Abstract

A ventilation device for a fuel tank includes an antisurge element designed as a porous component manufactured from sintered plastic. The antisurge element prevents fuel which is sloshing around in the fuel tank from penetrating into an activated carbon filter of the ventilation device. The antisurge element is a fixed component that does not require any movable parts and is produced particularly cost-effectively.
