ABSTRACT:
During the operation of a pressure atomization nozzle, the liquid fuel spray cone from the nozzle (4) is mixed upstream of a first orifice (3) which is placed downstream of the nozzle (4) in the outflow direction with a gaseous medium (7). In this process, the said spray cone is struck radially and/or virtually radially by the gaseous medium (7). In the process, the original spray angle from the nozzle, which is about 40.degree., is reduced to less than half. For this purpose it is sufficient if the gaseous medium (7) has a pressure of 20 mbar. The new spray angle is preserved across the first orifice (3), a second orifice (2) being provided in the outflow direction if required, the said second orifice functioning on the same principle as the first, i.e. in the case of the second orifice too, the mixture already produced is struck radially and/or virtually radially by the remaining proportion of the gaseous medium which was not used at the first orifice (3). The spray cone of the mixture is altered between a solid cone and a hollow cone by altering the spacings (D) between the nozzle (4) and the front wall of the first orifice (3) and between the rear wall of the first nozzle (3) and the front wall of the second orifice (2). In the case of two orifices (3, 2), their swallowing capacity is to be kept approximately equal.
