the valve element of the positive pressure valve is required to be ensured even at low temperatures. The positive pressure valve of the novel valve device fulfills these requirements, in that its valve seat is provided on a downward sloping end face of a duct, and the valve element is a weight component which rests upon the valve seat exclusively by the effect of gravity. By coordinating the characteristics of duct cross-sectional area and weight of the valve element, any desired closing force can be determined to close tolerances, while it is impossible for condensate to accumulate under the valve element, and therefore for the latter to freeze fast.
