Linear compressor and manufacturing method thereof

Abstract

The present invention relates to a linear compressor and a method for manufacturing the same. The linear compressor according to embodiments of the present invention comprises: a housing provided with a suction portion; a cylinder arranged inside the housing to form a compression space of refrigerant; a piston capable of performing reciprocating motion inside the cylinder in the axis direction; a discharge valve arranged to one side of the cylinder and selectively discharging the refrigerant compressed in the compression space of the refrigerant; a gas inflow portion formed on the periphery of the cylinder, at least a part of the refrigerant discharged via the discharge valve flowing into the gas inflow portion; a filter member arranged at the gas inflow portion; and a pressing member to apply pressure to the filter member.

Description

technical field [0001] The invention relates to a linear compressor and a manufacturing method thereof. Background technique [0002] The cooling system is 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 described above includes a compressor, a condenser, an expansion device and an evaporator. In addition, the above-mentioned cooling system can be installed in a refrigerator or an air conditioner as a home appliance. [0003] Generally, a compressor (Compressor) accepts power from a power generating device such as a motor or a turbine to compress air, refrigerant or other various working gases to increase the pressure. This device is used in the above-mentioned home appliances, but also in all industries middle. [0004] This kind of compressor is roughly divided into: reciprocating compressor (Reciprocating compresso...

AI Technical Summary

Problems solved by technology

[0015] However, the linear compressor disclosed in the prior art document occupies a relatively large volume, so it is not suitable for use in refrigerators that require increased internal storage space

[0016] In order to reduce the size of the above-mentioned linear compressor, it is necessary to reduce the main parts of the compressor, but at this time there is a problem that the performance of the compressor is weakened

However, the greater the operating frequency of the compressor, the greater the frictional force of the oil circulating in the interior of the compressor, resulting in a decrease in the performance of the compressor.
