Ejector Tube of an Ejector Pump

Abstract

An ejector tube ( 5 ) of an ejector pump has an inlet area ( 4 ), a mixing area ( 7 ) and an outlet end ( 8 ) via which the medium to be delivered exits the ejector tube ( 5 ). A conduit section ( 10 ) adjoins the outlet end ( 8 ), the conduit section ( 10 ) is connected to the outlet end ( 8 ) of the ejector tube ( 5 ) so as to form a single piece.

1 . An ejector tube of an ejector pump comprising an inlet area, a mixing area and an outlet end via which the medium to be delivered exits the ejector tube, and a conduit section adjoining the outlet end, wherein the conduit section is connected to the outlet end of the ejector tube so as to form a single piece. 
   
   
       2 . The ejector tube according to  claim 1 , wherein the conduit section is a corrugated tube. 
   
   
       3 . The ejector tube according to  claim 1 , wherein the conduit section is a smooth tube. 
   
   
       4 . The ejector tube according to  claim 1 , wherein the outlet end and the conduit section are made of the same material. 
   
   
       5 . The ejector tube according to  claim 1 , wherein the outlet end and the conduit section are made of different materials. 
   
   
       6 . The ejector tube according to  claim 1 , wherein the outlet end has an internal contour configured as a diffuser. 
   
   
       7 . The ejector tube according to  claim 1 , wherein the diffuser merges continuously into the internal diameter of the conduit section. 
   
   
       8 . The ejector tube according to  claim 1 , wherein the outlet end and the conduit section are made of the same material, wherein the material is polyoxymethylene (POM) or polyamide (PA). 
   
   
       9 . A method of manufacturing an ejector tube of an ejector pump comprising the steps of:
 providing an inlet area, a mixing area and an outlet end via which the medium to be delivered exits the ejector tube, and   adjoining a conduit section to the outlet end, wherein the conduit section is connected to the outlet end of the ejector tube so as to form a single piece.   
   
   
       10 . The method according to  claim 9 , wherein the conduit section is a corrugated tube. 
   
   
       11 . The method according to  claim 9 , wherein the conduit section is a smooth tube. 
   
   
       12 . The method according to  claim 9 , wherein the outlet end and the conduit section are made of the same material. 
   
   
       13 . The method according to  claim 9 , wherein the outlet end and the conduit section are made of different materials. 
   
   
       14 . The method according to  claim 9 , wherein the outlet end has an internal contour configured as a diffuser. 
   
   
       15 . The method according to  claim 9 , wherein the diffuser merges continuously into the internal diameter of the conduit section. 
   
   
       16 . The method according to  claim 9 , wherein the outlet end and the conduit section are made of the same material, wherein the material is polyoxymethylene (POM) or polyamide (PA).
