摘要： A linear compressor includes a compressor body configured to compress a refrigerant. The compressor body includes a cylinder, a discharge valve, a groove, a gas hole, and a flow restrictor. The cylinder receives a piston. The discharge valve is configured to open and close one side of the cylinder and define a compression space for the refrigerant together with the piston. The groove is defined in an outer circumferential surface of the cylinder and into which at least a portion of the refrigerant discharged through the discharge valve is introduced. The gas hole is defined in the groove to pass through the cylinder. The flow restrictor includes twisting wires made of different materials and is disposed to be wound around the groove.

摘要： 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.

摘要： A linear compressor is provided that may include a shell; a compressor body accommodated in the shell to compress a refrigerant; a discharge cover assembly through which the refrigerant compressed in the compressor body may be discharged; a cover pipe that extends from the discharge cover assembly to discharge the refrigerant discharged into the discharge cover assembly to an outside of the discharge cover assembly; a discharge pipe coupled to the shell to discharge the refrigerant flowing along the cover pipe to an outside of the shell; a loop pipe having a first end connected to the cover pipe and a second end connected to the discharge pipe; and a coupling member that respectively couples both the first and second ends of the loop pipe to the cover pipe and the discharge pipe. The coupling member may include a connection member, a first portion of which is inserted into the loop pipe and a second portion of which is inserted into the discharge pipe or the cover pipe. The connection member may be formed of a steel material. At least one of the discharge pipe or the cover pipe may be formed of a steel material.
