Abstract
A vent arrangement for fuel tanks of motor vehicles which includes an expansion tank, with which is connected an expansion line extending horizontally in the vehicle transverse direction which includes two line sections extending in mutually opposite directions, of which one terminates in the atmosphere and prevents an outflow of fuel in the turned-over head position of the fuel tank. In order that also in special positions of the fuel tank conditioned on accidents, fuel cannot flow to the outside in non-acceptable quantities by way of the expansion line, an enlargement is provided in the line section terminating in the atmosphere in proximity of the tank side wall from which it extends away; fuel flowing out of the expansion line in a tank side position retaining the enlargement above the plane of the fuel level sucks gas out of the enlargement while the volume of the enlargement is so selected that the gas quantity present in the enlargement suffices with fuel flowing out to the outside up to the interruption of a siphoning action produced inside of the enlargement on the fuel.
