ABSTRACT:
An emergency ascent system to be used by a diver in conjunction with a pressurized breathing system. Responsive to a valve operated by the diver, air pressure is applied to a first end of a cylinder, and a piston therein is moved from the first end to a second end, ejecting a counter buoyancy weight, and causing the applied air pressure to be valved to an air bag, which is inflated thereby to effect the ascent of the diver.
