Abstract

Die Erfindung betrifft ein Saugreinigungswerkzeug für ein Saugreinigungsgerät mit einem Gehäuse (4), in dem eine Bürstenkammer (5) und eine Turbinenkammer (6) ausgebildet sind. In der Bürstenkammer (5) ist eine quer zur Arbeitsrichtung (7) des Saugreinigungswerkzeuges (1) liegende Bürstenwalze angeordnet, deren Borsten aus einem im Boden (8) der Bürstenkammer (5) ausgebildeten Saugschlitz (9) herausragen. In der Turbinenkammer (6) ist eine Luftturbine (15) zum drehenden Antrieb der Arbeitswalze (11) vorgesehen, die von einem Saugluftstrom (19) des Saugreinigungsgerätes (1) angetrieben wird. Dabei tritt der Saugluftstrom zwischen benachbarten Schaufeln (20) eines Schaufelkranzes (21) in ein schaufelfreies Zentrum (50) der Luftturbine (15) ein und durchströmt auf seinem Weg zum Abströmfenster (24) den Schaufelkranz (21) ein zweites Mal. Zur Erzielung einer hohen Leistungsausbeute bei niedrigem Geräuschniveau ist vorgesehen, den Raumquerschnitt (32) der Turbinenkammer (6) beginnend bei einem Anfangsquerschnitt (33) zu einem Endquerschnitt (30) kleiner werdend auszubilden, derart, daß sich die Turbinenkammer (6) zum Endquerschnitt (30) verjüngt.
