In a feed device ( 2 ) for a motor vehicle, a ventilation element ( 10 ) is arranged in a feed line ( 7 ) which is guided into an intermediate tank ( 8 ) arranged upstream of a surge chamber ( 3 ). The ventilation element ( 10 ) has an opening ( 11 ) which is closed when the fuel is flowing and is released if the flow fails. Drainage of the intermediate tank ( 8 ) by means of a siphon effect is therefore avoided.
1. A feed device for a motor vehicle having a surge chamber which is provided for arrangement in a fuel tank, having a filling device for the surge chamber, having a sucking jet pump which is arranged outside the surge chamber and is intended for feeding fuel via a feed line into the surge chamber or into an intermediate tank connected to the surge chamber, and having a section of the feed line which is guided vertically downward into the intermediate tank or the surge chamber, wherein the feed device comprises a ventilation element ( 10 ) is arranged in the region of the highest point of the feed line ( 7 ) that extends between the sucking jet pump and the surge chamber, and wherein the ventilation element has an upwardly open pipe ( 19 ), and in that the pipe ( 19 ) is longer than a column of fuel which can be produced by the pressure of the sucking jet pump ( 6 ) when the fuel tank ( 1 ) is virtually empty.
