ABSTRACT:
A gas control valve (802) has an inlet needle jet (812) and an outlet (816), the communication between which is controlled by a valve member (808) carried by a rod (807) connected to a diaphragm (804) which divides a chamber (806), open to ambient pressure, from a chamber (805) which has an inlet connected to a buoyancy chamber (100) of buoyancy apparatus in which the valve is incorporated. The inlet (816) is also connected to the buoyancy chamber (100). By the inclusion of an ascent sensing control valve (801) sensing to trigger a venting valve (106), the buoyancy control apparatus is capable of producing hovering in water.
