Abstract

The invention provides a linear compressor. The linear compressor can enable a gas bearing to easily work between a cylinder and a piston of the linear compressor. The linear compressor comprises a housing, a cylinder, a framework, a piston, an exhaust valve, a flow space part, a sealing recess and a sealing part, wherein the housing is provided with a suction part; the cylinder is arranged in the housing and form the compression space for a refrigerating fluid; the framework is combined with the outside of the cylinder; the piston can perform reciprocating motion in the axial direction in the cylinder; the exhaust valve is arranged at one side of the cylinder, and selectively exhausts the refrigerating fluid compressed in the compression space; the flow space part is formed between the cylinder and the framework, and enables at least part of the exhausted refrigerating fluid to flow; the sealing recess communicates with the flow space part; and the sealing part is arranged in the sealing recess movably, and can seal the separated space between the framework 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...
