Abstract:

An assembly for generating buoyancy for an attached self-propelled body for movement from a release position beneath a water surface to a second position closer to the water surface includes an air bag connected to the body, a differential pressure relief valve in communication with the air bag, and a gas source in communication with the air bag. The source provides gas to the air bag to inflate the air bag to lift the body toward the second position, and the pressure relief valve is operative to maintain a selected pressure differential in the air bag relative to outside water pressure. 2 figures
