Inflation/deflation adaptor assembly for inflating and deflating inflatable cargo dunnage bags

An inflator/deflator mechanism for use in conjunction with an inflation valve fixedly secured upon an inflatable member to be inflated, comprising:

• a housing to be mounted upon an inflation valve;
• an axial bore defined within said housing;
• a compressed air inlet port defined upon a first side wall portion of said housing for permitting compressed air to enter said housing from a source of compressed air;
• a compressed air outlet port defined upon a second side wall portion of said housing so as to be fluidically connectable to said compressed air inlet port defined upon said first side wall portion of said housing for permitting compressed air, entering said housing from the source of compressed air and through said compressed air inlet port, to exit said housing through said compressed air outlet port as a result of the compressed air traversing said axial bore defined within said housing;
• and
• a control rod, rotatably disposed within said axial bore of said housing between first and second angularly spaced positions, and having fluid passageways defined therein for permitting compressed air to be conducted from said compressed air inlet port of said housing, through said control rod, and toward the inflation valve, when said control rod is disposed at said first position, so as to therefore inflate the inflatable member, and for inducing the air, disposed within the inflatable member, to be evacuated from the inflatable member, through said control rod, and out through said compressed air outlet port of said housing, as a result of compressed air flowing from said compressed air inlet port defined within said first side wall portion of said housing, across said axial bore defined within said housing, through said control rod, and out through said compressed air exit port defined within said second side wall portion of said housing, when said control rod means is disposed at said second position, so as to therefore deflate the inflatable member.
