ABSTRACT:
The atomizer nozzle exhibits an internal chamber (1) and an external chamber (2) which surrounds the latter in the form of a jacket, which chambers are provided with several outlet openings (9, 10 and 11, 12) which are in alignment in each case. A proportion of the atomizer air supplied via an air duct (5) flows into the internal chamber (1) and is essentially used there for uniformly distributing a liquid fuel, which is also flowing into the internal chamber (1) from a fuel duct (3), to its outlet openings (9, 10). The remaining greater proportion of the atomizer air flows around the internal chamber (1) through the external chamber (2) and is concentrically mixed in with the coarsely atomized fuel emerging from the outlet openings (9, 10) of the internal chamber (1). This prevents liquid fuel fragments from coming into contact with the walls of the outlet openings (11, 12) of the external chamber (2), and a high atomization quality is achieved.
