linear compressor

Abstract

The present invention provides a linear compressor. The linear compressor according to an embodiment of the present invention includes: a cylindrical casing; a compressor body inserted into the casing; and a first casing cover coupled to the casing a rear end portion of the compressor body; a first support device coupled to the front end portion of the compressor body to support the front end portion of the compressor body; and a second support device for connecting the rear end portion of the compressor body to the The first housing cover is connected to support the rear end of the compressor body; the first support device includes: a support head, combined with the center of the front end of the compressor body; and a pair of reducing A vibration damping unit is provided, wherein both ends of the vibration damping unit are respectively connected to the support head and the inner peripheral surface of the housing.

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
