Abstract
A closing arrangement for a vent line of a fuel tank includes a housing with an inlet and an outlet as well as a closing device which is actuated as a function of the position of the vehicle. The closing device includes a mass part and a closing part, the latter closing a connecting opening in the housing when the vehicle is in an inclined position. In order to provide a closing arrangement that functions well even in the case of an intensified gasification of the fuel, two chambers located above one another are provided inside the housing and are connected with one another via the connecting opening, in which case the mass part is arranged in one chamber and the closing part is arranged in the other chamber, and a connecting element extends between the mass part and the closing part that penetrates the outlet opening and, in sections, projects into both chambers.
