Abstract

The present invention provides a linear compressor capable of reducing wear of a discharge valve, the linear compressor comprising: a casing provided with a discharge part; a cylinder located inside the casing to form a compression space for refrigerant; a piston configured to reciprocate axially inside the cylinder; a discharge valve disposed on one side of the cylinder to selectively discharge refrigerant compressed in the refrigerant compression space; refrigerant; a valve spring coupled with the discharge valve to provide a restoring force; and a limiter coupled with the valve spring to limit a deformation amount of the valve spring. The limiter includes a guide device, which is recessed in a direction in which the valve spring deforms, for reducing the amount of impact between the limiter and the valve spring.

Description

technical field [0001] The present invention relates to a linear compressor (Linear Compressor). 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, and is widely used in the household appliances or entire industry. [0004] If this kind of compressor is roughly classified, it can be divided into: a compression space for...
