Abstract

1. A hollow-cone atomizer nozzle, comprising a nozzle housing (1) in which is formed a rotationally symmetrical mixing chamber (8), a first and a second inlet bore for the liquid to be atomized and a nozzle orifice (9) at the outlet of the mixing chamber, the inlet bores being assigned valves which can be operated for the setting of the liquid part-streams, the first inlet bore (6) being arranged coaxial with the nozzle axis and the second inlet bore (3) opening eccentrically into the mixing chamber, wherein the first inlet bore opens into the mixing chamber at an angle to the nozzle axis via one or more feed bores (7).
