A ventilation valve and a tank device that includes such a ventilation valve, which fulfills both a roll-over function and an overflow protection function.

Venting valve

A valve device, a ventilation device having the valve device, and a motor vehicle tank device having the ventilation device. The connection between a valve inlet of the valve device and a tank outlet is to be opened and closed by the tank valve, and a connection between the inlet and the filler pipe outlet may be opened and closed by the filler pipe valve.

Valve device

A closure cover for tanks under internal pressure, with a cover body () which can be fixed in a tank neck by rotation, and with a cover () which is provided with a handle () and is operatively connected to the cover body (), and with a pressure control valve (). A coupling device (-) is arranged between the cover body () and the cover () and, during the positive pressure which prevails in the fuel tank during normal operation, releases the rotational connection between the cover body () and the cover () such that the fuel tank cannot be opened, and in that a pressure control valve () is provided which opens when the positive pressure prevailing during normal operation is exceeded.
