ABSTRACT:
A regulator for an underwater breathing apparatus includes a box-shaped body enclosing the air flow-regulating device, a tube connected to the box-shaped body supporting a mouthpiece, an air inlet duct connected to the box-shaped body through an inlet valve operated by the regulating device, and a deflector element. The deflector is fitted so that it swings inside the regulator between a position in which the deflector partially shuts off the opening of the mouthpiece tube, in the inhalation phase, and another position in which the opening of the mouthpiece tube is at its maximum size, in the exhalation phase.
