Abstract: A compressor and a method for assembling a compressor are provided. The compressor may include a compressor casing coupled to each of a suction inlet, into which a refrigerant may be introduced, and a discharge outlet, through which the refrigerant may be discharged, a compressor body mounted inside the compressor casing to compress the refrigerant suctioned in through the suction inlet, and then discharge the refrigerant through the discharge outlet, a noise reducing member disposed between the compressor body and the compressor casing, and at least one fixing member mounted inside the compressor casing to fix the noise reducing member to an inner wall of the compressor casing.

Abstract: A cooling system and a refrigerator including a cooling system are provided. The cooling system may include a linear compressor including a reciprocating piston and a cylinder that accommodates the piston and having an outer circumferential surface, into which a refrigerant may be introduced, a refrigerant filter device provided in the linear compressor to filter the refrigerant introduced into one or more gas inflow of the cylinder, a condenser that condenses the refrigerant compressed in the linear compressor, and a dryer that removes foreign substances or oil from the refrigerant condensed in the condenser. The dryer may include a dryer body including a refrigerant inflow, through which the refrigerant condensed in the condenser may be introduced, and a refrigerant discharge, through which the refrigerant may be discharged, and an adsorption filter accommodated in the dryer body to filter the oil in the refrigerant introduced through the refrigerant inflow.

Abstract: An linear compressor and a linear motor for a linear compressor is provided. The linear compressor may include a shell, in which a suction inlet may be provided, a cylinder disposed in the shell to define a compression space for a refrigerant, a frame coupled to an outer side of the cylinder, a piston reciprocated in an axial direction within the cylinder, a stator cover coupled to the frame, and a linear motor supported by the frame and the stator cover to provide power to the piston. The stator cover may include a body, and at least one frame coupling portion coupled to the frame. The at least one frame coupling portion may extend from the body toward the frame.
