Abstract: A linear compressor includes a shell, a discharge pipe coupled to the shell, a compressor main body located inside of the shell, a cover housing that defines a discharge space that discharges refrigerant to the discharge pipe, and a guide pipe coupled to the cover housing and configured to guide refrigerant from the discharge space to the discharge pipe. The cover housing includes a flange portion configured to couple to the compressor main body, a chamber portion that extends from the flange portion and that defines the discharge space, an accommodation groove configured to accommodate the guide pipe, and a communication groove that penetrates an inner wall of the accommodation groove and that extends to the discharge space. The guide pipe is configured to insert into the communication groove in a state in which the guide pipe is accommodated in the accommodation groove.

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.
