Abstract (en)
[origin: EP0615899A2] Air is inhaled from a high pressure supply via a demand valve 10, a main breathing chamber 20, and a mouthpiece 30. Exhaled air passes through chamber 20, exhaust valve 40, and a secondary chamber 50, to exit via an exhaust port 60. A buoyancy jacket can be inflated from the high pressure supply via a first button-operated valve 70 and a flexible conduit 80. The jacket can also be inflated from mouthpiece 30 by depressing a second button 90 to sealably close port 60 and open a buoyancy valve 100 between chamber 50 and conduit 80. The non-return exhaust valve 40 allows air to flow in one direction from mouthpiece to jacket but prevents reverse flow. <IMAGE>
