Abstract
A demand regulator for use in underwater breathing apparatus employs a vane member dividing the mouthpiece tube into two adjacent air passageways. An interior end of the vane is configured as an air deflector for conducting pressurized air out of the mouthpiece tube substantially through only one of the passageways. The opposite end of the vane is provided with an inclined tab for applying back pressure to the air exiting from the mouthpiece tube, whereby the venturi action of the exiting pressurized air, and consequent free flow tendency of the regulator, are controlled.
