Abstract
A vent valve for a buoyancy control device suitable for free-swimming divers, where the valve may be opened both manually and by a powered means, such as from a hydraulic or pneumatic pressure line, the hydraulic or pneumatic pressure being equalised with the ambient pressure when not activated.
Claims4
A device comprising a valve for venting gas from a bladder that is opened by pressure in a pneumatic or hydraulic hose connecting to at least three vent valves which are opened simultaneously by that pressure and when open vent gas from the bladder, and further comprising a manual means for opening the valve, such that pulling on a manual pull dump is not resisted by the piston that provides the pneumatic or hydraulic motion, and in which water ingress into the bladder is restricted by use of a one-way valve in series with the vented gas flow.
