    Dampfstra hll uftpumpe.   



   Es   sind Dampfstrah ! pumpen bekannt,   bei denen in einer zwischen Saug- und Druckrohr befindlichen, erweiterten Kammer in bestimmter Entfernung von deren Wand Düsen angebracht sind, die mit der Kammer starr verbunden sind. 



   Diese Pumpen haben den Nachteil, dass die   Saug-bezw. Druckwirkung   nicht gleichbleibend ist, sondern mit der   Dampfspannung sich ändert.   



   Der Erfindung gemäss wird diesem Übelstande dadurch abgeholfen, dass man die Dampfdüsen verstellbar in den Boden der Kammer einsetzt, so dass man die Düsen unter verschiedenen Winkeln gegeneinander konvergieren lassen kann. Dadurch lässt sich die Vereinigung der Strahlen, je nach der Dampfspannung, immer an jener Stelle herstellen, wo die Strahlen zu expandieren beginnen und folglich das Mitreissen der Luft aufhört. 



   In der Zeichnung ist eine solche Dampfstrahlluftpumpe durch Fig. 1 im Längsschnitte und durch Fig. 2 bei abgenommenem Druckrohre in Vorderansicht dargestellt. 



   Wie ersichtlich, ist zwischen das Sangrohr a und das   Druckrohr 6   eine erweiterte Kammer c eingeschaltet, deren Boden durch die Vorderwand d der das   Saugrohrendc   umgebenden Dampfkammer f gebildet wird. In diese Vorderwand d ist eine Ringreihe von Löchern 9 gebohrt, deren jedes von einer Kugelgelenklagerschale h umgeben ist. In diese Lagerschalen passen die kugelförmigen Enden der Dampfdüsen j, die durch Überwurfmuttern k in den Lagerschalen estgehalten werden. Nach dem Lösen der Schraubenbolzen 
 EMI1.1 
 verbinden, kann man die   Muttern k lockern   und den Düsen j mit Hilfe eingesteckter Drähte die gewünschte Lage geben.

    Steam jet air pump.



   They are steam jets! pumps are known in which nozzles are attached in a located between the suction and pressure pipe, enlarged chamber at a certain distance from the wall, which are rigidly connected to the chamber.



   These pumps have the disadvantage that the suction respectively. Pressure effect is not constant, but changes with the vapor tension.



   According to the invention, this disadvantage is remedied by inserting the steam nozzles in an adjustable manner in the bottom of the chamber, so that the nozzles can be made to converge towards one another at different angles. In this way, depending on the vapor tension, the jets can always be united at the point where the jets begin to expand and consequently where the air stops being carried along.



   In the drawing, such a steam jet air pump is shown by FIG. 1 in longitudinal section and by FIG. 2 with the pressure pipes removed in a front view.



   As can be seen, an enlarged chamber c is connected between the Sangrohr a and the pressure pipe 6, the bottom of which is formed by the front wall d of the steam chamber f surrounding the Saugrohrendc. In this front wall d a ring row of holes 9 is drilled, each of which is surrounded by a ball joint bearing shell h. The spherical ends of the steam nozzles j, which are held in the bearing shells by union nuts k, fit into these bearing shells. After loosening the screw bolts
 EMI1.1
 connect, you can loosen the nuts k and give the nozzles j the desired position with the help of inserted wires.
