ABSTRACT:
A cargo or dunnage air bag inflation and deflation system comprises an inflation-deflation valve member, a cap-type plug member, and an air gun implement having a fill nozzle and an exhaust nozzle mounted upon opposite ends thereof for respective connection to the valve member in order to perform inflation and deflation operations. The valve member comprises a flapper or check valve element pivotally mounted upon the valve member so as to permit inflation or deflation of the cargo or dunnage air bag when the flapper or check valve element is moved away from its valve seat, and to substantially maintain the cargo or dunnage air bag in its inflated state when the flappper or check valve element is effectively seated upon its valve seat. The cap-type plug member is removably mounted upon the inflation-deflation valve member so as to effectively close and seal the valve assembly when the cap-type plug member is mounted upon the valve member, and effectively uncovers the valve member when the cap-type plug member is dismounted from the valve member so as to permit the air gun implement to be operatively connected to the air valve member in order to perform an inflation or deflation operation.
