Reconfigurable jet pump

Abstract

The present invention provides reconfigurable jet pump that is also inexpensive to fabricate. In one preferred embodiment of the present invention, a jet pump is formed as a nozzle and a diffuser attached to a standard tube or pipe T-shape fitting. Suitable T-shape fittings may have one or more joints where seals is formed by a compression/deformation of certain elements. The subject invention fulfills and important need for a jet pump that can be produced inexpensively and can be reconfigured at conform to new operating condition without the need to replace the entire unit. This feature is very important in fluid installations such as chemical plants where the physical parameters of the fluid (such as density, viscosity, bubble content, etc.) or the operating flow conditions (pressures, flow rates) are not precisely known and experimentation may be required to achieve best performance of the jet pump.

1 . A jet pump apparatus comprising:
 a) A “T”-style fluid fitting having a first in-line compression type port, a second in-line compression type port, and a side port;   b) a nozzle element installed in said first in-line compression type port; and   c) a diffuser element installed in said second in-line compression type port.   
   
   
       2 . The jet pump apparatus of  claim 1  wherein said “T”-style fluid fitting is a tube fitting. 
   
   
       3 . The jet pump apparatus of  claim 1  wherein said “T”-style fluid fitting is selected from a group consisting of a Swagelok-type fitting and an Ultra Torr-type fitting. 
   
   
       4 . The jet pump apparatus of  claim 1  wherein said nozzle element further comprises a driving nozzle. 
   
   
       5 . The jet pump apparatus of  claim 1  further comprising a suction chamber.
