  • Buoyancy control apparatus for divers
    Patent number: 4101998
    Abstract: A buoyancy control system for carrying by a diver has a fluid-tight reservoir comprised of a plurality of parallel longitudinally extending passageways, into which water and compressed gas can be selectively admitted through respective inlet valves to displace gas and water respectively in the reservoir through respective outlet valves. The relative amounts of water and gas in the reservoir can therefore be adjusted to provide a required degree of buoyancy for the diver.
