Abstract : The patent relates to a diver's exhaust valve that is characterized by small size, smooth flow, and freedom from fouling by foreign matter. The valve comprises a valve member in the form of a spring and water biased diaphragm that separates the exhaust gas from the water which acts to close the valve. The disposition and configuration of flow passages produce continual flushing, while permitting adequate flow with a valve of smaller than usual size.
