11.1 Operating Principle
The following image illustrates the operating principle of the vaporizer.
Control dial position above 0--Vaporizer switched on:
Fresh gas
Fresh gas mixed with anesthetic gas
The fresh gas is routed through valves J and K, which are linked to the control dial A, and through the
vaporizing chamber G.
Fresh gas enters by the inlet D. Some of the fresh gas is routed through the vaporizing chamber G, and
charged with anesthetic agent in soaked wick F. The rest of the fresh gas is routed past the airway I and
through the temperature compensator E.
