  • Piston operating assembly for a linear compressor and method for manufacturing the same
    Publication number: 20040223863
    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.
