Abstract

A linear compressor (100) comprising: a shell (101); a cylinder (120) provided in the shell (101) to define a compression space for a refrigerant; a frame (110) to fix the cylinder (120) to the shell (101); a piston (130) reciprocated within the cylinder (120) in an axial direction; a discharge valve (220) disposed at one end of the cylinder (120) to selectively discharge the refrigerant compressed in the compression space (P); a discharge cover (200) coupled to the frame (110), the discharge cover (200) having a chamber (212) to reduce pulsation of the refrigerant discharged through the discharge valve (220); a valve spring (230) installed on the discharge cover (200) to provide an elastic force to the discharge valve (220); and a stopper (240) coupled to the valve spring (230) to restrict deformation of the valve spring (230). The linear compressor further comprises: a first spacer (250) disposed between the valve spring (230) and the stopper (240) to space the valve spring (230) from the stopper (240); and a second spacer (260) installed on the cover body (200a) to support the stopper (240).

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 ...
