A coating device for coating an inside of a hollow body with an atomized fluid has at least one atomizing tube enclosing an atomizing channel. A pressurized propellant gas for atomizing an unatomized fluid can be introduced into the atomizing tube. The atomizing tube has at least one outlet opening and further has at least one hollow needle having a discharge opening for the unatomized fluid. The at least one hollow needle interacts with the atomizing channel and is arranged essentially coaxially thereto. The atomizing tube and the hollow needle form a Venturi arrangement.
