Abstract

The invention provides a linear compressor and a refrigerator including the linear compressor. The linear compressor of the present invention includes: a housing with a suction portion; a cylinder disposed inside the housing to form a compression space for refrigerant; a piston capable of moving along the axial direction inside the cylinder. reciprocating movement; a discharge valve, located on one side of the cylinder, selectively discharges the refrigerant compressed in the refrigerant compression space; a nozzle portion, formed in the cylinder, to discharge the At least a part of the refrigerant discharged from the valve flows into the cylinder; and a filtering device is provided inside the casing. The filter device includes at least one filter member provided on a refrigerant flow path from the suction portion to the nozzle portion via the discharge valve, and the refrigerant can flow into the nozzle while passing through the at least one filter member. Impurities or oil in the refrigerant in the nozzle part are filtered.

Description

technical field [0001] The invention relates to a linear compressor and a refrigerator including the linear compressor. Background technique [0002] 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 working gases to increase the pressure. It is used in refrigerators, air conditioners, etc. Machines and other home appliances or the entire industry are widely used. [0003] Such compressors are roughly divided into: in the form of a compression space for sucking and discharging working gas between the piston (Piston) and the cylinder (Cylinder), the piston performs linear reciprocating motion inside the cylinder and compresses and refrigerates A reciprocating compressor (Reciprocating compressor) for refrigerant; a compression space for sucking and discharging working gas is formed between the eccentrically rotating roller (...
