Abstract

Bei einer für eine Spritzpistole bestimmten Düse mit einer einen Farbkanal (5) mit Austrittsöffnung (10) und mit einer die Austrittsöffnung (10) umgebende Ringöffnung (13) für den Austritt von Druckluft ist im Farbkanal (5) eine koaxial angeordnete Düsennadel (6) zum Öffnen und Verschließen der Austrittsöffnung (10) vorhanden. Die Düsennadel (6) ist zumindest in ihrem der Austrittsöffnung (10) benachbarten Endbereich hohl, und dieser Hohlraum (7) kann mit der Druckluftquelle verbunden werden. With a nozzle intended for a spray gun one a color channel (5) with outlet opening (10) and with an annular opening (13) surrounding the outlet opening (10) there is a coaxial in the paint channel (5) for the discharge of compressed air arranged nozzle needle (6) for opening and closing the outlet opening (10) available. The nozzle needle (6) is at least in the one adjacent to the outlet opening (10) End region hollow, and this cavity (7) can with the Compressed air source.
