ABSTRACT:
An inflation and deflation device especially adapted for use with dunnage air bags includes a cylindrical valve body possessing a first end mounted for relative rotation within a hollow interior cylindrical portion of a valve actuator. An internal spring biases a valve seat radially outwardly into engagement with an internal cylindrical side wall portion of the valve actuator. Rotation of the valve actuator selectively aligns air exhaust passages of the valve seat and the valve actuator to deflate an associated dunnage air bag. The valve body includes air passages connecting a compressed air source to the dunnage bag for selective inflation and to allow use of the compressed air source to provide a relatively high velocity air stream across an air passage connected to the dunnage bag to facilitate deflation of the bag by inducing a vacuum. One end portion of the valve body opposite the valve actuator includes an axially slidable coupling sleeve for selective engagement with a quick release valve of a dunnage air bag. A plurality of the inflation and deflation valves may be used in a manifold system to allow selective independent inflation and deflation of a plurality of dunnage air bags.
