Abstract (en)
[origin: EP0733352A2] The nozzle (1) has an inner space in the form of a whirl chamber (5). The whirl chamber is positioned between two opposite boundary walls (6,7) and has a spiral formed rotary boundary wall (8) rotating radially outwards. At least one first fluid supply channel (9) discharges tangentially in the whirl chamber in the area of its large radial cross-section. The lateral boundary wall (7) has a whirl chamber outlet opening (25) in its centre. A second fluid supply channel (10) is provided which extends from outwards into the whirl chamber and which discharges near the whirl chamber outlet opening via a central outlet opening (11). The area between the enclosing walls (27) of the second supply channel and within the outlet opening and the radial boundary (40) is formed as a free ring gap (12).
