Beschreibung
Zusammenfassung:	The nozzle (1) has a discharge air inlet (11.1) that is arranged upstream, and an upstream channel section (11.4) with a discharge air outlet, where the section is connected upstream with the air inlet. The channel section has a diameter which has a maximum value of 1.4 millimeters. Another upstream channel section (11.2) is arranged between the inlet and the section (11.4) and has a diameter which is larger than the diameter of the section (11.4). The inlet is connected with a circular recess (11.5) on an outer side of the nozzle, where an outer contour of the nozzle tapers for the outlet. Independent claims are also included for the following: (1) a diffuser for a pneumatically operated injector for feeding coating powder (2) a pneumatically operated injector for feeding coating powder with a driving nozzle and a diffuser (3) a method for operation of an injector. Die erfindungsgemäße Treibdüse für einen pneumatisch betriebenen Injektor zum Fördern von Beschichtungspulver weist einen stromaufwärts angeordneten Förderlufteinlass (11.1) und einen damit verbundenen stromabwärtigen Kanalabschnitt (11.4) mit einem Förderluftauslass auf, wobei der Durchmesser des stromabwärtigen Kanalabschnitts (11.4) maximal 1,4 mm beträgt.
