Linear compressor

Abstract

A linear compressor is provided that may include a shell having a cylindrical shape, a compressor main body inserted into the shell, a first shell cover coupled to a rear end of the shell, a first support coupled to a front end of the compressor main body that supports the front end of the compressor main body, and a second support that couples a rear end of the compressor main body to the first shell cover and supports the rear end of the compressor main body. The first support may include a support head coupled to a center of the front end of the compressor main body, and a pair of dampers having both ends respectively coupled to the support head and an inner circumferential surface of the shell.

Description

[0001] This application claims priority from Korean Patent Application No. 10-2017-0097357 filed on Jul. 31, 2017, which is hereby incorporated by reference as if fully disclosed herein. technical field [0002] The present invention relates to linear compressors. Background technique [0003] Generally speaking, a 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. It is widely used in household appliances or in the whole industrial field. [0004] Such compressors can be roughly divided into: Reciprocating compressors, which form a compression space between the piston and the cylinder to suck or discharge the working gas, so that the piston moves in a straight line inside the cylinder. While reciprocating, the refrigerant is compressed; the rotary compressor (Rotary compressor) forms a compression space for...

AI Technical Summary

Problems solved by technology

[0012] First, in order to connect the leaf spring to the compressor body and the inner peripheral surface of the casing, a large number of components including a plurality of screws are required, and the material cost is expensive

[0013] Second, due to the large number of parts, the time required for assembly work is long, and since the leaf spring and the case are connected by screws, there is a high possibility of poor screw fastening

[0014] Third, the leaf spring support structure has low noise and vibration absorption capacity compared with the coil spring support structure
