    Abstract: A linear compressor is provided that may include a shell including a refrigerant inlet, a cylinder provided within the shell, a piston reciprocated within the cylinder, the piston having a flow space in which a refrigerant may flow, a motor assembly that provides a drive force, the motor assembly including a permanent magnet, a flange that extends from an end of the piston in a radial direction, the flange having an opening that communicates with the flow space of the piston and a coupling hole defined outside of the opening, a support coupled to the coupling surface of the flange to support a plurality of springs, and at least one reinforcing rib that protrudes from the coupling surface to guide deformation of the flange while the flange and the support are coupled to each other.

    Abstract: 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.

    Abstract: A linear compressor and a linear motor are provided. The linear motor may include a first stator, a second stator spaced apart from the first stator, and a permanent magnet disposed to be movable in a first direction between the first and second stators. The first stator may include a bobbin with a coil wound thereon, and a stator core that surrounds the bobbin. The stator core may be located between the second stator and the coil and may include first and second magnetic poles spaced apart from each other. One portion or entire portions of each of the first and second magnetic poles may have a constant magnetic path width within a range of a movement trajectory of the permanent magnet.

    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.
