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.

Abstract: A linear compressor is provided that may include a cylinder which defines a compression space for a refrigerant and into which a piston that reciprocates in an axial direction may be inserted, a frame in which the cylinder may be accommodated, a discharge valve that selectively discharges the refrigerant compressed in the compression space for the refrigerant, a spring assembly coupled to the discharge valve, a discharge cover on which the spring assembly may be seated and having a discharge space through which the refrigerant discharged through the discharge valve may flow, and a first gasket seated inside of the discharge cover to support the spring assembly and attenuate vibration during an operation of the discharge valve.

Abstract: A linear compressor is provided. The linear compressor may include a shell having a cylindrical shape and a horizontal central longitudinal axis, a fixing bracket provided on an inner circumferential surface of the shell, a compressor body accommodated in the shell in a state of being spaced apart from the inner circumferential surface of the shell to compress a refrigerant, a support connected to the fixing bracket to support the compressor body, and a coupling member that connects the support to the fixing bracket. The support may include a plate spring and a buffer coupled to an edge of the plate spring. The coupling member may pass through the buffer and be coupled to the fixing bracket.
