ABSTRACT:
A hand held gun-type air injection device is provided for rapidly filling an inflatable dunnage bag with entrained ambient air to a predetermined maximum stabilized pressure level. The injection device is adapted for use specifically with a dunnage bag having a housing defining a chamber extending from an opening on the exterior of the bag to an opening in the interior of the bag. A tube assembly is provided for supplying pressurized gas or air adjacent the housing on the dunnage bag. A ring-like alignment frame is provided on one end of the tube for locating the tubing relative to the housing and in alignment with the chamber in the housing. The alignment frame is substantially open or apertured 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 ring-like alignment frame so that they are spaced from the walls of the housing chamber when the gun 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.
