Linear compressor

Abstract

The present invention relates to a linear compressor. In the linear compressor, a holder 31 b is combined with a cylinder 22 in an interlocking fashion by forming a first threaded part 31 c on an inner surface of the holder 31 b , the outer side of which on an inner core 31 a is mounted, and a second threaded part 22 b on an outer surface of the cylinder 22 to correspond to the first threaded part 31 c . That is, screws are not required when the cylinder 22 and the holder 31 b are combined with each other, thus preventing the cylinder 22 from being deformed by a fastening torque of the screws.

1 . A linear compressor, comprising: 
 outer and inner stators to form a magnetic field;    a mover to move a piston while reciprocating between the outer and inner stators;    a cylinder in which a refrigerant is compressed by the moving of the piston;    a first threaded part formed on an inner surface of the inner stator; and    a second threaded part formed on an outer surface of the cylinder to engage with the first threaded part.    
   
   
       2 . The linear compressor as set forth in  claim 1 , wherein: 
 the inner stator comprises an inner core to form a magnetic flux, and a holder to fasten the inner core; and    the first threaded part is formed on an inner surface of the holder.
