Definitions
- the invention relates to a fuel tank with a ventilation system. Such fuel tanks are intended for use in motor vehicles.
- the ventilation system takes care of both ventilation and ventilation. While the ventilation is necessary to avoid a negative pressure in the fuel tank when the level decreases, the ventilation serves to avoid an excess pressure in the fuel tank. The overpressure can be used when refilling
- the free volume in the fuel tank is reduced.
- the fuel degasses at high temperatures, especially when hot, unused engine fuel is returned to the fuel tank.
- the ventilation system serves to operate the fuel tank safely.
- Such ventilation systems are arranged in the upper area of the fuel tank and have an opening in this area through which air into the fuel tank or gases from the fuel tank are directed. If the motor vehicle is in an inclined position for a long time, e.g. B. during parting, the vent is below the level of an almost full fuel tank Fuel level. As a result, the ventilation opening is closed and the fuel tank cannot be vented.
- a ventilation system with a plurality of openings for venting the fuel tank, the openings being arranged in different areas of the fuel tank. Under unfavorable circumstances, the openings of the ventilation system can also lie below the fuel level in this opening, so that ventilation is not guaranteed under all circumstances. In addition, the ventilation system with several openings requires a significantly higher effort in production and assembly.
- the present invention is therefore based on the object of creating a fuel tank which can be reliably vented under all circumstances, the venting being able to be carried out with as little effort as possible.
- the object is achieved with a fuel tank described at the outset, which has at least one chamber which is designed such that when the fuel tank is inclined, it is designed to hold a liquid volume above the liquid level of the fuel tank. Due to the fuel stored in the chamber, less fuel remains in the remaining fuel tank. As a result, the liquid level in the fuel tank drops when it is tilted, so that the ventilation opening, which, without the chamber, was below the liquid level, is now above the liquid level. This reliably ensures that the fuel tank is vented even when it is tilted.
- the fuel tank according to the invention allows the ventilation system to be simplified, so that ventilation lines which are complex to manufacture and difficult to assemble can be dispensed with. With the appropriate design of the chamber, the ventilation system may still be central have arranged opening, which significantly reduces the effort for ventilation.
- the chambers are designed in the shape of a scoop, the openings of the chambers pointing to the side walls of the fuel tank.
- the bottom of the chambers is designed such that it is horizontal in the normal position of the fuel tank or is slightly inclined downwards towards the opening of the chambers.
- the fuel can flow out of the chambers at any time in the normal position and is therefore available for delivery to the internal combustion engine. If the fuel tank is tilted, the fuel is retained in the corresponding chamber.
- at least one chamber is arranged on each side of the fuel tank. This ensures that fuel is retained in a chamber, regardless of which side the fuel tank is inclined to.
- the chambers also serve as damping elements for the liquid in the fuel tank.
- various guide elements can be arranged on the outside of the chambers, which serve to calm the liquid.
- the damping elements are advantageously molded onto the chambers. Such elements can be retrofitted if they can be connected to the corresponding chamber via a plug connection.
- the chambers can serve as holders for further components to be arranged inside the fuel tank.
- Lines, filters, suction jet pumps or other functional units can be fastened in the fuel tank by means of snap-in and plug-in connections arranged on the outside of the chambers.
- FIG. 4 the fuel tank according to FIG. 3 in an inclined position.
- the fuel tank 1 shown in Fig. 1 is arranged horizontally and is therefore in the normal position.
- the fuel tank 1 is without internals, for. B. fuel delivery unit, filter, pressure regulator, lines shown.
- the fuel tank 1 is almost filled with fuel 2, so that the liquid level A is in the upper region of the fuel tank 1. Above the liquid level A there is a volume of a fuel vapor / air mixture 3. A ventilation opening 4 belonging to a ventilation system (not shown further) is arranged centrally in the upper region of the fuel tank 1.
- the fuel tank 1 from FIG. 1 is arranged inclined to the left.
- the inclination of the fuel tank 1 means that the vent opening 4 is now below the liquid level A.
- the fuel vapor-air mixture 3 is enclosed by the fuel 2 in the upper right corner of the fuel tank 1. In this arrangement, the fuel tank 1 can no longer be vented.
- the fuel tank 1 has two chambers 5, 6, which are arranged on the upper boundary wall 8 of the fuel tank 1. Both chambers 5, 6 are closed the side walls 9, 10 of the fuel tank 1 open.
- the bottoms 7 of the chambers 5, 6 are designed to be inclined slightly downward, so that fuel 2 can flow from the chambers 5, 6 into the fuel tank 1 in this position of the fuel tank 1.
- Guide elements 11 are attached to the chambers 5, 6 for damping the movement of the fuel via latching and plug connections 12.
- Fig. 4 shows an inclined arrangement of the fuel tank 1. Due to the inclination of the fuel tank, the chamber 5, 6 are also inclined. The inclination is so slight that the slightly inclined bottom 7 of the chamber 6 is now inclined upwards, so that the chamber 6 retains a certain amount of fuel 2 in this position. Accordingly, less fuel remains in the fuel tank 1, so that the fuel level A 'is lower than that shown in FIG. 2. Due to the lower fuel level A ', the vent 4 is no longer closed by the fuel 2. The fuel tank 1 ⁇ st can thus be reliably vented despite the inclined arrangement.
