Valve assemblies for a dunnage or cargo air bags, and related methods of use

摘要

Generally disclosed is an exemplary dunnage bag valve assembly that may be used to inflate a dunnage bag to capacity or deflate a dunage bag while minimizing the impact of fighting back pressure during deflation. In one embodiment the valve assembly comprises: a tubiform body having a flange disposed therearound; an internal support bar; a flapper coupled to the support bar along the midsection of the flapper, wherein the flapper closes the tubiform of the tubiform body; a lever with a fulcrum on the support bar, wherein operating of the lever on the fulcrum bends or folds the flapper along its midsection for opening the tubiform of the tubiform body during deflation of an air bag.
