ABSTRACT:
A pressure regulator for breathing apparatus which utilizes a low pressure control signal to control the inhalation of gases through the regulator. A first low pressure control valve is actuated by the diver's inhalation effort to provide a pressure signal which is used to control a main valve which supplies the breathing mixture input to the diver. Separate exhalation exhaust assist may be provided which utilizes energy from the air tank to help eject the diver's exhaust gases from the regulator.
