Piston operating assembly for a linear compressor and method for manufacturing the same

Abstract

An integrated piston operating assembly for a linear compressor and a method for manufacturing the same are provided. The integrated piston operating assembly includes a piston coupling boss coupled to a piston, a plurality of magnets disposed in a cylindrical arrangement concentric with the piston coupling boss, and a linking member formed of a resin for connecting and thus integrating the piston coupling boss with the plurality of magnets. The magnets and piston coupling boss are secured to the linking member as the linking member is injection molded. By integrating the piston operating assembly of the linear compressor, geometric and assembling tolerances are improved, while deterioration of persistence due to processing and assembling processes is prevented.

1 - 4 . (canceled).  
     
     
         5 . A method for manufacturing a piston operating assembly for a linear compressor comprising: 
 preparing a plurality of magnets and a piston coupling boss;    assembling the plurality of magnets and the piston coupling boss in a core mold;    mounting the core mold in an injection molding machine; and    injecting a molding resin in the core mold to form an integrated piston operating assembly including the plurality of magnets and the piston coupling boss.    
     
     
         6 . The method as claimed in  claim 5 , further comprising separating the integrated piston operating assembly from the core mold.  
     
     
         7 . The method as claimed in  claim 5 , wherein each magnet has a stepped portion formed along a boundary thereof, and wherein the molding resin engages the stepped portion of the magnets to secure the magnets in the piston operating assembly.  
     
     
         8 . The method as claimed in  claim 5 , wherein the piston coupling boss is comprised of brass.  
     
     
         9 . The method as claimed in  claim 5 , wherein the piston coupling boss includes a screw portion for engaging a threaded end of a piston.
