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.

Abstract: A linear compressor includes a shell, a frame in the shell, a cylinder defining a compression space, a piston in the cylinder, a motor assembly configured to drive the piston, a discharge cover unit defining a discharge space, a discharge valve configured to selectively open and close the compression space, and a valve spring assembly configured to provide elastic force that causes the discharge valve to contact the cylinder. The discharge cover unit includes a cover housing that defines an opening configured to communicate with the discharge space, a discharge cover that inserts into the cover housing through the opening, that contacts an inner surface of the cover housing, and that covers the opening, and a fixing ring configured to be positioned at an inner surface of the discharge cover. A thermal expansion coefficient of the fixing ring is greater than that of the discharge cover.
