An evaporator chamber for mixing water vapor with respiratory gas has a supply opening for the respiratory gas, an inlet opening for the water vapor and an outlet opening for the humidified respiratory gas. With the evaporator chamber, an excellent mixing is achieved with the smallest possible structural volume. The evaporator chamber is configured as a hollow body (1) having an essentially circularly-shaped inner wall surface (5). The supply opening (4) on the upper end of the hollow body (1) is arranged in a manner which conducts in the respiratory gas essentially tangentially to the inner wall surface (5). The outlet opening (6) is located at the lower end of the hollow body (1) and the inlet opening (9) lies between the supply opening (4) and the outlet opening (6).

1. An evaporator chamber for mixing water vapor with a respiratory gas, the evaporator chamber comprising: a hollow body having a wall defining an inner wall surface having an essentially cylindrical shape; said hollow body having an upper end and a lower end; said hollow body having a supply opening through which the respiratory gas is supplied essentially tangentially to said inner wall surface; said hollow body further having an inlet opening for water vapor which mixes in said hollow body with said respiratory gas to form a humidified respiratory gas; an outlet opening disposed at said lower end through which said humidified respiratory gas flows out of said hollow body; and, said supply opening being mounted at said upper end so that said outlet opening is disposed at said lower end and so that said inlet opening is arranged between said supply opening and said outlet opening. 2. The evaporator chamber of claim 1, wherein said inlet opening for said water vapor lies in the region of a center point enclosed by said cylindrically-shaped inner wall surface. 3. The evaporator chamber of claim 1, further comprising: a supply channel for conducting said respiratory gas to said supply opening; and, a first temperature sensor mounted in said supply channel upstream of said supply opening. 4. The evaporator chamber of claim 3, wherein said first temperature sensor is mounted at the same elevation as said inlet opening for said water vapor. 5. The evaporator chamber of claim 3, wherein said first temperature sensor is mounted at an elevation below said inlet opening for said water vapor. 6. The evaporator chamber of claim 3, further comprising: an outlet channel for conducting said humidified respiratory gas away from said outlet opening; a second temperature sensor mounted in said outlet channel; and, a baffle plate for shielding said second temperature sensor with respect to condensate. 7. The evaporator chamber of claim 1, further comprising a flow nozzle mounted in the region of said outlet opening.
