Abstract: Problems of filling dunnage bags for cushioning loads in transit in trailers, railroad cars, and the like, with air are resolved by this improved air filling bag valve and nozzle. In several respects the valves are superior in operation, wasting less air and filling time, and are less tiring for operators to use. For example, this nozzle simply slides laterally into place on the dunnage bag valve stem and locks itself there for hands off filling without manual pressure to press the nozzle axially against dunnage bag valve stems to open them, which is fatiguing with arms outstretched in the crowded spaces available. Damage is reduced that may result to dunnage bags when the filling nozzles are removed against the pressure of adjacent filled dunning bags and are withdrawn. These nozzles are simply pulled out laterally by the attached hose.
