Problems solved by technology

[0023] According to such a structure, when the linear compressor is operated for a long time, the sealing member will be exposed relatively much to the gas bearing, and contraction and deformation due to heat will occur, whereby the sealing bag cannot be sealed and refrigerant leakage may occur. question
In addition, there was a problem that the sealing member loosened in the space between the cylinder and the frame

Abstract

A linear compressor comprises: a piston (130) that reciprocates in an axial direction; a cylinder (120) into which the piston (130) is inserted and which defines a compression space (P) for a refrigerant; a frame (110) coupled to an outer side of the cylinder (120); a cylinder groove (121e) defined on an outer circumferential surface of the cylinder (120); and a sealing member (129a) provided in the cylinder groove (121e), the sealing member (129a) being pressed by the frame (110); wherein a space between the outer circumferential surface of the cylinder (120) and an inner circumferential surface of the frame (110) includes: a gas pocket (110b) through which a refrigerant flows; and a sealing pocket (110c) in which the sealing member is provided.

Description

technical field [0001] The present invention relates to linear compressors. Background technique [0002] The cooling system refers to a system in which a refrigerant circulates and generates cold air, which repeatedly performs compression, condensation, expansion, and evaporation processes of the refrigerant. To this end, the cooling system includes: a compressor, a condenser, an expansion device and an evaporator. In addition, the 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 transmitted from a power generating device such as an electric motor or a turbine, and compresses air or refrigerant or other working gases to increase its pressure. Compressors are widely used in such household appliances or in the entire industrial field. [0004] Such compressors can be roughly divided into reciprocating compressors (Reciprocating compr...
