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.
Claims5
A regulator for a second stage underwater breathing apparatus comprising:
- a box-like shaped regulator control chamber;
- a flexible diaphragm at one end of said chamber;
- a mouthpiece tube at another end of said chamber;
- a mouthpiece connected to said mouthpiece tube;
- an air supply connected to a side of said chamber, said air supply including an air valve, and a demand lever in said chamber connected to said valve and in engagement with said diaphragm to open and close said valve, and an adjustable air deflector hinged by one end to said chamber at a position near said air valve and extending by a free end into said mouthpiece tube, the air deflector being mounted to swing from a first position in which it partially closes the opening of said mouthpiece tube to increase cross section of the air flow passage from the air supply to the mouthpiece during the inhalation phase, and a second position in which the opening of the mouthpiece tube is at a maximum size to increase cross section of the air flow passage from the mouthpiece to a discharge valve in the exhalation phase.
