<p>The device has pipes extending from the tank for operational and filling ventilation. The pipes (10,11) have neighboring or common walls in at least one area outside the fuel tank (1), or engage around each other. The outer walls of the pipes are mainly cylindrical. The pipe (11) for filling ventilation has a larger diameter than the pipe (10) for operational ventilation, which is closed by a valve (12). A compensation vessel (5,6) located in one pipe has a common wall with a vessel in the other pipe. Both vessels are integrated in the tank.</p> |
