Abstract
A method for preserving cavities by applying a protective layer to the interior of a hollow body. The method uses a mixing nozzle unit coupled to a rotor unit. The mixing nozzle unit is rotated about an axis of rotation and has a mixing nozzle. The mixing nozzle unit has two supply channels for the cavity preservative and for gas for atomizing the cavity preservative. The supply channels run in the direction of the axis of rotation and conduct cavity preservative and atomizing gas separately to the mixing nozzle. The mixing nozzle unit is inserted into the hollow body in the direction of the axis of rotation through an opening in the hollow body. The cavity preservative is discharged in atomized form, and the mixing nozzle unit is rotated about the axis of rotation relative to the hollow body during the discharging or between a plurality of discharging phases.
