ABSTRACT:
A hollow housing is mounted in a wall of the dunnage bag and defines a chamber having an exterior opening in a portion of the housing on the exterior of the bag, and an interior opening in a portion of the housing communicating with the interior of the bag. A tube is provided for supplying pressurized gas or air adjacent the housing on the dunnage bag and has an alignment frame on one end for locating the tube relative to the housing and in alignment with the chamber in the housing. The alignment frame is substantially open to permit free flow of ambient air past exterior portions of the tube into the chamber. One or more orifices are located on a portion of the tube to allow discharge of jets of high pressure gas or air therethrough. The orifices are arranged and located in the tube with respect to the alignment frame so that they are spaced from the walls of the housing chamber when the tube is engaged with the housing, whereby, as the jets of pressurized gas are discharged into the chamber, ambient air is aspirated from between the orifices and the chamber through the chamber into the dunnage bag.
