   In   tig. t bis   3 der Zeichnung ist eine im Sinne der Neuerung konstruierte, unmittelbar vor die Saugdüse geschaltete Drosselvorrichtung in Ansicht und zwei aufeinander senkrecht 
 EMI2.1 
 werden können ; die Grenzstellungen der   beiden Klappen w,   sind in Fig. 2 in punktierter und vollgezeichneter Stellung eingezeichnet. 



   Der die federnden Klappen nt, m voneinander abdrängende Exzentet o wird in seinen verschiedenen, Stellungen dadurch festgehalten, dass der an der Aussenseite des Gehäuses a angeordnete, federnde Stellbebel h an seiner Unterseite mit einem Körnervorsprung k versehen ist, welcher in entsprechend verteilte Körnervertiefungen der   Gehäuseaussenwand   einfällt. 



   Die in Fig. 4 gezeigte   Ausführungsform   zeigt die Eigenart, dass die Schwingungsachsen der Klappen p, p in deren Längsmitte verlegt sind, wodurch die Drehmomente der auf die Flächen der Klappen wirkenden Luftdrücke sich gegenseitig aufheben und eine durch die Wirkung der   durchströmenden   Luft verursachte Vergrösserung der Spaltöffnung nicht zu befürchten ist. 



   Diese Anordnung ermöglicht   sohin,   die Federn q, welche die Klappen in der ihnen durch das Exzenter r gegebenen Lage festzuhalten haben, bedeutend schwächer zu halten, wie bei der in Fig. 1 bis 3 gezeigten Ausführungsform, wodurch der Durchgang grösserer Körper mehr wie bei letzterer begünstigt, wird. 



   PATENT-ANSPRÜCHE : 
1. Staubsaugeleitung, dadurch gekennzeichnet, dass in den an die Düse anschliessenden Leitungsteil ein einstellbares. im Sinne der Erweiterung federndes Drosselorgan eingeschaltet ist.

   In tig. t to 3 of the drawing is a throttle device constructed in the sense of the innovation and connected directly in front of the suction nozzle in view and two perpendicular to one another
 EMI2.1
 can be; the limit positions of the two flaps w are shown in Fig. 2 in dotted and fully drawn position.



   The eccentric o pushing the resilient flaps nt, m away from each other is held in its various positions in that the resilient setting lever h, which is arranged on the outside of the housing a, is provided on its underside with a center projection k which is inserted into correspondingly distributed center recesses in the housing outer wall occurs.



   The embodiment shown in Fig. 4 shows the peculiarity that the oscillation axes of the flaps p, p are moved in their longitudinal center, whereby the torques of the air pressures acting on the surfaces of the flaps cancel each other out and an increase in the air pressure caused by the effect of the air flowing through Gap opening is not to be feared.



   This arrangement thus makes it possible to keep the springs q, which have to hold the flaps in the position given them by the eccentric r, significantly weaker, as in the embodiment shown in FIGS. 1 to 3, whereby the passage of larger bodies more than in the latter is favored.



   PATENT CLAIMS:
1. vacuum line, characterized in that in the line part adjoining the nozzle, an adjustable. is switched on in the sense of the extension resilient throttle member.

 

Claims (1)

2. Ausführungsform der Einrichtung nach Anspruch 1, dadurch gekennzeichnet, dass das Drosselorgan von zwei in einem erweiterten Leitungsteile schwingbar angeordneten und durch Federn voneinander abgedrückten Klappen gebildet wird, welche durch einen, von aussen einund feststellbaren Exzenter in verschiedene Drosselstellungen gebracht werden können. 2. Embodiment of the device according to claim 1, characterized in that the throttle member is formed by two flaps which are swingably arranged in an enlarged line part and pressed from one another by springs and which can be brought into different throttle positions by an eccentric which can be locked in and out from outside. 3. Ausführungsform der Einrichtung nach Anspruch 1 und 2, dadurch gekennzeichnet. EMI2.2 3. embodiment of the device according to claim 1 and 2, characterized. EMI2.2
