Abstract: A linear compressor is provided that may include a compressor casing including a cylindrical shell and a pair of shell that covers both ends of the shell; a frame fixed to an inside of the shell; a cylinder accommodated in the shell and defining a compression space for a refrigerant; a piston inserted into the cylinder to linearly reciprocate in an axial direction of the cylinder and compress the refrigerant provided to the compression space; a motor assembly including a motor that provides power for a linear reciprocating motion to the piston, and a motor support that supports the motor; a spring that allows a resonant motion of the piston; a back cover that supports the spring; and a stopper provided in one of the pair of shell covers and contacting the back cover when the motor assembly vibrates in a radial direction of the cylinder, thereby preventing the motor assembly from colliding with the shell.

Abstract: Provided is a linear compressor. Provided is a linear compressor. The linear compressor includes a shell defining an internal space, a compressor body disposed in the internal space, and a passage guide disposed between the shell and the compressor body. The passage guide may include a first guide part extending along an inner surface of the shell in an axial direction and a second guide part extending from the first guide part to the compressor body in a radial direction.

Abstract: A linear compressor is provided. The linear compressor may include a shell having a cylindrical shape, a shell cover that covers both open ends of the shell, a cylinder accommodated into the shell and defining a compression space for a refrigerant, a piston that reciprocates within the cylinder in an axial direction to compress the refrigerant within the compression space, a motor assembly including a motor that provides power to the piston and a stator cover that supports the motor, and resonant springs seated on the stator cover that support the piston to allow the piston to perform a resonant motion. The resonant springs may be circularly arranged at three points having a same interval around a center in an axial direction.
