Abstract
According to the invention, in the case of a multifunctional valve for a vehicle container, comprising a first opening which can be closed by means of a first closing body as a function of the filling level of the container and is intended for ventilating the tank as it is being filled, a second opening which can be closed by means of a second closing body and is intended for ventilating the tank during operation, the two closing bodies automatically going into their closing position if the vehicle takes up an excess sloping position or undergoes a roll-over action, the two closing bodies (13, 18) can be brought into the closing position by a respectively assigned first or second float body (11, 17) which are of lower density than the medium in the container, and in the event of a roll-over action, a mechanical device (ball 19) acts upon the two float bodies (11, 17) to counter their buoyancy and keep the closing bodies (13, 18) in the closing position.
