Abstract
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.
