    摘要： 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.

    摘要： A fuel tank for vehicles is constructed so that any disturbing generation of noise in the fuel tank due to swashing fuel, particularly during acceleration and deceleration, is prevented. For this purpose wall sections of the fuel tank are equipped internally with a structured surface forming stabilization chambers.At the fuel-free regions of these walls sections, the swashing wave front of the fuel is dissolved over a large area, by the surface structure, into a plurality of wave sections which are distributed and diverted, whereby fuel movements which customarily generate swashing noises are effectively attenuated.
