Problems solved by technology

[0010] First, in order to manufacture the discharge cover, it is necessary to have multiple parts (for example: multiple cover parts, cover tubes, etc.), and it is necessary to weld the multiple parts one by one. Therefore, there is a need for skilled welders, and it is difficult to manage The problem of the size between the various parts
[0011] Second, in the process of welding the plurality of cover parts constituting the discharge cover, there is a problem that gaps may be generated due to welding, and the refrigerant leaks through the gaps.
[0012] Third, the heat generated in the process of welding the respective caps thermally deforms the caps inserted into the discharge cap assembly, whereby there is a problem that the discharge cap assembly is detached from the inside of the cap.

Embodiment Construction

[0041] Hereinafter, a linear compressor according to an embodiment of the present invention will be described in detail with reference to the drawings.

[0042] figure 1 It is a perspective view of the linear compressor of the first embodiment of the present invention.

[0043] refer to figure 1 , The linear compressor 10 of the embodiment of the present invention may include: a shell 101 forming an appearance; and a pair of shell covers coupled to both ends of the shell 101 . As an example, the housing 10 may have a cylindrical shape. The pair of case covers may include: a first case cover 102 (refer to image 3 ); and the second housing cover 103 on the refrigerant discharge side.

[0044] Specifically, a leg 50 may be combined on the lower side of the housing 101 . The feet 50 may be combined with a base of a product for setting the linear compressor 10 . As an example, the product may include a refrigerator, and the base may include a base of a machine compartment of...

Abstract

A linear compressor according to an embodiment of the present invention is characterized by comprising: a cover case forming a refrigerant discharge space; a discharge cover inserted into the cover case so as to be in contact with an inner peripheral surface of the cover case, and shielding the opened side of the cover housing; and a fixing ring provided on the inner peripheral surface of the discharge cover, the fixing ring is formed of a material with a thermal expansion coefficient greater than that of the discharge cover.

Description

technical field [0001] The present invention relates to a linear compressor. Background technique [0002] Generally, a compressor is a mechanical device that receives power from a motor or a turbine, compresses air or refrigerant or other working gases to increase the pressure, and is widely used in the household appliances or the entire industry. [0003] Such compressors can be roughly classified into reciprocating compressors, rotary compressors, and scroll compressors. [0004] Recently, among the above-mentioned reciprocating compressors, especially many developments have been made: by directly connecting the piston to the drive motor performing reciprocating linear motion, the mechanical loss caused by motion switching can be eliminated and the compression efficiency can be improved, and the compression efficiency can be improved with a simple The structure constitutes the linear compressor. [0005] Generally, a linear compressor is configured in such a way that a ...
