LINEAR COMPRESSOR AND METHOD OF MANUFACTURING A LINEAR COMPRESSOR

摘要

A linear compressor and a method of manufacturing a linear compressor are provided. The linear compressor may include a shell including a suction inlet, a cylinder having a compression space, in which a refrigerant suctioned in through the suction inlet may be compressed, a piston reciprocated within the cylinder, a first surface treatment disposed on an outer surface of the piston, the first surface treatment having a first hardness value, which is a measured hardness value, and a buffer disposed between the outer surface of the piston and the first surface treatment. The buffer may have a second hardness value, which is a measured hardness value. The first hardness value of the first surface treatment may be greater than the second hardness value of the buffer.

1. A linear compressor, comprising:
a shell; a cylinder having a compression space into which a refrigerant is suctioned and compressed; a piston reciprocated within the cylinder; a first surface treatment disposed on an outer circumferential surface of the piston, the first surface treatment having a first hardness value; and a buffer disposed between the outer circumferential surface of the piston and the first surface treatment, the buffer having a second hardness value, wherein the first hardness value is greater than the second hardness value.
