ABSTRACT:
An arrangement for limiting the filling of tanks and for aeration and ventilation of tanks in which a portion of the tank volume acts as a pressure-compensation space for temperature changes, has an aeration and ventilation arrangement opening into the aeratable and ventable filler neck, said arrangement having a filling vent which determines the maximum allowable liquid level and an operating vent to take over aeration and ventilation of the pressure-compensation space with a sealing arrangement, such that the operating vent is sealed off by the action of a spring when the tank cap is removed, and when the tank cap is attached, it is thereby opened against the spring pressure. Operating ventilation is controlled by a valve integrated into the aeration and ventilation line which valve can be actuated against spring resistance by a plunger rod. The valve is placed in the filler neck in such a way that the plunger rod runs parallel or substantially parallel to the side of the filler neck within the same filler neck, and its free end projects from the filler neck when the tank cap is removed.
