Abstract
A dunnage bag valve and coupling arrangement comprises a valve stem having a spring loaded valve member which is movable to open a passage through the stem. A pair of circumferentially extending, diametrically opposed slots are formed on opposite sides of the stem. An axially extending opening is provided at one end of each slot for receiving a lug. A pair of lugs are formed on the inner cylindrical portion of a coupling so that the coupling can be pressed onto the stem and twisted, the lugs being introduced into the slot openings and then riding along the circumferential portions of the slots. An air hose is threaded to the coupling so that compressed air can be introduced through the valve stem into the dunnage bag. A fixed post inside the coupling opens the valve member when the coupling is engaged to the valve stem. To prevent rotation of the stem, teeth at the base of the stem engage teeth on the ring of a handle that is held while the coupling is pushed and twisted onto the valve stem.
