Abstract

A valve device for a fuel tank of a motor vehicle includes, for example, a housing having a tank connection for connecting the valve device to a vent line going to or coming from the fuel tank, and a filter connection for connecting the valve device to a vent line going to or coming from an activated charcoal filter. The tank connection and the filter connection are fluidically connected to one another inside the housing through a vent duct. A valve is arranged inside the housing for opening and at least partially closing the vent duct, wherein the valve has a valve element that is movably mounted between an opening position and a closed position inside the housing along a longitudinal axis of the housing. An actuating element is accessible from outside the valve device, which is movably mounted along the longitudinal axis inside the housing and motion-coupled in such a way with the valve element that a movement of the actuating element in a closing direction moves the valve element in closing direction. A valve element return element is configured to move the valve element in an opening direction, and arranged outside the vent duct, between the valve element and the housing.
