Abstract

A linear compressor is provided that may include a shell in which a discharge port is provided, a cylinder disposed in the shell to define a compression space for a refrigerant, a piston disposed to be reciprocated in an axial direction within the cylinder, a discharge valve disposed on or at one side of the cylinder to selectively discharge the refrigerant compressed in the compression space, the discharge valve including an insertion protrusion, and a valve spring coupled to the discharge valve to provide a restoring force to the discharge valve. The valve spring may include a spring body having a central portion defined at a portion corresponding to a center of the cylinder, and an insertion hole defined in the spring body. The insertion hole may be coupled to the insertion protrusion of the discharge valve. The central portion of the spring body may be spaced apart from a central portion of the insertion hole.

Description

technical field [0001] The present invention relates to linear compressors. Background technique [0002] The so-called cooling system refers to a system that circulates a refrigerant to generate cold air, and repeatedly performs the compression, condensation, expansion, and evaporation processes of the refrigerant. To this end, the cooling system comprises a compressor, a condenser, an expansion device and an evaporator. Moreover, the cooling system may be installed in a refrigerator or an air conditioner as a home appliance. [0003] Generally speaking, a compressor (Compressor) is a mechanical device that receives power from a power generating device such as an electric motor or a turbine and compresses air or refrigerant or other various working gases to increase the pressure. industry. [0004] If this kind of compressor is roughly classified, it can be divided into: a compression space for sucking and discharging working gas is formed between the piston (Piston) and...
