This invention relates to tanks in which liquids are stored and from which said liquids are delivered, usually at atmospheric pressure. When such tanks are subject to angular displacement or to changes in acceleration as in an aircraft, it has been found difficult to maintain continuous liquids discharge therefrom, as the discharge outlet of such a tank may be partly or wholly uncovered from time to time, or the depth of the liquid above the outlet may vary widely.
It is the general object of my invention to provide a construction in a liquid storage tank which will effect continuous liquid discharge from the tank in any angular position of the tank or under substantial changes in acceleration or deceleration. To the attainment of this general object, I provide a plurality of separate discharge valves, together with means for opening each valve when submerged and when in a definite relation to the mass of liquid in the tank. I also provide a construction by which the liquid which passes out through all of the valves is discharged from the tank through a single discharge connection.
