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.
