Reciprocating electromagnetic pump

Abstract

A piston in a pump reciprocates by using forces of repulsion and attraction for an electromagnetic element toward a magnetic element. So fluid is pumped and guided with the help of several valves at different places in the pump.

1 . An electromagnetic reciprocating pump, comprising: 
 a shell, said shell comprising 
 a first room,  
 a second room,  
 a fluid entrance, and  
 a fluid exit,  
 wherein an entrance check valve is deposed at said fluid entrance and an exit check valve is deposed at said fluid exit;  
   a piston, 
 wherein said piston is deposed in said shell,  
 wherein said piston has a hollow flow path,  
 wherein a piston check valve is deposed at an end of said flow path, and  
 wherein said piston has a magnetic element; and  
   a pair of electromagnetic elements, 
 wherein said pair of electromagnetic elements is deposed on two ends of said shell respectively.  
   
   
   
       2 . The pump according to  claim 1 , 
 wherein a fluid flows to said first room from said fluid entrance through said entrance check valve; and    where in said entrance check valve prevents said fluid from returning to said fluid entrance from said first room.    
   
   
       3 . The pump according to  claim 1 , 
 wherein a fluid flows to said second room from said fluid exit through said exit check valve; and    wherein said exit check valve prevents said fluid from returning to said second room from said exit entrance.    
   
   
       4 . The pump according to  claim 1 , 
 where in a fluid flows to said second room from said first room through said piston check valve; and    wherein said exit check valve prevents said fluid from returning to said first room from said second room.    
   
   
       5 . The pump according to  claim 1 , 
 wherein said magnetic element covers on a side surface of said piston .    
   
   
       6 . The pump according to  claim 1 , 
 wherein said magnetic element is deposed on both ends of said piston.    
   
   
       7 . An electromagnetic reciprocating pump, comprising: 
 a shell, said shell having 
 a fluid entrance , and  
 a fluid exit,  
 wherein an entrance check valve is deposed at said fluid entrance and an exit check valve is deposed at said fluid exit;  
   a piston, 
 wherein said piston is deposed in said shell,  
 wherein said piston has a hollow flow path,  
 wherein a piston check valve is deposed at an end of said flow path, and  
 wherein said piston has a magnetic element; and  
   an electromagnetic elements, 
 wherein said electromagnetic element covers on a side surface of said electro-magnetic element.  
   
   
   
       8 . The pump according to  claim 7 , 
 wherein said magnetic element covers on a side surface of said piston.    
   
   
       9 . The pump according to  claim 7 , 
 where in said magnetic element is deposed on both ends of said piston.
