Abstract

A linear compressor and a refrigerator including a linear compressor is provided. The linear compressor 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 one side of the cylinder to selectively discharge the refrigerant compressed in the compression space, at least one nozzle disposed in the cylinder to introduce at least a portion of the refrigerant discharged through the discharge valve into the cylinder, and at least one filter provided in the shell. The at least one filter may be disposed in a refrigerant passage defined from the suction inlet to the at least one nozzle via the discharge valve. Foreign substances or oil contained in the refrigerant introduced into the at least one nozzle may be filtered while passing through the at least one filter.

Description

technical field [0001] The invention relates to a linear compressor and a refrigerator including the linear compressor. Background technique [0002] 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 working gases to increase the pressure. It is used in refrigerators, air conditioners, etc. Machines and other home appliances or the entire industry are widely used. [0003] Such compressors are roughly divided into: in the form of a compression space for sucking and discharging working gas between the piston (Piston) and the cylinder (Cylinder), the piston performs linear reciprocating motion inside the cylinder and compresses and refrigerates A reciprocating compressor (Reciprocating compressor); between the eccentrically rotating roller (Roller) and the cylinder, there is a compression space for sucking and discharging the...
