Description

Für.- manche Zwecken insbesondere zur Raumbelüftung in industriellen Betrieben, .werden Lüfter verwendet, deren Förderrichtung ,aus betrieblichen Gründen in einer Ebene hin und her schwenkbar ist. Man erreichte dies bisiheir.durch ein ahn Lüftermotor angebrachtes kleines Schwenkgetriebe, das aber teuer ist und unter Umständen zu Störungen An!laß geben kann..For some purposes, especially for room ventilation in industrial Operated, .fans are used, their direction of flow, for operational reasons can be pivoted back and forth in one plane. This was achieved through a bisiheir A small swivel gear attached to the fan motor, but it is expensive and under Circumstances can cause disturbances ..

Eine ',besonders, einfache und, günstige Lösunig besteht demgegenüber erfindungsgemäß diarin, daß mit dem schwenkbaren Lüfter in :dem vom Lüfter erzeugten Luftstrom eine alis Ruder wirkende Steuerplatte gelenkig verbunden. :isst, an deren Luftaustrittskan to eine zweite, kleinere Platte ebenfalls gelenskig arngebracht ist. Eine Auslenkung der zweiten, kleinerem Platte bewirkt einen entgegengesetzten Ausschlag der größeren Steuerplatte. Diadurch wird der Luftstrom aus seiner Richtung abgelenkt. Die dazu erforderliche, der Impulsänderung desLuftstromes- entsprechemdeReaktionskraft greift an der Platte an und wirkt infolge der Anlenkung der Platte am beweglichen Motor auf diesen als Moment, das zur selbsttätigen Schwenkung des Lüfters ausgenutzt wird. Um eine -oszillierende Bewegung des Lüfters zu erhalten, wird ein Iden Lüfter in der Schwenkebene beiderseitig um.fas-sen,d!er Hilfsrahmen angebracht, der auf jeder Seite einen Anschlagstift besitzt. Dieser Anschlagsti£t sorgt für die Umsteuerung der zweiten, kleineren Platte durch die Bewegung ides Lüfters selbst.In contrast, there is a 'particularly, simple and' inexpensive 'solution according to the invention diarin that with the pivotable fan in: the one generated by the fan Air flow articulated to a control plate acting as a rudder. : eats at their A second, smaller plate is also articulated with an articulated ski-mounted air outlet duct is. A deflection of the second, smaller plate causes the opposite Deflection of the larger control plate. This will make the air flow out of its direction diverted. The reaction force required for this, corresponding to the change in momentum in the air flow attacks the plate and acts as a result of the articulation of the plate on the movable one Motor on this as a moment that is used to automatically pivot the fan will. To get an oscillating movement of the fan, an Iden fan is used In the swivel plane on both sides, grasp the subframe attached to the each side has a stop pin. This stop pin takes care of the reversal the second, smaller plate by the movement of the fan itself.

Im folgenden ist die Erfindung an Hand eines in der Zeichnung ,dargestel'lten- Aus:fÜhrungsbeispiels erläutert (Rig. i und 2). z ist der um die Achse 2 schwenkbare Lwftermotor, 3 das Lüfterrad. An der mit dem Motor verbundenen. Haleerung 4 ist die Steuerplatte 5 angelenkt und an dieser wiederum d-ie zweite, kleinere Platte 6. Die Relativfhewegunigen der Platten! 5 und 6 sind durch Anschläge 7 bzw. 8 begrenzt. 9 isst ein Hilfsrahmen mit Anschlagstift io zum Umsteuern der zweiten, kleineren Platte in den Endstellungen der Schwenkung.In the following the invention is based on one in the drawing, Dargestel'lten- From: guidance example explained (Rig. I and 2). z is the pivotable about axis 2 Fan motor, 3 the fan wheel. At the one connected to the engine. Halley is 4 the control plate 5 is articulated and on this in turn the second, smaller plate 6. The relative freedom of the plates! 5 and 6 are limited by stops 7 and 8, respectively. 9 eats a subframe with stop pin io for reversing the second, smaller one Plate in the end positions of the pivoting.

Die Platten 5 und 6 werden von dem vom Lüfter erzeugten Luftstrom bestrichen. Der Ausschlag der kleineren Platte 6 in Richtung :des Pfeils i i bewirkt einen Ausschlag der Platte 5 in Richtung des Pfeils i2. Dadurch wird eine selbsttätige Schwenkung -des Lüfters um die Achse :2 in Richtung des Pfeils i3- hervorgerufen. Beim Erreichen der äußersten Schwenkstellung wird die kleinere Platte 6 durch den Stift io auf der linken Seite des Rahmens 9 umgesteuert und auf diese Weise die Schwenkung in der Gegenrichtung eingeleitet.The plates 5 and 6 are affected by the air flow generated by the fan coated. The deflection of the smaller plate 6 in the direction of the arrow i i causes a deflection of the plate 5 in the direction of arrow i2. This becomes an automatic Pivoting -of the fan about the axis: 2 in the direction of the arrow i3- caused. When reaching the extreme pivot position, the smaller plate 6 is through the Pin io on the left side of the frame 9 reversed and in this way the Pivoting initiated in the opposite direction.
