Abstract
Es sind schon Saugstrahlpumpen bekannt, mit einer Düsenöffnung, die in einen Mischkanal mündet, und mit einer in den Mischkanal mündenden Ansaugöffnung, wobei die Düsenöffnung eine Düsenachse, der Mischkanal eine Mischkanalachse und die Ansaugöffnung eine Ansaugöffnungsachse aufweist. Die Düsenöffnung ist derart angeordnet, dass die Düsenachse zur Mischkanalachse fluchtet. Dadurch sind die Düsenöffnung und der Mischkanal koaxial zueinander angeordnet. Bei der erfindungsgemäßen Saugstrahlpumpe wird die Förderleistung erhöht. Erfindungsgemäß ist vorgesehen, dass die Düsenachse (2.1) der Düsenöffnung (2) bezüglich der Mischkanalachse (3) in Richtung der Ansaugöffnung (4) versetzt ist.There are already known suction jet pumps, with a nozzle opening, which opens into a mixing channel, and with an opening into the mixing channel suction, wherein the nozzle opening has a nozzle axis, the mixing channel a mixing channel axis and the suction opening a Ansaugöffnungsachse. The nozzle opening is arranged such that the nozzle axis is aligned with the mixing channel axis. As a result, the nozzle opening and the mixing channel are arranged coaxially with each other. In the suction jet pump according to the invention, the delivery rate is increased. According to the invention, it is provided that the nozzle axis (2.1) of the nozzle opening (2) is offset with respect to the mixing channel axis (3) in the direction of the suction opening (4).
Description
Stand der Technik State of the art
Die Erfindung geht aus von einer Saugstrahlpumpe nach der Gattung des Hauptanspruchs. Es ist schon eine Saugstrahlpumpe aus der
Vorteile der Erfindung Advantages of the invention
Die erfindungsgemäße Saugstrahlpumpe mit den kennzeichnenden Merkmalen des Hauptanspruchs hat demgegenüber den Vorteil, dass die Förderleistung der Saugstrahlpumpe erhöht wird, indem die Düsenachse der Düsenöffnung bezüglich der Mischkanalachse in Richtung der Ansaugöffnung versetzt angeordnet ist. Mit anderen Worten ausgedrückt führt die Düsenachse der Düsenöffnung außermittig in den Mischkanal, wobei der Versatz der Düsenachse in Bezug zur Mischkanalachse in Richtung der Ansaugöffnung vorgesehen ist. The suction jet pump according to the invention with the characterizing features of the main claim has the advantage that the delivery rate of the suction jet pump is increased by the nozzle axis of the nozzle opening is offset with respect to the mixing channel axis in the direction of the suction. In other words, the nozzle axis of the nozzle opening leads off-center into the mixing channel, wherein the offset of the nozzle axis is provided in relation to the mixing channel axis in the direction of the suction opening.
Durch die in den Unteransprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen der im Hauptanspruch angegebenen Saugstrahlpumpe möglich. The measures listed in the dependent claims advantageous refinements and improvements of the main claim suction jet pump are possible.
Vorteilhaft ist, wenn die Düsenachse nach einem ersten Ausführungsbeispiel zur Mischkanalachse parallel angeordnet ist, da der parallele Versatz der Achsen leichter herstellbar ist. It is advantageous if the nozzle axis according to a first embodiment is arranged parallel to the mixing channel axis, since the parallel offset of the axes is easier to produce.
Weiterhin vorteilhaft ist, wenn die Düsenachse nach einem zweiten Ausführungsbeispiel bezüglich der Mischkanalachse schräg angeordnet ist, wobei zwischen der der Düsenachse und der Mischkanalachse ein spitzer Winkel α vorgesehen ist, insbesondere ein Winkel α zwischen 0,1 und 15 Grad, insbesondere zwischen 0,1 und 10 Grad. Auf diese Weise wird ein schräger Versatz der Achsen erreicht, der eine höhere Förderleistung ermöglicht als bei einem parallelen Versatz der Achsen. It is also advantageous if the nozzle axis is arranged obliquely with respect to the mixing channel axis according to a second embodiment, wherein between the nozzle axis and the mixing channel axis an acute angle α is provided, in particular an angle α between 0.1 and 15 degrees, in particular between 0.1 and 10 degrees. In this way, an oblique offset of the axes is achieved, which allows a higher capacity than a parallel offset of the axes.
Außerdem vorteilhaft ist, wenn die Düsenöffnung einstückig am Gehäuse der Saugstrahlpumpe ausgebildet ist, da sich die Saugstrahlpumpe auf diese Weise sehr kostengünstig herstellen lässt. It is also advantageous if the nozzle opening is formed integrally on the housing of the suction jet pump, since the suction jet pump can be produced very inexpensively in this way.
