The air guidance device (6) supplies the combustion air to the oil nozzle. The device (6) is exposed to the chamber (1) in sections and the combustion air guided through the chamber (1), to allow the heat transfer from chamber (1) to the combustion air. A nozzle (7) has a narrowed cross section for flow acceleration, is connected with the chamber (1), to suck in exhaust gas (8) into the device (6). |
