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.

1. A multifunctional valve for a vehicle fuel tank comprising:(1) structure providing a first opening to effect primary ventilation of the tank during filling thereof; (2) a first float structure having, (a) a first closing body for effecting closing of the first opening; (b) a second opening extending through the first closing body providing throttled, secondary ventilation of the tank after the first opening is closed; (c) a float body portion of a first density which is less than the density of the fuel in the tank dependent from the first closing body and defining a hollow cylindrical interior; (3) a second float structure mounted for rectilinear movement within the hollow cylindrical interior of the first float structure, the second float structure having, (a) a second closing body for effecting closing of the second opening in the first closing body, (b) a float body portion of a second density which is (i) less than the density of the fuel in the tank and (ii) greater than the density of the first body float portion; and (4) a ball of weight sufficient to retain both the first and second closing bodies in the closing position in the event of vehicle rollover.
