Abstract: A linear compressor includes a piston that reciprocates on a spring central axis extending in an axial direction and a spring that axially elastically supports the piston. The spring includes a plurality of spring strands. The spring strands each include a spring body spirally extending along a spring central axis C, a front spring link forming an end of the spring body by extending from a side of the spring body, and a rear spring link forming the other end of the spring body by extending from the other side of the spring body. Of the spring strands, the front spring links are disposed axially in the same plane P1 and the rear spring links are disposed axially in the same plane P2.

Abstract: A compressor is provided that may include a cylinder comprising at least one gas inlet formed on an outer circumferential surface, the cylinder being formed in a cylindrical shape; a piston disposed inside of the cylinder and configured to reciprocate axially; a spring supporter disposed outside of the cylinder and coupled to a rear of the piston; a resonant spring coupled to the spring supporter; a magnet frame coupled to a front of the spring supporter; and a mover disposed on the magnet frame. The at least one gas inlet may include a first gas inlet, and a second gas inlet disposed at a rear of the first gas inlet. A straight line extending radially from a center of mass of the piston, the spring supporter, the magnet frame, and the mover may be disposed between the first gas inlet and the second gas inlet.
