Abstract

Die Erfindung betrifft eine Flachstrahldüse mit einem Mundstück, das eine Austrittsöffnung und eine Austrittskammer mit einem sich zur Austrittsöffnung verjüngenden Querschnitt aufweist, und mit einem Strahlrichter, der erfindungsgemäß als Scheibe ausgebildet ist, die eine zentrale Öffnung sowie sich in sternförmiger rotationssymmetrischer Anordnung um die zentrale Öffnung erstreckende weitere Öffnungen besitzt, deren Querschnitt sich von außen nach innen verkleinert.

Figure imgaf001
The invention relates to a flat jet nozzle with a mouthpiece which has an outlet opening and an outlet chamber with a tapering to the outlet opening cross-section, and with a jet straightener, which is formed according to the invention as a disc having a central opening and in a star-shaped rotationally symmetrical arrangement around the central opening has extending further openings whose cross-section decreases from outside to inside.
