Abstract

A linear compressor is provided. The linear compressor may include a shell including a discharge outlet, a cylinder provided in the shell to define a compression space for a refrigerant, a frame to fix the cylinder to the shell, a piston reciprocated within the cylinder in an axial direction, a discharge valve disposed on or at one side of the cylinder to selectively discharge the refrigerant compressed in the compression space, a discharge cover coupled to the frame, the discharge cover having at least one chamber to reduce pulsation of the refrigerant discharged through the discharge valve, and a valve spring disposed on the discharge cover to provide a restoring force to the discharge valve. The discharge cover may include a cover body having a discharge hole, through which the refrigerant discharged through the discharge valve may be discharged outside of the discharge cover, and a guide passage defined in the cover body to guide at least a portion of the refrigerant discharged through the discharge valve into the at least one chamber.

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 the process of compressing, condensing, expanding, and evaporating the refrigerant is repeated. To this end, the cooling system described above includes a compressor, a condenser, an expansion device and an evaporator. Furthermore, the above-mentioned cooling system may be installed in a refrigerator or an air conditioner as a home 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 and compresses air or refrigerant or other various working gases to increase the pressure. It is widely used in the above-mentioned household appliances or the entire industry. [0004] This kind of compressor can be roughly divided into: a compression space for sucking and ...
