Abstract
A method is disclosed for rapidly filling an inflatable dunnage bag with entrained ambient air to a predetermined maximum stabilized pressure level. A dunnage bag is provided with a housing defining a chamber extending from an opening on the exterior of the bag to an opening in the interior of the bag. In the preferred form of the method, a supply of pressurized gas or air is brought adjacent to the housing in the dunnage bag and is located relative to the housing and in alignment with the chamber to permit flow of ambient air into the chamber. One or more jets of high pressure gas or air are discharged into the chamber substantially parallel to, and spaced from, the walls of the chamber, whereby, ambient air is entrained through the chamber to the interior of the bag until an equilibrium is reached where the mass flow rate of the air entering the bag equals the mass flow rate of the air flowing back out of the bag in response to the internal pressure.
