ABSTRACT:
An apparatus for ventilating a liquid tank in which ventilation pipes are arranged so that the orifice of at least one ventilation pipe is above the liquid level and the orifice of at least one ventilation pipe is below the liquid level. The remaining ends of the ventilation pipes connected to separate chambers which are sealed off from the tank interior. These chambers are associated with a rotary slide valve which can be controlled by the flight attitude. The control slots of this valve are staggered (offset) in such a way that with simultaneous free flow passage via at least one ventilation pipe located above the liquid level, flow passage via at least one ventilation pipe located below the liquid level is blocked.
