- The
OXY-LUNG is a chest-worn (or optional back-worn) closed-circuit
pure oxygen underwater breathing apparatus.
-
Developed for
intensive use, it has high performance, but simple design
remains. The OXY-LUNG is robust compact,
-
and it does not
require any special tools for general maintenance. It comes in
the form of a rigid unit comprising the
-
absorbent canister,
the oxygen cylinder and the breathing bag. The diver breathes
into the apparatus through a
-
mouthpiece which is
fitted with a valve and is held in the mouth by a strap and
-
connected to two
corrugated tubes which lead to the inhalation and exhalation
-
hose containing the
corresponding non-return valve. It is fitted with a pressure
-
gauge which
indicates the pressure of oxygen remaining in the cylinder. The
-
OXY-LUNG is a
self-contained demand type free diving apparatus using pure
-
oxygen in
closed-circuit. It comes standard with a cylinder contents gauge
and
-
by-pass. The
OXY-LUNG is made by Aqua-Lung in the U.S.A.
-
The oxygen consumed
is automatically replaced when, as a result of a reduction
-
in the volume of
gases in the closed-circuit, the wall of the breathing bag
-
activates the
oxygen second stage demand valve. The circulation of gases is
-
ensured by the
action of two non-return valves. The whole of the exhaled gas
-
passes directly
through the absorbent canister where the carbon dioxide is
-
100% absorbed.
-
-
BY-PASS SYSTEM
-
The OXY-LUNG is
fitted with an additional safety
-
system for the
manual supply of medium
-
pressure oxygen via
what is usually called a “bypass”.
-
This by-pass is
built into the first stage High
-
Pressure -Medium
Pressure reducing valve and
-
permits Medium
Pressure oxygen to be injected
-
directly into the
breathing bag through a pipe fitted
-
to its support
plate. The by-pass has a controlled
-
flow in order to
avoid over-rapid inflation of the
-
bag and will assure
the supply of oxygen, even
-
in the case of
failure of the second stage demand
-
valve. From a
tactical point of view, the by-pass
-
can be used jointly
with the Medium Pressure/
-
Low Pressure
handwheel to avoid the release of
-
bubbles during peek
and tactical approaches in
-
very shallow water.
