摘要： A linear compressor includes a cylinder that defines a compression space for a refrigerant, a frame that fixes the cylinder to a shell, a piston that axially reciprocates in an interior of the cylinder, a discharge valve that is provided in front of the cylinder to selectively discharge the refrigerator compressed in the compression space for the refrigerant, a discharge cover that is coupled to the frame and has a discharge space for the refrigerant discharged through the discharge valve, a valve spring that provides an axial resilient force to the discharge valve while supporting the discharge valve, and a valve support device that is coupled to the valve spring and supported by the frame to deliver vibration generated by the discharge valve to the frame.

摘要： 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.
