ABSTRACT:
A topping and dumping valve is provided for inflating and deflating inflatable structures, such as life rafts and military assault boats. The valve includes a first cylindrical body mounted in the inflatable structure, and a second cylindrical body threadably mounted in the first body for movement between first and second positions. In the first position, air is directed through a passageway in the second body and through inflation ports in the first body so as to move a normally closed flapper seal out of sealing engagement with the inflation ports, thereby inflating the buoyancy chamber of the structure. When the second body is in the second position, deflation ports in the first body allow air from the buoyancy chamber to escape through the deflation ports and the passageway in the second body to the atmosphere. A protective cap is provided for closing the passageway in the second body when the valve is not being used during inflation and deflation of the inflatable structure.
