摘要

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to dunnage bags when the filling nozzles are removed against the pressure of adjacent filled dunning bags and are withdrawn.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. The novel valve operation provides for opening of the dunnage bag valve stem by means of air pressure rather than manual force heretofore required for moving the valve stem axially into open position and holding it there. The filling valve provides air for filling the dunnage bag at a suitable pressure for rapid filling without danger of bursting the bags. Also the valve is connected to fill the dunnage bag with substantially no loss of air thus making operating costs lower.
