Abstract
Bulk silo with an outlet chamber, from whose upper area a generally open ventilation line runs which is provided with a closing valve for protection against flooding. The closing valve is constructed as a float valve. In order that this closing valve does not become inoperable due to clogging or being inundated with bulk material, its float cage is provided in the area below the float with an aeration device which can be made closed like a plate in order to protect the valve from the direct surge of the material.
