Abstract

A valve suitable for a fuel tank may include a valve housing having a housing part, and a float configured for closing a vent opening, the float being movably arranged inside the valve housing along a middle longitudinal axis running in an axial direction upward or downward. A lower section of the float faces away from the vent opening and faces toward the housing part of the valve housing. At least one spring element is at least partially arranged in or on the housing part and/or is at least partially formed by the housing part. The spring element contacts the float at least when the float moves downward in the valve housing.
