Abstract

Begasungseinrichtung (10) zum intermittierenden Einbringen eines Gases in eine Flüssigkeit. Die Begasungseinrichtung umfasst einen rohrförmigen Einleitungskörper (12) mit einer unteren axial verlaufenden Nut (14) zur Längsverteilung des einzuleitenden Gases. Der Einleitungskörper ist von einer aus elastischem Werkstoff bestehenden Membran (16) umgeben, welche Perforationsschlitze (22) zur Einleitung des Gases in die Flüssigkeit sowie einen Bereich (24,25) umfasst, der nicht perforiert ist. Bei der Erfindung sind auf der Oberfläche des Einleitungskörpers konvexe Erhebungen (28) und konkave Übergänge (30,32) vorgesehen, durch welche der Außenumfang des Einleitungskörpers vergrößert wird und der Innenumfang der Membran-Platz zum Anlegen an den Einleitungskörper findet, ohne dass eine Faltenbildung der Membran auftritt.
