Abstract

A linear compressor is provided that may include a shell including a suction inlet, a cylinder provided in the shell to define a compression space for a refrigerant, a piston reciprocated in an axial direction within the cylinder, a discharge valve provided at a first side of the cylinder to selectively discharge the refrigerant compressed in the compression space, at least one nozzle, through which at least a portion of the refrigerant discharged through the discharge valve flows, the at least one nozzle being disposed in the cylinder, and at least one expansion portion that extends from the at least one nozzle to an inner circumferential surface of the cylinder, the at least one expansion portion having a flow cross-section area greater than a flow cross-section area of the at least one nozzle.

Description

technical field [0001] The present invention relates to linear compressors. Background technique [0002] The cooling system is a system that generates cool air by circulating a refrigerant, and repeats the process of compressing the refrigerant, condensing it, and evaporating the expansion agent. To this end, the cooling system described above includes a compressor, a condenser, an expansion device and an evaporator. Moreover, the above-mentioned cooling system can be installed on household appliances such as refrigerators or air conditioners. [0003] In general, a compressor (Compressor) is a mechanical device that receives power from a power generating device such as a motor or a turbine to compress air or refrigerant or other working gases and increase the pressure. It is widely used in household appliances or the entire industry. [0004] This kind of compressor can be roughly divided into: reciprocating compressor (Reciprocating compressor), which forms a compressi...
