Abstract

A linear compressor that enables a gas bearing to easily work between a cylinder and a piston of the linear compressor. The linear compressor includes: a housing provided with a suction portion; a cylinder located inside the housing to form a compression space for refrigerant; a frame combined with the outside of the cylinder; a piston with a It can be arranged in the manner of reciprocating axially inside the cylinder; the discharge valve, which is located on one side of the cylinder, selectively discharges the refrigerant compressed in the refrigerant compression space; the flow a space portion formed between the cylinder and the frame, through which at least a part of the refrigerant discharged through the discharge valve flows; a sealing recess communicating with the flow space portion; and a sealing member for It is arranged in the sealing recess in a movable manner, and seals the space separated between the frame and the cylinder.

Description

technical field [0001] The present invention relates to linear compressors. Background technique [0002] A 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. The cooling system can be set in a refrigerator or an air conditioner as a household 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 to compress air or refrigerant or other various working gases to increase the pressure. industry. [0004] This kind of compressor can be roughly divided into: a compression space for sucking and discharging working gas is formed between the piston (Piston) and the cylinder (Cylinder), and the piston perfor...
