The drawback spring (5) is provided between the insulation sleeve (4) and the insulation sleeve (8) so that during drawing of the gas nozzle back, the pressure spring is compressed so that the flow nozzle (6) draws out all combustion residuals from the gas nozzle. Cleaning of the interior of the gas nozzle (1) is comprehensive. A gas distribution ring is provided and located in the insulation sleeve (4) and takes over the valve function with a result of reduced use of combustion gas.</p> |
