linear compressor

Abstract

The present invention provides a linear compressor. The linear compressor of the embodiment of the present invention includes: a compressor casing including a cylindrical casing and a pair of casing covers covering both sides of the casing; a frame , is fixed inside the housing; the cylinder is housed inside the housing to form a compression space for the refrigerant; the piston is inside the cylinder so as to be able to reciprocate linearly along the axial direction of the cylinder inserted in a moving manner to compress the refrigerant provided in the compression space; the motor assembly includes a motor that provides power for linear reciprocating motion to the piston and a motor support that supports the motor; a spring unit so that the The piston is capable of resonant motion; the rear cover supports the spring unit; and the stopper is provided on one of the pair of housing covers and vibrates along the radial direction of the cylinder when the motor assembly , the stopper is in contact with the rear cover to prevent the motor assembly from colliding with the casing.

Description

[0001] This application claims priority from Korean Patent Application No. 10-2016-0054910 filed May 3, 2016, which is hereby incorporated by reference as if fully disclosed herein. technical field [0002] The present invention relates to linear compressors. Background technique [0003] 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. [0004] 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 h...

Problems solved by technology

At this time, if the impact between the compressor body and the cover is large, it will cause a problem that the leaf spring is deformed.

[0016] The amount of impact between the compressor body and the cover increases as the axial movement (or movement distance) of the compressor body increases. The structure of the axial movement distance of the compressor body, when the compressor is transported, the possibility of deformation of the leaf spring is high
