Abstract

A jet pump including a housing having a central longitudinal bore and at least one longitudinal return bore, the central bore is in fluid communication with the return bore. A nozzle is disposed in the central bore in fluid communication with a mixing section. A chamber is formed within the central bore proximate the nozzle and the mixing section. A production inlet port is formed radially through the housing between the chamber and the exterior of the housing. The top of the housing is adapted for connecting a conduit for providing the motive or power fluid to the central bore and the carried nozzle and for returning the mixed motive and production fluid from the return bore to the surface. The jet pump may further include a check valve mechanism positioned in the production inlet ports. The check valve mechanism allowing fluid flow through the port from the exterior of the housing into the central bore and substantially blocking flow through the port directed from the central bore to the exterior of the housing.

Claims

exact text as granted — not AI-modified
1 . A jet pump comprising: 
 a housing having a central longitudinal bore and at least one longitudinal return bore, the central bore in fluid communication with the return bore;    a nozzle disposed in the central bore in fluid communication with a mixing section;    a chamber formed within the central bore proximate the nozzle and the mixing section; and    a production inlet port formed radially through the housing between the chamber and the exterior of the housing.    
   
   
       2 . The jet pump of  claim 1 , wherein a bottom end of the housing is closed to fluid communication to the exterior of the housing.  
   
   
       3 . The jet pump of  claim 1 , further including: 
 a check valve mechanism disposed within the radial production inlet port; and    wherein the check valve mechanism substantially blocks fluid flow through the production inlet port from the central bore to the exterior of the housing and permits fluid flow through the production inlet port from exterior of the housing to the central bore.    
   
   
       4 . The jet pump of  claim 3 , wherein the check valve mechanism comprises a ball.  
   
   
       5 . The jet pump of  claim 3 , wherein the check valve mechanism comprises: 
 a ball movably disposed within the radial production inlet port between an interior bore end and an exterior bore end; and    a seating end connected proximate the exterior bore end having a seating surface adapted for mating with the ball.    
   
   
       6 . The jet pump of  claim 5 , further including a blocking member disposed within the radial production inlet port proximate the interior bore end adapted to prevent the ball from passing through the interior bore end.  
   
   
       7 . The jet pump of  claim 5 , wherein the seating end is removably connected proximate the exterior bore end.  
   
   
       8 . The jet pump of  claim 3 , wherein a bottom end of the housing is closed to fluid communication to the exterior of the housing.  
   
   
       9 . The jet pump of  claim 4 , wherein a bottom end of the housing is closed to fluid communication to the exterior of the housing.  
   
   
       10 . The jet pump of  claim 5 , wherein a bottom end of the housing is closed to fluid communication to the exterior of the housing.  
   
   
       11 . The jet pump of  claim 6 , wherein a bottom end of the housing is closed to fluid communication to the exterior of the housing.  
   
   
       12 . The jet pump of  claim 7 , wherein a bottom end of the housing is closed to fluid communication to the exterior of the housing.  
   
   
       13 . The jet pump of  claim 1 , wherein the housing does not comprise a standing valve.  
   
   
       14 . A jet pump comprising: 
 a housing having a central longitudinal bore and at least one longitudinal return bore, the central bore in fluid communication with the return bore;    a nozzle disposed in the central bore in fluid communication with a mixing section;    a chamber formed within the central bore proximate the nozzle and the mixing section;    a production inlet port formed radially through the housing between the chamber and the exterior of the housing; and    a check valve insert disposed within the radial production inlet port, the check valve insert comprising a ball movably disposed in a tube between a first open end and a second seating end;    wherein the check valve insert substantially blocks fluid flow through the production inlet port from the central bore to the exterior of the housing and permits fluid flow through the production inlet port from exterior of the housing to the central bore.    
   
   
       15 . The jet pump of  claim 14 , wherein a bottom end of the housing is closed to fluid communication to the exterior of the housing.  
   
   
       16 . The jet pump of  claim 14 , wherein the check valve insert is fixedly connected within the radial production inlet bore.  
   
   
       17 . The jet pump of  claim 15 , wherein the check valve insert is fixedly connected within the radial production inlet bore.  
   
   
       18 . The jet pump of  claim 14 , wherein the check valve insert is removably connected within the radial production inlet bore.  
   
   
       19 . The jet pump of  claim 15 , wherein the check valve insert is removably connected within the radial production inlet bore.  
   
   
       20 . The jet pump of  claim 14 , wherein the housing does not comprise a standing valve.
