Abstract
The inhalation tube of a pressure regulator is divided by means of a baffle curved at its inner end adjacent the side wall of the chamber so that when the regulator is in the water with the mouthpiece open, water is channeled into the regulator chamber through the inhalation tube along one side of the baffle and air flows out through the tube along the other side of the baffle.
