Abstract: A linear compressor is provided. The linear compressor may include a shell including a refrigerant inlet, a cylinder provided within the shell, a piston that reciprocates within the cylinder, and a suction muffler provided movable together with the piston. The suction muffler may include a muffler main body that defines a refrigerant passage, a main body insertion portion press-fitted into the muffler main body, and a piston insertion portion press-fitted into the muffler main body to extend into the piston. The piston insertion portion may correspond to the main body insertion portion in configuration.

Abstract: A linear compressor is provided. The linear compressor may include a shell having a refrigerant inlet, a cylinder provided inside the shell, a piston that reciprocates inside the cylinder to compress a refrigerant, a motor assembly that provides a drive force to the piston, and a magnet assembly that delivers the drive force to the piston. The magnet assembly may include a magnet frame having a cylindrical shape. A permanent magnet may be installed in or on the magnet frame. A coupling plate may be coupled to a side of the magnet frame and may include a flange coupled to an end portion of the permanent magnet.

Abstract: A linear compressor is provided. The linear compressor may include a shell having a refrigerant inlet, a cylinder arranged in the shell, a piston that reciprocates in the cylinder, a motor assembly that provides a drive force to the piston and having a permanent magnet, and a frame arranged on or at a side of the motor assembly. The cylinder may include a first outer circumference with which an inner stator of the motor assembly may be combined, and a second outer circumference that extends from the first outer circumference and forcibly press-fit into the frame.
