LINEAR COMPRESSOR FOR PREVENTING WEAR OF PISTON BY CROSSING COAXIALITY AND CONCENTRICITY BETWEEN MOVER AND PISTON IN OPERATION COURSE OF COMPRESSOR

摘要

PURPOSE: A linear compressor is provided to improve the production efficiency of a mover and to increase compression efficiency and reliability by keeping coaxiality and concentricity between mover and piston constant by an improved mover assembly structure. CONSTITUTION: A linear compressor is composed of an outer casing(10) for forming a compression chamber; an outer core(40) disposed in the outer casing; and a mover(20) having an inner core(24) interacting with the outer core and reciprocating in the outer core. The mover comprises a body frame(22) formed like an empty cylinder and a magnet(26) arranged along the circumferential direction of the body frame, integrally injected with the body frame, and formed with a plurality of injection material filling grooves formed on the wall surface and filled with injection materials of the body frame.
