 <Desc/Clms Page number 2> 

 Anwendung der erfindungsgemässen Lösung bei der Hälfte des Strahlmitteldurchsatzes erreicht. Die Gasförderleistung der Strahlpumpe konnte gegenüber einer Strahlpumpe mit herkömmlichen Düsen bei gleichem Strahlmitteldurchsatz um zirka 50%   erhöht   werden. 



   In den Zeichnungen ist der Gegenstand der Erfindung an einem Ausführungsbeispiel näher schematisch veranschaulicht. Fig. l ist ein Schnitt durch eine   Strahl-und Diffusordüse   und Fig. 2 ein Schnitt nach der Linie A-A in Fig. 1. 



   In die Strahldüse --1-- ist der Kern --2-- eingesetzt, der ein Dreikantprofil mit abgeflachten Ecken besitzt. Im oberen Teil tragen die abgeflachten Ecken ein Feingewinde, mit dessen Hilfe der 
 EMI2.1 
 technischen Forderungen angepasst.

  Device for improving and adjusting the performance of jet pumps
 EMI1.1
 

 <Desc / Clms Page number 2>

 Use of the solution according to the invention achieved at half the blasting medium throughput. The gas delivery rate of the jet pump could be increased by around 50% compared to a jet pump with conventional nozzles with the same blasting agent throughput.



   In the drawings, the subject matter of the invention is illustrated in more detail using an exemplary embodiment. FIG. 1 is a section through a jet and diffuser nozzle and FIG. 2 is a section along the line A-A in FIG.



   The core --2--, which has a triangular profile with flattened corners, is inserted into the jet nozzle --1--. In the upper part, the flattened corners have a fine thread, with the help of which the
 EMI2.1
 adapted to technical requirements.
