Abstract
An underwater exhaust system includes an exhaust valve with a valve cover operatively coupled thereto. The valve cover is adapted to create an exhaled air pocket on the water interface side of the valve. The exhaled air pocket allows the valve to operate under reduced water resistance. The valve cover includes at least one water inlet passage and at least one exhaust gas opening.
