Problems solved by technology

[0017] (1) There is a problem that the gas refrigerant flowing to the outer peripheral surface of the piston cannot effectively support the piston
In particular, in order to effectively support the piston in the structure of the prior document 1, there is a problem that a relatively large amount of gas refrigerant needs to be supplied
[0018] (2) In addition, when a relatively large amount of gas refrigerant is supplied to the gas bearing to effectively support the piston, there is a problem that the flow rate of the refrigerant in the entire system decreases and the compression efficiency decreases
[0019] (3) In addition, there is a problem that the orifice is closed by foreign matter contained in the gas refrigerant contained in the gas inflow portion
Therefore, gas refrigerant cannot flow through the orifice, and as a result, there is a problem that a driving part such as a piston may be damaged

Abstract

The present invention relates to a linear compressor. A linear compressor according to the present invention includes: a piston reciprocating in an axial direction; a cylinder provided radially outside the piston to accommodate the piston; and a bearing inflow flow path formed through the cylinder, to supply bearing refrigerant to the piston. In addition, the bearing inflow path includes: a first bearing inflow path extending radially inward from the outer peripheral surface of the cylinder; and a second bearing inflow path extending from the first bearing inflow path to the inner peripheral surface of the cylinder. At this time, the second bearing inflow channel is formed to extend in the circumferential direction on the inner peripheral surface of the cylinder.

Description

technical field [0001] The present invention relates to a linear compressor. Background technique [0002] Generally, 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, and is widely used In the household appliances or the entire industrial field. [0003] Such compressors can be roughly classified into: reciprocating compressors, rotary compressors and scroll compressors. [0004] The reciprocating compressor forms a compression space capable of sucking or discharging working gas between a piston (Piston) and a cylinder (Cylinder), so that the piston performs linear reciprocating motion inside the cylinder and compresses the refrigerant. [0005] In addition, in the rotary compressor, a compression space for sucking or discharging working gas is formed between an eccentrically rotating rolle...
