Fuel tank

Abstract

The invention relates to a fuel tank ( 1 ) for a motor vehicle, the upper section of which is provided with at least one opening ( 4 ) of a ventilation system. According to the invention, at least one chamber ( 5, 6 ) for receiving fuel ( 2 ) when the fuel tank ( 1 ) is in an inclined position, is configured in the upper section ( 8 ) of the fuel tank ( 1 ).

1 . A fuel tank for a motor vehicle, in the upper region of which at least one opening of a ventilation system and at least one chamber are arranged, characterized in that at least one chamber ( 5 ,  6 ) is designed in such a way that, in the event of a deviation of the fuel tank ( 1 ) from a horizontal position into an inclined position, it holds a volume of fuel ( 2 ) and separates said volume of fuel from the remaining volume of fuel for the duration of the inclination.  
   
   
       2 . The fuel tank as claimed in  claim 1 , characterized in that the chambers ( 5 ,  6 ) are open toward the side walls ( 9 ,  10 ) of the fuel tank ( 1 ).  
   
   
       3 . The fuel tank as claimed in claims  1  or  2 , characterized in that the chambers ( 5 ,  6 ) have a base ( 7 ) which is designed in such a way that, in the horizontal position of the fuel tank ( 1 ), the base is horizontal or inclined slightly downward toward the side walls ( 9 ,  10 ) of the fuel tank ( 1 ).  
   
   
       4 . The fuel tank as claimed in  claim 2 , characterized in that each side wall ( 9 ,  10 ) has a respective chamber ( 5 ,  6 ) oriented toward it.  
   
   
       5 . The fuel tank as claimed in  claim 1 , characterized in that guide elements ( 11 ) are arranged on the chambers ( 5 ,  6 ).  
   
   
       6 . The fuel tank as claimed in  claim 5 , characterized in that the guide elements ( 11 ) are integrally formed on the chambers ( 5 ,  6 ) or connected to the chambers ( 5 ,  6 ) by means of a locking and plug connection ( 12 ).  
   
   
       7 . The fuel tank as claimed in  claim 2 , characterized in that the chambers ( 5 ,  6 ) have receptacles for fastening components, in particular lines, filters and pumps to them.
