Nozzle Appliance for a Jet Pump and Jet Pump

Abstract

The present invention relates to a nozzle appliance for a jet pump, comprising a driving nozzle and a first suction nozzle, wherein the first suction nozzle is arranged radially outward of the driving nozzle and wherein the nozzle appliance is designed such that a fluid flow through the driving nozzle drives a fluid flow through the first suction nozzle. The invention also relates to a jet pump comprising a corresponding nozzle appliance.

1 . Nozzle appliance for a jet pump, comprising a driving nozzle and a first suction nozzle, wherein the first suction nozzle is arranged radially outward of the driving nozzle and wherein the nozzle appliance is designed such that a fluid flow through the driving nozzle drives a fluid through the first suction nozzle. 
     
     
         2 . Nozzle appliance according to  claim 1 , wherein the first suction nozzle is arranged concentrically around the driving nozzle. 
     
     
         3 . Nozzle appliance according to  claim 1 , wherein a first mixing tube is provided downstream of the driving nozzle and the first suction nozzle. 
     
     
         4 . Nozzle appliance according to  claim 3 , wherein the first mixing tube comprises a first diffusor stage at the downstream end of the first mixing tube. 
     
     
         5 . Nozzle appliance according to  claim 3 , wherein a second suction nozzle is arranged downstream of the first mixing tube, wherein the nozzle appliance is designed such that a fluid flow through the first mixing tube drives a fluid through the second suction nozzle. 
     
     
         6 . Nozzle appliance according to  claim 5 , wherein a second mixing tube is provided downstream of the first mixing tube and the second suction nozzle. 
     
     
         7 . Nozzle appliance according to  claim 6 , wherein the second mixing tube (4) comprises a second diffusor stage at the downstream end of the second mixing tube. 
     
     
         8 . Nozzle appliance according to  claim 5 , wherein a first fluid flows through the driving nozzle and a second fluid flows through the first and/or the second suction nozzle, wherein the first and second fluids are the same kinds of fluids or wherein the first and second fluids are different kinds of fluids. 
     
     
         9 . Nozzle appliance according to  claim 8 , wherein the first fluid is a gas and the second fluid is a gas and/or the second fluid is a liquid. 
     
     
         10 . Jet pump comprising at least one nozzle appliance according to  claim 1 . 
     
     
         11 . Nozzle appliance according to  claim 2 , wherein the first suction nozzle comprises an axisymmetric volume. 
     
     
         12 . Nozzle appliance according to  claim 1 , wherein the first suction nozzle comprises an axisymmetric volume. 
     
     
         13 . Nozzle appliance according to  claim 5 , wherein the second suction nozzle is arranged concentrically around the first mixing tube. 
     
     
         14 . Nozzle appliance according to  claim 5 , wherein the second suction nozzle comprises an axisymmetric volume. 
     
     
         15 . Nozzle appliance according to  claim 13 , wherein the second suction nozzle comprises an axisymmetric volume.
